- What is this? A Toyota that's acting like a Chrysler?!?
Occasionally, with no rhyme or reason, this 2007 Toyota Camry throws a fit and the instrument cluster goes bizzerk.
But is it the cluster's fault?
We dive in and definitively prove the fault before loading up the parts sniper rifle :)
Enjoy!
Ivan
I was an old school mechanic, I never got into the computerized stuff... I never would have thought an ABS module could corrupt the data enough to mess with the gauge cluster. It's awesome to watch you further diagnose it with a breakout box to further explain to your viewers what is happening and why replacing that module would fix it.
This is definitely one of the better channels I've seen. Thank you.
I am unfortunately disabled, so I I fix cars vicariously through watching mechanics do it on UA-cam. And I still get to learn stuff which is even more awesome.
Thanks for the message Dave!
@@PineHollowAutoDiagnostics not a problem! I am definitely a fan of the channel, certainly keep up the good work :-)
I always love the "tear it apart" bonus footage part of these videos!
The 2 pins are for the pump at the back, but i guess you figured that out by now.😉
Hi Dan! Yeah it became obvious when I looked at it a bit haha
HERE'S WHAT I DID: 2 months ago it happened to me. Same screwy dash, warm a/c. Got another ABS module from auto junker, and it didn't work either. Lost $200.00 because they wouldn't take it back. Bumped into Module Masters on Google and sent it to them for repair. They fixed it for $200.00 +, and did a good job. Just slapped it back on and it worked. Side note: car ran pretty rough for about a week. Car had to relearn itself, but it's fine now. You can drive it with it messed up. You have to put a G.P.S. app on your phone to tell you your speed....hey it works. Big pain in the butt for several months. Went through 3 mechanics. They all said go to the dealer. Also you don't have to program the module, just bolt it back on.
I’m trying to get the car from Ohio to Georgia do you think it’s a good idea
Which place did you have it fixed at?
From the U0073 (Bus Off) it's most certainly the ABS module itself, which has gone nuts. So each ECU has it's own TEC (Transmission error counter) which gets increased for every broken transmission or any garbage send out by it. After surpassing a certain value the ECU enters bus-off mode and forced to shut down and not participate on the CAN bus anymore, to protect the network from distracting and stacked messages, like in this case the ABS module. These cause the cluster to go crazy until the ECU enters bus-off. In some cases ECUs try to recover from bus-off, as e.g. the ABS is safety related. Often times vehicles enter limp-home but in others the module seems to be fine after being restarted for a few moments until it's acting up again.
Single shot Ivan, no magazine required. Unusual fault.
Thanks for sharing.
You ABSolutely nailed this one Ivan. Nice diagnosis and teardown!
Lol thanks John!
I had the same issue in my 2009 Camry. Followed the instructions and it worked like a charm. Thank you!
Just came across this exact issue on a customer's vehicle. Didn't even realize that you could take apart the ABS modulator like that, saves a lot of time not having to bleed the brakes. I'll be giving this a try when the parts arrive.
You saved a lot of time for me and my friend. I have exact same scenario with 07 camry here and I just replaced the module and it’s fixed the problem, so thank you so much👍
I bought a camry 07 w 175k... after 100 miles in I noticed the abs and brake light as discussed, I will be switching out the abs module soon
Lol make sure u buy oem not aftermarket
Do we have to program it after fixing the module
Have same on 08 Camry. Looking at waveforms, it shows that this is a connection issue, as the voltage difference (good part of signal) is being lost due to intermittent connectivity issue (dropouts.) I read on Toyota forums that someone fixed this by pushing the connector towards driver side and wedging hard plastic between housing and connector. This makes sense as if there is a failure of an electronic part that usually is not intermittent. It is all or none. So, the randomness of it happening, with the exact same behavior, actually points more heavily towards connectivity. I did not see if you had a live feed of "good" wheel speed reading while moving with display dancing (that's what I call it.) If the wheel sensors are dropping, then that could lend more info to troubleshooting. I bit the bullet and sprayed the removed ABS module with electronic contact cleaner all throughout but only heard of this forced position fix yesterday so have not tried it. The cleaner did not provide results. I am thinking of doing what I do for other electronic connectors and that is stick a tiny screwdriver blade into pins and slightly "misalign" them so that there is more forced contact on the pin.
THIS! I was getting ready to trudge through a self-service salvage yard in the 103-degree heat for the module when I saw your suggestion. What the hell, right? The cluster was acting up. I put in the wedge. It stopped. I took out the wedge. It acted up. I did it 5 times and it worked everytime. I recommend Tubers try your fix first before investing time and money.
Got here after watching you help out Eric O. at South Main Auto with that Hyundai Tuscon. What an awesome diagnosis and an amazing failure mode on the Tuscon. Knew at that moment I'd be subscribed to PHAD.
Keep up the good work, and keep the videos coming. I'll quote Scotty to others: "Ring that bell!"
Welcome to the channel! Ah the Hyundai Tucson case study that started it all...that was an amazing case study haha
It’s funny, I came across this video when my car is having almost this exact same issue. Love that you go so in depth with it. The biggest difference is that I can’t talk to the ECM/TCM when the ABS goes haywire. I have the DTC C1301 stored and that’s it
It's a common problem on that generation of Camry. The last one I did, in addition to the crazy dash cluster, the A/C wasn't working. I unplugged the ABS module and plugged it back in. It temporarily got everything to work again. I picked up a refurbished module, problem solved.
Hi Ivan those two prongs inside the pump housing are for the brake pressure sensor the prongs clip into the circuit board And tell the circuit board when full brake pressure is applied hence activating the ABS. I think you should look at the old circuit board with a magnifying glass attached to your computerAnd zoom in you will probably see broken or cracked soldered joints. The Bosch units suffer from this problem
Only on ur channel do we get to see the inside of a ABS module, thx buddy
Contacts in the middle of the unit are for the brake pressure sensor. Greetings from Norway!
Dorin David he was pointing at the two prongs, thats pump motor, pressure sensor usually have tiny 4 pins
Would be interesting to use the subtraction feature of the scope. Since those are differential signals, subtract them and see if the result looks good. It's a way to pick up glitches that are only on one side of the bus.
Had a CD player once that killed the CAN bus and the ABS was on the same bus and so it didn't work. The CD player was working fine but it was difficult to tell that it's communication with the rest of the car was dead. GM had put safety equipment on the same bus as the entertainment system?! Yes they had.
Hi Ivan!! I agree with you. My 1994 Chevy K1500 has the pitiful Rear wheel only ABS system on it. It hasn't worked for years and I don't miss it. Maybe one day when I have nothing better to do I'll dig in and test it, but after driving lots of other vehicles that never had an ABS system I kinda doubt it. Keep up the good work. Love the Vids! Thanx for what you do.
is it just me or did you see it flake out when you were disconnecting it right before the plug came out?
Hi Ivan, Inside the ABS, those two spiked things, are the connectors for the ABS pump motor.
Mr Google knows everything. Great video on using common sense and getting job done.
Personally I have mixed feelings about abs, however I still think the pros outweigh the cons, good video Ivan thanks for taking the time to share it with us
Hey Ivan I just had the exact same issue with the cluster . Turned out to be the abs module . The ac also stopped working too . I changed the abs module and boom 💥 it was fixed
But in changing out the module could you have inadvertently just provided a more snug fit for the connectors, and not really had to change the part as it is not actually bad, but just having intermittent connection issue. I suspect the issue will crop up again in the future.
@@SomnoNaut this was over 3 years ago and no issues at all . Also when the abs module was plugged in the issues arose . When I unplugged the abs module all good .
@@joehomanick Right, the connector pin/socket connection could have been the interruption causing the issue is all I was trying to bring up. That can only be tested by using the same module but mucking with the pins and sockets and seeing if they make better connection. The one you replaced it with could have just been tighter to begin with.
Same problem with mine 2007 Toyota Camry 2.4v and Yes it is the ABS Module 👍 Perfect diagnosis 👌
The case of the crazy Camry cluster conundrum! There was a company that refurbished the ABS module for my 99 Passat years ago.
I had a similar problem in Australia with a Camry Grande model. I replaced the factory navigation stereo and one of the wires was grounded that caused the same issues as yours. It was only when I double checked and found the wire and also managed to get some wiring diagrams that show some sort of speedo connection to the factory stereo for the navigation system.
When it is intermittent, I would have re-flow all the solder points and replace those electrolytic caps. temperature can cause intermittent connections.
Upon disconnecting ABS module in a Toyota, Transmission will have a higher RPM shift points due to the lack of wheel speed feedback
Good fix Ivan 👍
Ivan what happened to the tap on it test. When you went outside and unplugged it, the scope went nuts when you touched it
Great point! Tap test is a good one :)
Yes I felt the same way. I was shouting at Ivan thru the sceen "Do a tap test! Do a wiggle test! Try just cycling the connector!" Should always do those tests. There were several electrolytic capacitors on that board - those always fail over time.
God bless
Paul
@@Paul1958R Caps fail dead or alive, not intermittently. I find this with TV especially.
I use UA-cam a lot for research. :) Great job Ivan.
No way. Scotty Kilmer says Toyotas never need to be repaired. Lol
probably the first problem after 12 years which is nothing major. It still was driving, even tho the cluster was screwed up a little.
Not sure what your point is. This is a 12 year old Toyota with 141K on it that had a minor problem. I'd be very happy with that kind of reliability.
@@nickv4073 ya me 2 he'd want to stop acting cocky
It was a joke for people that watch Scotty Kilmers channel. Relax
@@biggh632 I watch Scotty. Still don't see the joke. I never heard him say Toyota's never need to be repaired. Only that they are well built and reliable.
Those two long pins that were coming out of the abs valve block do actually go all the way through. They take power from the board to the pump motor. Those pins are power and ground for the motor.
Excellent video. My ex wife has 07 Camry, just exact same like in the video. If she says the cluster acts up and ABS lights up. I'll know what to do lol. Sniper rifle at that module lol. 😆😆
Thank you for the video. Had exact same issue and this worked. Thankfully I had a spare car with a good abs module.
I'm with some of the others, Ivan. I would have definitely checked that BIG electrolytic cap for correct ufarad value. Great job, once again. I know it breaks your heart to have to change parts. :)
the 2 contacts may be for bidirectional control of the pump motor to bleed exct
I worked on a VW Golf once that done that, in desperation I disconnected the battery, reconnected it and it cured it...Fred.
Had a MK1 Focus a few years back in the UK. Cluster would go nuts at least once on every trip. Engine would also cut out. Pure chance I found a post online advising that the speedo sender unit screwed into the gear box was the culprit, I was very sceptical but had run out of ideas, so I replaced the sender. Car ran like a dream for the next 3 years til I traded it in. Would never have suspected the resolution to that problem.
Interesting. My first suspicion with a MK1 Focus would have been water ingress and moisture build up behind the dashboard. My mate had an 02 reg where he had all sorts of crazy gremlins and a lot of the connectors were full of green crusties. We just deleted the connectors and soldered a spliced all the loom together. Cured most of them. He wrote the car off a few years later in an accident. Not bad for a few hours work.
The bit size is E4, not E5. External Torx socket
I have seen a few issues with ABS modules, never identified any internal faults visually.
Best solution, swap them out as you have done.
maybe the tach. was saying "help me" in morse code lol
Hey Ivan do you sell Pine Hollow Auto Diagnostic t-shirts just curious
Working on it!
I had that happen with my 2007 Camry when my alternator died and depleted the battery while driving. Surprisingly it still drove fine so limp mode had some pretty well thought-out parameters.
Might want to let the owner drive for a week or so to be sure. What did the ABS connector on both the wiring and module sides look like? Networks can be fussy things. Low voltage and near zero current. The signal is the only clue to the problem. If the connector had pass through wiring for the network, it could have been jumpered and driven to see if the problem went away. I was thinking while it ran good, what happens when you push on the brake pedal? What did the ABS do when the system was running normally, and you forced it into an ABS stop? How well was it working when the system was good? Just throwing some ideas out here. Sometimes an intermittent can be forced into showing itself, like rough roads, railroad tracks, left or right turns, but you were lucky it appeared right away. Nice diag using the Pico! Hope the replacement module works for a long time.
Ivan ,why didn't you do a simple look at the wire harnesses for bare or pinched wire.It appears like a loose or intermittent grounding wire./ IS THAT POSSIBLE? I'M OLD SCHOOL so that's my first go to on intermittent gauges ,lights,blown fuses,etc.
Odd issue, glad you figured it out.
Pretty common over here on the '40 series' Camry's Ivan. Wreckers here are ridiculous here on them(can buy a whole damaged car for the price they want for the ABS Module Assy usually). Don't see Brown Trim that often over here!
I want some of that grey adhesive. That looks like some good stuff!
Thanks for the bonus footage.
I've seen similar weird behavior when there is no solid connection between the battery negative and the engine and/or when connection was somehow corroded or removed between the engine and the chassis. A lot of times they would complain about hard to move AT shifter linkage.
I always check to make sure there is a solid connection from the battery negative to the engine. It's important to visually inspect the wires because the meter won't always show it.
I have this same problem rn on my 2007 toyota camry except my ac and radio cut off a few times when it goes berserk. After it does it 3 or more times my car refused to go forward and completely shut off on me while I was exiting the highway and left me a check engine light. Turning on and off tue car it let me go home but now I gotta see what this lights for and if it's multiple problems 😭
I like your videos and how you approach things from the practical side. What I don’t like though is your obvious disregard for all the safety systems in modern vehicles. It starts with to not buckle up on public roads and ends with permanently disabling ABS. Since this appears to be legal or don’t care in your state you are probably allowed to do this but I still think this is a bad attitude which lowers the safety on the road.
Be sure to forward this to Scotty for proof that Toyotas DO break eventually. lol . But seriously, how did you get away with not having to do a reflash?
Because it's not a GM product. 😁
i have an 07 hybrid doing same but mine is worse, i had a short from a minor accident front right end, i fixed short but problem still there,gonna try this
I was hoping you would open the abs and find out the microscopic componets inside. lol
hello. I am in Beirut Lebanon. I have Toyota Camry SE 2007. I had this very same problem exactly on 04May2023. I need the ABS module and I cannot find it in Lebanon. hard to find.
Remove the module, spray with contact cleaner, reinstall. Some mysterious fixes by taking it apart and putting it back together then it works if lucky. No clue why but works sometimes, worth a try.
8pm Friday night hear in the uk . i have a cold beer and this pops up happy days
Awesome. Enjoy, Simon! :)
That is awesome do u work in Louisiana hard to find a good person to fix cars with out them taking your money thanks for sharing many blessings
Hi Homemade - I know exactly what you mean. Most mechanics are just ruthless, cold people with absolutely no morals or ethics. As with everything, thankfully it doesn't apply to ALL mechanics! I will forever be grateful that God gave me my husband of almost 40 years for many reasons. One of those reasons on the lower end of the scale is that there is nothing my man can't fix and I mean nothing.
Being it did not change when you unplug it maybe the module was shutting down changing to a default strategy and then not disrupting the network instead of coming back online like you thought. I know the lights came on but maybe there was enough running that kept the lights off so you unplugged it turn the lights on.
You know it's getting real when BOB shows up at the party! LMAO Great video on a rare Toyota problem Ivan
Battery operated buddy?
@@miguelare3 break out box
Toyota has TSB for that. What we do ? There is update,we do update first which is not help than replace abs module with abs bump. Than you have to do air bleeding,resets memory,zero calibration and couple more things. TSB covers 10 years 150.000 mile which ever comes first.
do you have to program it ?
is the number on module have to be matched? please i need an answer,,, thank you
You would never get away with the "don't pay until repair verified" philosophy in my neighborhood. The customer would simply never come back.
You should move, that's how I've always done business.
@@strtngfrsh In small town America, people trust each other. I'm in rural south central Pennsylvania. Farmers around here put vegetables in an unmanned stand out by the road with just a box or jar for customers to put their money in.
The circuit board looks the same like on a VP30 Diesel FIP (bond soldering I think is the right therm) and the VP30 pumps also go bad cause the pump module gets bad and causes some transistor to burn.
So, what do I do if after I unplug it and take it for a drive and still see the gauges act funny? What then is the problem?
Those two long pins at the bottom of the module I think we’re the problem. You should look at the bad module to see if the green crusties aren’t inside where those two pins connect into the module. I usually use UA-cam or the internet to see if someone else had a similar problem or check for TSBs on what I’m working on. Nice Job Ivan. You and Eric are my two fav. Diagnosticians. Keep them videos coming.👍
Thank you good job I have the same problem thank you
7:00 had a 17 ridgeline come in and it had a rear diff temp sensor code, i could not get it to recode but the customer always got it to do it, what was the fix on that? differential replacement! it is NOT serviceable at this time(although it is written up that way) so what do you do? much like your situation except i couldnt get it to do it! (frustrating!! why cant it just stay broken??) "i cant duplicate it but the customer can, what would you like for me to do on this warranty job?" lol! great content Ivan!! thats for that snippet! pinpointed troubleshooting for sure!

If they used fibre-optic....light doesnt cancel itself out, might be something for them to move forward on
Jusb1066
The fix is to stop using one serial bus for everything.
One wire shorted and everything stops dead, not what i would call clever.
Not sure about optical fiber, i think clashing could still happen when one device ignores the protocol of the system.
The abs module ignored everything.
@@zx8401ztv yes it can ignore, but it cant swamp out the network, same as we get thousands of calls down one fibre
@@jusb1066 Mercedes BMW and Audi have been using plastic optical fibre for about 15 -20 years. Mainly found in Euros.
@@jusb1066 It can still go noisy and corrupt the network. You could have subnets for everything but that would defeat the purpose of using a network in the first place and drive up the cost.

I watched this again till the end and saw the bonus video. I have to ask, how in the world can there be shops on Ebay offer to rebuild your own module, if the only way to get to the components to rebuild it is to break it open? This makes no sense. There must be a way to get the circuit board out of the module other than prying it open.
Have the same problem at the moment
This just happened to me today…. Anyway of changing the abs module without messing with the brake lines themselves? I havent actually looked yet because it happened on the way to work. Appreciate the video!
ya watch the video...just replace the electrical part, very easy :)
I have the exact same problem and no codes come on..
If I had the time to try a simple fix then I would replace that blue electrolytic capacitor and see if that cured it. They are really cheap and easy to replace and VERY prone to failure. That car has 141,xxx miles. Heat and time will ultimately destroy electronic components, especially electrolytic caps.

Thank you so much for the helpful video. Do you guys know how to get a used ABS for camery 2007 in excellent condition and at a good price? I ordered one online but it didn't work at all.
Why didn't you have to program the new module? And how do you know when you need to program a new module and when you don't?
I have a 2009 Camry with the same problem. It started with the symptoms shown on this video but now I also have issues with the headlights (doesn’t indicate high beam on dash) & when the gauges go, so does the a/c. Is it likely that there are other modules that need to be replaced or do you think everything goes back to the ABS module? Thanks
Thank you Great video . Thumbs up

Not bad..12 yo car and a module fails. I dont care what anyone says...Toyota makes very reliable cars and trucks. BTW...Great diagnosis. You are one very clever man Ivan.
Well... my 2002 crv has the original abs module so... Hondoo won this time
@@zoneb609 So far anyway, that is something that has not failed on any Toyota we have owned. 2004 Corolla we had...Black Box failed...replaced under warranty. Fuel pump failed...replace under warranty. After that, nothing really failed after that. RAV 4 and Tacoma...nothing has failed. Seems lile the quality got even better on newer Toyotas we have.
FYI. I'm not sure why but i have seen aftermarket scan tools cause Toyotas to set that U0073 code. I never got to the bottom of why.
