@@autodiagyt As an apprentice 30 years ago I was low key mocked by the qualified tradesmen for wanting to learn to understand even the basics like the ignition waveform on the tunescope. I even took the manual home at night to read and learn.
Oh I’ve seen a lot of strange causes in almost 50 yrs. (I’m not Scotty K). I’ve climbed in trunks when younger, seen all manner of owner induced problems but these seem related to poorly made electronics a lot of times. I agree with comment above. Create one such as trunk light and go through motions of tracking it down. Very few are cut and dried. Good luck.

Great comment, Del. Technology advances so fast, that even the specialists have a hard time keeping up at times! On the other hand there are no boring moments in this field. You are right that if you don't practice hands-on every day, then it's even harder to keep up!
I’m a retired 76 year old master tech with an AA in electronics, HVAC Universal license and 1st Class FCC license. Watching this guy makes me feel dumb .
For cases like this it would be really interesting to use pico serial decoding to get the CAN ID of that first message that appears on wakeup. Once you have the message ID, you could find out which module that belongs to by just monitoring the network in a normal ignition on state, and pulling fuses for each module on the network until the ID of interest disappears. For this to work you would need to sample the network at a high enough rate to be able to decode it, and also use the very first message only, as once one module has started transmitting it may wake other modules as well.
I was just coming to write your comment as I downloaded the pico data and see that the sample rate isn't enough to do serial decode. A parallel suggestion would be that there are purpose-built CAN decoders/encoders that could be connected to the network to do this capture a little more simply if you want the serial and not needing the waveform. There's some information over on redit's CarHacking subredit in a pinned post and sidebar.
Customer complaint proved! Now the challenge is finding which module or modules awaken and hopefully the cause. It is a bummer when the only thing you find is the module that awakens and not what actually awakens the module. I appreciate the module could be faulty, however identifying the module is only one part of the diagnosis. the other is determining if it is a faulty module or if it is an external issue that is buried in the depths of the vehicle or wiring loom somewhere, either OEM or worse still, aftermarket. Either way, confirming the root cause before calling the module could be an expensive bugger. I am looking forward to part 2.
i used to have a lot of parasitic draws was always able to figure it out checking fuses with meter finally got a scope and haven't had one yet hope i don't forget how when it happens. beauty of UA-cam is i can pull up so many of your videos to get me started
Wow, Ivan that was really cool diagnosis of the parasitic draw!! Glad you had the experience to find out right down to brass tacks!!! Nice job Ivan. Let's see what happens in part 2.. i bet it is the cluster or the radio problem, as i remember your past videos!
Thank you Ivan for showing how valuable a scope can be in helping track down misbehaving modules like this. Knowing the info you just gathered from the scope will seriously cut down the list of suspects in this case study. Your right though. Without the help of the scope, a problem like this could take days, or even weeks to hopefully discover the problem. And would most likely allude someone like me from ever finding it. I can't wait to see what you find in part 2.
Ivan, you tend to focus on the fact that Ford vehicles take extended time to go to sleep. I bought my Mercury when it had 92 miles on it and was being used as a demonstrator. I got the car home and was admiring my new car (I have grown up since then!) and suddenly the air compressor started (it is equipped with rear-air-suspension.) I talked to a technician at the dealership and he told me that air compressor can run up to 29 minutes after the ignition has been cycled. That car is 27 years old. So, I can conclude that has been going on for many years. Great video!
Some cars will run the HVAC blower roughly 10 minutes after the vehicle is shut off (with the AC on) to dry the evaporator. I know Saturn used to do it, I haven't noticed in in a while though, but I don't doubt many euro cars do it today.
Just thought I would let you know my favorite tool to find parasitic draws in general is a thermal camera. Found a P.A.T.S. module awake in a Lincoln Navigator last time I used it and it was behind the dash. Found in about 20 seconds.
Simply amazing! And there's no way any dealer can do what you are doing, they would not have the patience, and I would guess that their techs would not have the training. Can't wait for the mystery to be solved.
Not all dealer techs are what you think they are. Quite a good bit of them are top notch. It's the industry, flat rate, managers, advisers and customers that expect Techs to have 1 hour or less crystal ball diagnostic abilities. For those that are able to tackle in depth diagnostics, they also have to balance other jobs to maintain a paycheck. That in itself pulls their focus away from such in depth jobs.
I was a Ford tech for 17 years in Canada. My shop was hourly not flat rate, so jobs like these paid the same as any gravy job so they got the attention they needed. I did lots of diag on parasitic draws, only wish that I had learned to use a scope sooner! Just love seeing scopes put to use like this
its not that they are trained, its that dealerships are driven by work completed per hour. diagnosing a car for more than an hour places that worker in a bad spot as they have now gone more than 2 hours without completing a car. diagnosing cars doesnt pay the rent. firing the parts cannon does. they will 100% replace your whole engine then realize the real issue was just a $10 part without telling you. 100% of the time.
Very interesting case, if not annoying for being intermittent! Thought process of a real Sherlock Holmes, Ivan 🙂Like most network problems, impossible to have a clue without a scope. I find it maybe telling, that there is only a slight increase in current, before it triggers an event that wakes the network. If it weren't regular like a clock, I would say a parasitic current somewhere (green crusties or water intrusion), but being so regular, it must be a module on its own. Curious to see which one is the culprit - let Part 2 begin soon 🙂
Hopefully the wiring diagram will be helpful in locating the problem module. Taking the problem CAN network out from the gateway loop or taking it apart also called isolation is the best way to find the problem, IF you can do that. THIS problem should be "Very Interesting!" Very much looking forward to part 2 ! !
Fordtechmakuloco has a parasitic draw video from a year ago or so. On a Ford escape. Rear wiper motor was seized but module was attempting to PARK the arm. Pulled upto 4amps for 10secs. Killing battery over night.
Oscilloscopes are awesome tools. I was a computer software engineer (retiired now), and for much of my career, I kept an actual old fashion analog oscilloscope on the workbench next to my desk along with a variable power supply, a digital multimeter, and a signal generator. Those were the basic tools of an electronics bench technician in the 1970s-90s, but I found that o-scope useful for all sorts of realtime computer software debugging, as I was working on IO device drivers much of my career.
3 amps for 10 seconds every 100 seconds is only 0.3 amps average. Your typical car battery is at least 50 amp-hours so it should hold out for at least 100 hours. So it should not be dying overnight, more like after 4 days or so. Or maybe the stress of losing 1/4 of the charge and recharging that much the next day, maybe that wore out or dried up the battery. Waiting for part 2!!
@@dizzy2020 I understand that one can't describe a battery with just one number, the power curve is going to be a bit .... curved. But not to the extent that a 300 milliamp load will discharge a battery "overnight"! That's over ten times the expected discharge rate. But then on the other hand, if the battery has been repeatedly discharged to zero many times, it's amp-hour capacity can be greatly diminished, even if it's relatively new. Long ago my father had a mercury with a tit-switch controlling the trunk light. If you parked the car on a hill, facing down, the trunk light would go on and discharge the battery quite a bit overnight, leading to eventual battery failure.
Thank you for your time and video of this issue! I was having the same problem and after a quick youtube search found your video. After watching i started taking off the side panel trim and unplugged as you stated. Wahla! It worked. Been a couple weeks and hasn't drain the battery since. Save me hundreds of dollars if not more. No way a dealership wouldve done this.
Ran across your video - Well done - I have 2016 MKX that is experience a parasitic draw as well - Thinking it is having the same issue - Telematic Control Module - I believe that module is 3G based and with the U.S. shutting down the 3G network in 2021 I am thinking that module is continually trying to connect to the network and never shutting down which would cause the drain - I know Lincoln offers a upgrade to the 4G work but is outrageously priced. Let me know thought if you think that could be it
You are a genius to diagnose this parasitic draw. Similar to looking for the proverbial needle in a haystack. You should take bets on which module(s) are the culprit.
With these PITA wakeups I wonder if it would be beneficial to have something listening to the CANBUS(es) and logging the addresses of the transmitters to track down which module is behind the problem more easily.
Oh boy, this one is gonna be fun. Can’t wait for the solution. I too have a “parasitic draw” Ivan….known as a wife and kids in college…😂😂 Not as easy to replace those modules, need a NPR repair. Always a great ride my man.
IVAN, AWESOME thought process and approach brother you right on modern cars to diagnose electrical problem a SCOPE is must with out it you go no where to find the problem thanks for sharing and as always learning form the best. cheeeeeeers
Hey Ivan! Long time, no see! (MY fault). Man, that thing is CRAZY complicated. THIRTY modules!! Insanity! Imagine one of these in a flood - you'd end up burning it trying to diagnose it, LOL! 🤣Can't wait to see the cause of this one. 👍😎👍
I wonder if it is possible to read that data that is being transferred. If so, maybe the modules ID themselves when the talk to each other. You have great troubleshooting skills, Ivan!
Have to love all these vehicles that have loaded up to the gills options. Really just more chances and opportunities for things to go haywire. I wonder what else is in the high speed three can? Maybe it's that module under the headliner again?
What is concerning me more than anything is the fact that these cars are taking multiple hours/days to diagnose. I just don't see this fitting in with the dealership business model. It isn't likely a service writer/dealership is going to commit the time, training, equipment and expertise to properly diagnose these issues. The best part, these are NEW cars. What will they be like in the future? Great vodep!
Can you imagine what will happen by the time they are on third owner? Talking about bypassing circuits , taped up twisted wires and unmarked toggle switches everywhere 🤔
Is it possible to have a modern US domestic vehicle with less than 30 modules? 😂 I think we surpassed the reliability limit a long time ago… Very interesting case study, Ivan 👍
@@user-fn6pq9tp2g the R&D budget on aircraft is much higher, things are only fitted for a practical purpose - and they're still allowed to use "proper" solder with lead in it. Lead free solder is one of the main causes of failure, whether it's tin whiskers or cracked joints on connectors or anything with significant thermal cycling. The ones I see the most are Ford Focus clusters for crank no start and Fiat "Blue&Me" modules for flashing mileage and parasitic drain.
Someone mentioned in a comment how locking your vehicle can prevent some electrical draws, not sure if this is true. I think the commenter was talking specifically about Subaru's.
Looking over your shoulder, I see the XL-7, the Mystique, and the MPV. It sure does look like that Probe you featured for the Halloween Special is parked up there as well. Are you going to be doing work on it in the future? Would be interesting!
I thought Ivan was becoming a Probe Specialist. Actually that sounds kind of weird. That could easily be misinterpreted. Though, those customers could be very interesting. And the case studies would be really interesting. Part 1 - Look what I found. Part 2 - How did that get in there. Ford Probe jokes. Glad I could use them again. I thought they were gone forever.
Is it possible to narrow down the cause quicker by looking at the fuse boxes through an infrared camera? Surely the circuits that are drawing a lot of current will be obvious when contrasted with the sleeping circuits?
Ivan... U have forgotten what you have taught us!!! 3amp draw for 10seconds. I just timed myself!! I can test 7 fuses for a voltage in 10s!!! every 1m 47s I can test 7 more fuses!!! I would have tested all the fuses in the car before you finished reading the circuit diagram, installed pinch clips and setup the scope!!! This is what you taught us! :) LOL...
@@PineHollowAutoDiagnostics lol. in a year u will be showing the actual data being sent on the line. I would assume that data actually says "im module xyz whats up yall?" I assume the voltage drop method would be helpful here though
In this scenario, would it have been more useful to hook up a graphic DMM or something like a 1 channel scope in series with the battery to catch that 3A spike event rather than a regular DMM? It seemed like luck that Ivan was able to catch the event as it happened on the DMM. With something graphing, even if you missed it you could look back in history and see the spike. In this case it seemed important to catch the 3A event since it gave a clue that a module was waking up and then going back to sleep. Otherwise you would only be chasing that constant 65mA draw. I'm looking forward to part 2 since it seems like there may be 2 separate issues. What is causing the 3A spike and then the "resting" 65mA draw.
@@PineHollowAutoDiagnostics I think I've seen in previous videos of yours the Snap On Vantage can graph Amperage. Or could you use an amp clamp around the negative cable and graph that way? Maybe I'm dreaming of a magical tool that doesn't exist 😆. Forgive me. I'm not a tech. I'm an accountant who is really into cars and enjoys learning new things.
@@kv2280 yes actually the old Vantage could graph current! Wish the Pico could too. Current clamps have too much drift over time, especially at the milliamps scale. Accounting and diagnostics have some key things in common like being precise with numbers and keeping careful notes 😁👍
and the vantage pro does internal amps. the last great scope meter snap on made. does things newer versions can’t, and has a long long data memory, so perfect for a job like battery draw. wish somebody still made a tool like the original vantage or the vantage pro. a real time graphing multimeter is a very handy thing. i love the vantage pro so much that i finally found two of them.
Just acquired grandfather’s 2016 3.7L MKX, has only 12,000 miles. Put new battery, air filters etc, drove home 750 miles. Week later battery draining parked overnight. Unplugged a AAA device from port under steering column thinking that maybe cause. Now battery holding for days but on last road-trip and since last jumpstart the Nav and infotainment have gone black? Car driving fine just missing all the tech
I'm about 9 mins in and wondering, if ambient temp was cold enough, one couldn't watch the fuse box with an IR camera when the amps spiked up and get an idea which fuse was heating up then see which modules were powered on that fuse. Together with your scoping the different networks might narrow it down to a single, or very few, modules really quickly
I think my 2017 lincoln mkx is having same issue.. replaced battery, battery has been checked, there seems to be a draw someplace.. I've noticed when I turn it off and walk away, internal lights dim and go out, but my radio knob back lights stay on.. with key fob in house.. however, when I lock the car, the backlights turn off. I'm thinking this may be the draw and may be draining the battery. my dealer charges 200 per hour so not sure if I want to take it there of if they can even fix it. in meantime I bought a NOCO Boost Plus and will keep it with the car in case it won't start.. and will try locking the car each night to see if that fixes the issue.
I recently bought a scope for can wiring diagnosis I just wonder where do you hook up your leads to? Most can networks have + and -, does it matter which one you hook up to?
Looks a new model to be giving trouble. Isolating the networks has done the business. Very time consuming exercise but seems to be showing results. 3 amps is a bit over the top. Too troublesome for a dealer, especially with the extended timeframe involved. You'll soon be crowned 👑 of the parasitic draw division.
Oh no, I hope that isn't the same Probe from Halloween I see in the background. Though, what are the chances it's a different one. If it is a different one, Ivan must have seen a business opportunity specializing in 25 year old Ford Probes that surprisingly no one else saw.
HS3 has mostly audio and user interface devices, including instrument cluster and telemetrics. I'm gonna throw a wild guess at either the cd player or FDIM. lol
The cause of this is the "welcome" feature on your Lincoln (when your car seems to wake up once you get close enough to it with your key fob). If your Lincoln is dying overnight it's because you're parking your car close to the house or in the garage, and keeping your keys in a spot close enough to initiate the "welcome" feature, door never opens, allowing it to fade out, and then once off it re initiates the same feature and same cycle over and over until your battery completely dies....you're welcome. And if you actually watched this whole video ... 🤦 You'll never get that time back
I have a 2009 mks when the temperature outside raises or my defrost is on my electrical components such as my radio/navigation and climate controls go out. it also tells me that all of my doors are open. I’ve checked battery fuses altanater im lost as to what i need to check next
@@PineHollowAutoDiagnostics I do appreciate you checking it out Ivan:) all gadgets on my channel are DIY, all build info is shared am much too lazy to build for sale:)
The one I’m working on is the hybrid MKZ It’s got a 600mA current draw. I’m good with electronics and stuff. I am just not familiar with a cars communication. All I know is it uses CAN. As far as high speed low speed etc I am lost why it would use different speed for communication
Just depends on required volume and speed of data transmission. Not really an important detail. But you DO need a 4-channel oscilloscope to monitor the network activity to see if someone is "waking up" the entire network :)
My 2017 MKZ when I first got it, had an ACM firmware issue which caused the module to never sleep correctly. It will kill batteries. Pretty known issue across Fusion/Fusion Sport and MKZ. I'm not sure about MKX. All those modules are tough on batteries, especially cold.
I had a customer complain that their Cadillac randomly drains its battery. I put an amp clamp on it, went to sleep fine, few mA draw. So I go back to my truck to get a new battery and hear a noise coming from the Cady. I've got the key out, doors locked, and the radio is playing.
Dedication to your craft at its absolute finest. Ivan it is because of techs like you that makes watching you a joy

Your detective skills have greatly improved the action plan. Great video!
With these PITA wakeups I wonder if it would be beneficial to have something listening to the CANBUS(es) and logging the addresses of the transmitters to track down which module is behind the problem more easily.
My papi said son you're going to drive me to drinkin if you don't stop driving that hot rod Lincoln😁👍🇨🇦
These Lincolns definitely ain't hot rods. More like hot flash Lincoln given the age and sex of the majority of owners 😆
Very intrigued to know what it is.
You do great step by step diag never forgetting to start with the basics. 👍🏾
Wow man! Can I say genius! Master of your craft sir!
Sitting on this one for a bit......leaves still on the trees....(Greetings from NE PA.....)
Oh boy, this one is gonna be fun. Can’t wait for the solution. I too have a “parasitic draw” Ivan….known as a wife and kids in college…😂😂 Not as easy to replace those modules, need a NPR repair. Always a great ride my man.

Weird. Literally reading about load shedding in a chrysler book when this video popped up haha perfect timing!
Ivan, pretty cool! On to Part 2. Thanks for Sharing!
Ivan,
Great video and interesting case study - thank you!
Looking forward to part 2
Paul (in MA)
Hi Ivan , part 2 ASAP please, can't wait. Many thanks super interesting problem.
IVAN, AWESOME thought process and approach brother you right on modern cars to diagnose electrical problem a SCOPE is must with out it you go no where to find the problem thanks for sharing and as always learning form the best. cheeeeeeers
Ivan you scared me when you mentioned there are 30 modules on board. Cant wait to see part 2. I am gonna say its the Entertainment system?? Haha
Hey Ivan! Long time, no see! (MY fault). Man, that thing is CRAZY complicated. THIRTY modules!! Insanity! Imagine one of these in a flood - you'd end up burning it trying to diagnose it, LOL! 🤣Can't wait to see the cause of this one. 👍😎👍
Ghost in the machine. Gotta love it.
Good evening Ivan
Thanks for the new video
I wonder if it is possible to read that data that is being transferred. If so, maybe the modules ID themselves when the talk to each other. You have great troubleshooting skills, Ivan!
Thanks Ivan for the video you do great work as always 👍❤️❤️❤️
Have to love all these vehicles that have loaded up to the gills options. Really just more chances and opportunities for things to go haywire. I wonder what else is in the high speed three can? Maybe it's that module under the headliner again?
Dealer would they do anything about? Probably don’t know how to use an amp meter. 😂😂😂 good one Ivan.
What is concerning me more than anything is the fact that these cars are taking multiple hours/days to diagnose. I just don't see this fitting in with the dealership business model. It isn't likely a service writer/dealership is going to commit the time, training, equipment and expertise to properly diagnose these issues. The best part, these are NEW cars. What will they be like in the future? Great vodep!
Great video!
Can you imagine what will happen by the time they are on third owner? Talking about bypassing circuits , taped up twisted wires and unmarked toggle switches everywhere 🤔
@@dharley189 Don't be silly! They aren't going to make it to their third owner.
Thank you sir. I have a mkx with draw issue.
Is it possible to have a modern US domestic vehicle with less than 30 modules? 😂 I think we surpassed the reliability limit a long time ago… Very interesting case study, Ivan 👍
True definition of "luxury" is when your car won't start in the morning 🤣
@@PineHollowAutoDiagnostics 😂
@@PineHollowAutoDiagnostics I love it!
@@user-fn6pq9tp2g the R&D budget on aircraft is much higher, things are only fitted for a practical purpose - and they're still allowed to use "proper" solder with lead in it.
Lead free solder is one of the main causes of failure, whether it's tin whiskers or cracked joints on connectors or anything with significant thermal cycling.
The ones I see the most are Ford Focus clusters for crank no start and Fiat "Blue&Me" modules for flashing mileage and parasitic drain.
Someone mentioned in a comment how locking your vehicle can prevent some electrical draws, not sure if this is true. I think the commenter was talking specifically about Subaru's.
Looking over your shoulder, I see the XL-7, the Mystique, and the MPV. It sure does look like that Probe you featured for the Halloween Special is parked up there as well. Are you going to be doing work on it in the future? Would be interesting!
This was filmed before the Probe Halloween Special lol
@@PineHollowAutoDiagnostics I started to say, I thought you got rid of that pile long ago.
I thought Ivan was becoming a Probe Specialist. Actually that sounds kind of weird. That could easily be misinterpreted. Though, those customers could be very interesting. And the case studies would be really interesting. Part 1 - Look what I found. Part 2 - How did that get in there.
Ford Probe jokes. Glad I could use them again. I thought they were gone forever.
I am so glad that my car has 5 modules. Older cars are superior. They can sit for months and not go dead lol.
Great video Ivan!!! Super interesting.
Is it possible to narrow down the cause quicker by looking at the fuse boxes through an infrared camera? Surely the circuits that are drawing a lot of current will be obvious when contrasted with the sleeping circuits?
Once a network wakes up, many modules start talking so a lot of fuses will be "hot" 😁
Ivan... U have forgotten what you have taught us!!! 3amp draw for 10seconds. I just timed myself!! I can test 7 fuses for a voltage in 10s!!! every 1m 47s I can test 7 more fuses!!! I would have tested all the fuses in the car before you finished reading the circuit diagram, installed pinch clips and setup the scope!!! This is what you taught us! :) LOL...
My methods are constantly evolving 😉
@@PineHollowAutoDiagnostics lol. in a year u will be showing the actual data being sent on the line. I would assume that data actually says "im module xyz whats up yall?" I assume the voltage drop method would be helpful here though
Reset the BMS 1st.
Looking forward to the conclusion.
In this scenario, would it have been more useful to hook up a graphic DMM or something like a 1 channel scope in series with the battery to catch that 3A spike event rather than a regular DMM? It seemed like luck that Ivan was able to catch the event as it happened on the DMM. With something graphing, even if you missed it you could look back in history and see the spike.
In this case it seemed important to catch the 3A event since it gave a clue that a module was waking up and then going back to sleep. Otherwise you would only be chasing that constant 65mA draw. I'm looking forward to part 2 since it seems like there may be 2 separate issues. What is causing the 3A spike and then the "resting" 65mA draw.
Is there a tool that can graph in series current? 🤔
@@PineHollowAutoDiagnostics I think I've seen in previous videos of yours the Snap On Vantage can graph Amperage. Or could you use an amp clamp around the negative cable and graph that way? Maybe I'm dreaming of a magical tool that doesn't exist 😆. Forgive me. I'm not a tech. I'm an accountant who is really into cars and enjoys learning new things.
@@kv2280 yes actually the old Vantage could graph current! Wish the Pico could too. Current clamps have too much drift over time, especially at the milliamps scale. Accounting and diagnostics have some key things in common like being precise with numbers and keeping careful notes 😁👍
@@PineHollowAutoDiagnostics yes! Eric O has used his Vantage to graph current in at least couple parasitic draw cases.
and the vantage pro does internal amps. the last great scope meter snap on made. does things newer versions can’t, and has a long long data memory, so perfect for a job like battery draw. wish somebody still made a tool like the original vantage or the vantage pro. a real time graphing multimeter is a very handy thing. i love the vantage pro so much that i finally found two of them.
Just acquired grandfather’s 2016 3.7L MKX, has only 12,000 miles. Put new battery, air filters etc, drove home 750 miles. Week later battery draining parked overnight. Unplugged a AAA device from port under steering column thinking that maybe cause. Now battery holding for days but on last road-trip and since last jumpstart the Nav and infotainment have gone black? Car driving fine just missing all the tech
I'm about 9 mins in and wondering, if ambient temp was cold enough, one couldn't watch the fuse box with an IR camera when the amps spiked up and get an idea which fuse was heating up then see which modules were powered on that fuse. Together with your scoping the different networks might narrow it down to a single, or very few, modules really quickly
Ivan: What is the hardware and software you use for the oscilloscope on your computer. Very cool! Love your videos! Keep it up!!!
Would thermal camera at the fuse boxes lead to the culprit network?
Unlikely...
I think my 2017 lincoln mkx is having same issue.. replaced battery, battery has been checked, there seems to be a draw someplace.. I've noticed when I turn it off and walk away, internal lights dim and go out, but my radio knob back lights stay on.. with key fob in house.. however, when I lock the car, the backlights turn off. I'm thinking this may be the draw and may be draining the battery. my dealer charges 200 per hour so not sure if I want to take it there of if they can even fix it. in meantime I bought a NOCO Boost Plus and will keep it with the car in case it won't start.. and will try locking the car each night to see if that fixes the issue.
1 min 40 seconds = 100 seconds or 100,000msec. Not a coincidence!
Is it possible to read the activity? On a common network each module must have a unique identifier.
I guess if you can decode the signal 👍
I recently bought a scope for can wiring diagnosis I just wonder where do you hook up your leads to? Most can networks have + and -, does it matter which one you hook up to?
Great video. Awesome tutorial so far. 👍
Just curious is the security system on the high-speed Network almost like it's trying to set the security system or something a very interesting
Looks a new model to be giving trouble. Isolating the networks has done the business. Very time consuming exercise but seems to be showing results. 3 amps is a bit over the top. Too troublesome for a dealer, especially with the extended timeframe involved. You'll soon be crowned 👑 of the parasitic draw division.
Oh no, I hope that isn't the same Probe from Halloween I see in the background. Though, what are the chances it's a different one. If it is a different one, Ivan must have seen a business opportunity specializing in 25 year old Ford Probes that surprisingly no one else saw.
HS3 has mostly audio and user interface devices, including instrument cluster and telemetrics. I'm gonna throw a wild guess at either the cd player or FDIM. lol
I'm guessing a stuck wiper motor trying to park. 😁
@@murkywaters7185 like the 68 Corvette? 😁
The cause of this is the "welcome" feature on your Lincoln (when your car seems to wake up once you get close enough to it with your key fob). If your Lincoln is dying overnight it's because you're parking your car close to the house or in the garage, and keeping your keys in a spot close enough to initiate the "welcome" feature, door never opens, allowing it to fade out, and then once off it re initiates the same feature and same cycle over and over until your battery completely dies....you're welcome. And if you actually watched this whole video ... 🤦 You'll never get that time back
My keyfob hasn't been working for a year though. 😅 My battery keeps draining everyday now. Even with good battery. 😅
Fascinating! You amaze me!
I have a 2009 mks when the temperature outside raises or my defrost is on my electrical components such as my radio/navigation and climate controls go out. it also tells me that all of my doors are open. I’ve checked battery fuses altanater im lost as to what i need to check next
Thanks Ivan.🙂
for monitoring these stubborn parasitic draws Ivan, you might find my GADGETS#168 interesting
Interesting gadget indeed v=BwexDcEiKz0
Just watched the #168 video... That's AMAZING! Can I buy one of your parasitic loggers? 🙂
@@PineHollowAutoDiagnostics I do appreciate you checking it out Ivan:)
all gadgets on my channel are DIY, all build info is shared
am much too lazy to build for sale:)
If it was me, I'd be reaching for the thermal camera. I'm sure that's enough power to show up.
The one I’m working on is the hybrid MKZ It’s got a 600mA current draw. I’m good with electronics and stuff. I am just not familiar with a cars communication. All I know is it uses CAN. As far as high speed low speed etc I am lost why it would use different speed for communication
Just depends on required volume and speed of data transmission. Not really an important detail. But you DO need a 4-channel oscilloscope to monitor the network activity to see if someone is "waking up" the entire network :)
How about a CD changer powering up, stowed in the rear storage bay of that vehicle???
Faulty alternator, Corrosion , Poor ground, Power Trunk Module... what modules are on the High speed 3 can bus ?
Ivan,
I noticed you did not use a BOB at the diag connecter. Did you have any concerns?
BOB draws some current... Didn't want the extra variable lol
Excellent!! Can't wait for part 2. Thank you
My 2017 MKZ when I first got it, had an ACM firmware issue which caused the module to never sleep correctly. It will kill batteries. Pretty known issue across Fusion/Fusion Sport and MKZ. I'm not sure about MKX. All those modules are tough on batteries, especially cold.
i say to myself 100 seconds and dammit Ivan part 2 again 😮lol😉
I'm just asking. Does the thing going wrong stay on long enough to heat up? Could you have pinpoint the problem with a infrared camera in this case?
thank you professor ivan
I had a customer complain that their Cadillac randomly drains its battery. I put an amp clamp on it, went to sleep fine, few mA draw. So I go back to my truck to get a new battery and hear a noise coming from the Cady. I've got the key out, doors locked, and the radio is playing.
Is that a Ford Probe in the background there??
you could use the 8 channel scope on a diagnosis like this !!!
Bernie would 😅
if you get an 8 channel scope, you too will have better troubleshooting in your bays 😂
Use the other 4 for cam and crank signals? 👍😅
Bernie would probably use all 8 for a parasitic draw, too! The man's skills amaze me!
4:53 the way you said that made me laugh
Unable to find a wiring diagram for my Lincoln continental 2017 are there other models that are similar or can someone help me with an idea
