Chevy / GMC Truck: Crank No Start No Communication With FPCM
Вставка
- Опубліковано 28 вер 2024
- Come along with Eric O. at the SMA shop as he has a look at this 2009 Chevrolet 1500 5.3 that was towed in as a crank no start. It has a code stored in it U0109 for "loss of communication with fuel pump control module." You can follow along with Eric O. as he brings you along and diagnosis the FPCM. We also get to use our J2534 Interface device and do some programming.

When I retired I has 2 ASE Master certificates and every certifications Ford offered, and more and I'm saying this man is GOOD, or as a friend says "good at it!" Anybody in his area needs to take their problems to him. As to prices, people need to understand that it takes a lot to operate a business like his. The money for tools alone is high and a good scanner alone can cost 10k, or more plus there' are more and more tools needed including special tools that may be needed to work on a certain brand of vehicle. On top of that the overhead in NY is astronomical. A good tech like this man is worth top dollar.
You better believe he is good. Even car companies send their non-functs to him. He is so good I wish he lived near me. Why? Because he is honest. I am sure he has failures but not sure I have seen that come up. His car probably runs like crap that is the way it works
The shop rental alone will keep you up at night not to mention heat electricity etc.
Especially knowing he is honest and up front about it. It’s sad to say that that is getting more rare.
Knewa dude that has 6 of those same "doublecerts"! Tip of the cap sir.
Wow, watching you diagnose things is just awesome. It's not just the diagnosis, but the fact that you do it quickly, and confirm it 100%. Amazing. Thanks for educating and informing us. Most of all though, thanks for sharing this!
If I ran a shop, the "waiting room" would have a television streaming South Main Auto nonstop; first off, it'd help give the customer some impartial insight regarding the extent of a given repair. That, and when I was under the car watching the same video, they'd be less likely to notice🤫
you probably dont give a damn but does someone know a trick to get back into an instagram account..?
I was stupid lost the account password. I appreciate any help you can give me!
@Mauricio Alfonso Instablaster :)
@Chris Bronson thanks for your reply. I found the site through google and im waiting for the hacking stuff atm.
Takes a while so I will reply here later when my account password hopefully is recovered.
@Chris Bronson it did the trick and I now got access to my account again. Im so happy:D
Thank you so much you saved my account !
The first 21 mins of this U0109 crank no start diagnostics is on point, After that Eric overworked himself. I believe the easier way to check if the fuel pump is the issue would have been to jump the pins for the fuel pump to power and ground on the same harness, Without plugging the harness back into the FPCM. If the fuse pops the problem is either the fuel pump or a short in the wires going to the pump, If the fuse does not pop then the problem is a internal short in the FPCM.
Great job with the videos keep them coming.
So sweet of your wife to tell that she has a good life with you Eric O. It warmed my heart :-)
I don’t know if you are still following these comments or whether this was already explained somewhere in the 564 comments, but circuit breakers are not ideal substitutes for fuses, as you discovered, because thermal circuit breakers typically take much longer to trip than a fuse, especially in more marginal overloads (for example, drawing 30-50A on a 20A circuit) - even longer still in dead shorts if they do not also include a magnetic trip element. It takes time to heat the bimetallic spring in a thermal circuit breaker, much longer than it takes to melt the thin wire or metal strip in a sacrificial fuse. This extra time to clear the circuit means that wiring and circuit board traces, etc., can get very hot before the breaker trips even though their operating load ratings are identical...and sometimes they will wind up failing before the breaker can finally do its job. That is part of the reason, costs aside, why fuses are used extensively in vehicles since the wiring harnesses are usually of rather light gauge and not really suited to handling extended overloads without overheating. Ideally, instead of using resettable thermal circuit breakers your kit manufacturer ought to redesign to use resettable *electronic* circuit breakers that better mimic the time versus load characteristics of the fuse you are substituting it for as it would then afford the same degree of protection.
Another informative video. As the owner of an 05 Silverado, I appreciate this one personally. Thanks for all the detail in troubleshooting that you provide for us all, as well as the needed reprogramming of the new control module.
Love how sealed the module was conseidering its location ... glad they dont make aircrafts
👍
I can say that it's a smell you'll never forget. I have gotten quite a few electronic items, that "Quit working" once I take a whiff of it, and smell that.. the diagnosis is pretty easy.
wow, talking about same thing, Ivan did the same thing. he put silicone on the back of the module to seal it from moisture and road film etc. he applied sealant on the connections to further seal the connections to the module.
@ Eric O. and Josh Benny Hello, Im needing to do something like this for the blind zone alert modules on vehicle. How did this work out? Did he put silicone directly on the board? I've seen some apply nail polish to seal would this maybe work sir this type of application? What kind of sealant would be used on the connections to seal? Just a novice trying to keep vehicle on the road. I appreciate any and all help...Thank you.
As a retired mechanic of 45 years i worked on construction equipment and municipal equipment in N.J i would of loved to work with you you are a smart Son of a gun but i really think Misses O is your mentor!😁
Let's all pitch in together and get south main auto a 4K camera and their own internet fiber connection.
Not just for weekly videos...
But also as a live streaming shop-cam
Eric please do a video explaining pcm up dates and software programming of newer vehicles. I have no idea what is involved with all that. What happens if you do not do software updates? Do you have to do them for the car to run right...??? Please please do a video. You are a very good mechanic and I know you know your stuff with this new technology, and old! You are the best of both worlds. So please help an old school guy like myself to understand these things. I am a mechanic myself but have never gotten involved with these high tech things and I find myself more and more falling behind!
Astonishing that they put that module where they did considering people use these trucks to tow and launch boats in salt water!
The same thing came to my mind boat ramps.
Great spot for a fuel control module, thanks gm - I had the same issue with my spare several years ago I needed it out, spent quite awhile messing with it but luckily got it down. I decided that with that setup you don’t really have a spare anyway that you could access on the side of the road so it has lived in my garage ever since - it is a giant rust magnet under there
if you put two post Jack's to Hold the tire up quite often you can push that safety latch over and get the tire down with no issues 70% of the time. I am in New Jersey so I know how much of a pain in the butt those tires are to get down.. you have to use a long flat head screwdriver or a slim pry bar to push that latch over with a little bit of effort and persuasion
Have been watching pretty regularly, but the old stuff is always really good. I think both Eric and Mrs O are lucky.
Great job. I like your diagnosis procedures.
As another auto professional, I would be interested in the time you charged for the entire job.
Hello Eric;I went through the same thing with my Dodge neon just before Christmas. A fault of the PCM necessitated a
replacement because the car wouldn't pass the emission test. I had to
pay a mobile guy to
program the PCM once I got it replaced. Yes the newer vehicles can be a real pain to work on so I see where you're coming from. Anyway keep up the good work and thanks for your informative video.
Next up for engineers, a spare tire powered hoist to raise and lower the tire and also maintain proper air pressure for readiness at all times, complete with it's own control module of course. These should come on line soon after they unvail the blinker fluid control modules.
arciefan veil*
If I watched anyone else do this I'd be so lost but you do such a good job of explaining it so we can understand it and I've never really had any clue with electrical diagnosis
Gotta love saltwater + electronics + metal. Nothing like upstate NY. Good job on GM for putting over-complicated electronics in a heavy abuse location on a vehicle meant for abuse situations. There's gotta be one GM engineer who's somewhere in the corporate world going, "I told you fools that location was a terrible idea! Remember that meeting we had in conference room 302 back in 2008?? I told you fools. I told you."
Our world needs more people to take a step back and think simply and logically occasionally.
...and after listening to that engineer bitch and moan, he walked to the accounting office and said..."man we're selling fuel pump modules like hot Cakes! I told you! dumbass engineers..."
You might be misunderstanding the situation though. It's the newer better GM retirement benefits package. Instead of boos, that guy has been promoted and they'll be putting all the brains in as many boxes as they can dream up and all of them will be just an inch or two short on enough sealant to actually work. The plan is clearly working well.
You know just thinking what about on the boat ramp wow that would kill it fast.
Greg Paine the TCM in a pt cruiser is put in the wheel well behind the front bumper. It may be silicone potted. But that didn't stop it from rotting out.
GM is a parts company at this point lol
Not downing you at all Mr o but I would have cut that cable and got that tire out of my way first thing and unplugged the fuel pump then tested I try to isolate things if I can but you are still the man thanks for the videos I'm a 30 year technician myself and still learn everyday and you are a good teacher always know never assume that's how I was taught 30 years ago
One of many of your videos that I love..Very educational Eric always teaching us something..
Like the amp clamp trick to see where the short may be coming from,need to write that down.
Great video. Try using an Ohm meter to check the pump for a short circuit.
lol
the fuse is "still" blown.......I hate it when they don't unblow
I watched Ivan do one and he put a bead of silicone around the edge of the new one to help keep water out. Great video.
great! Now I'm going to go out and try to crank down the spare on my Xterra. I don't think it's been cranked down the 12 years I've owned it
Mrs O cooking abilities are top notch, heating soup from a can in microwave, peanut butter and jelly triple layer, she's going all out for your lunch.
But just remember she went all out for you.
Great video Eric, GM's famous spare tire holder that's why I got mine in the bed had to cut it out.
Another great fix. These electronic modules are exactly what I try to stay away from by keeping my old truck. God knows what I'll do when it finally dies on me.
Watching a video from your channel whilst you are watching a video from your channel. WOAH!! *Insert Bill and Ted Gif*
Besides you and I do people know who Bill and Ted are??
Excellent!!!
EXCELLENT !
If you really know who Bill and Ted are, what number am I thinking of? :)
jix177 69 dude!!!!
That remove and replace vs reprogramming got me one time too. Took me about 10 mins to figure out why it kept giving me dumb warnings. I got it whooped though. Good to see other techs that don’t guess are out there. Love your videos. Keep up the great diag work
Thanks for this Mr. O, every video you put up of burned up modules and electronicals makes me want to forget buying anything newer than 25 years old. Control modules, reprogramming, how about relays and fuse boxes? Sounds like just more reasons for the manufacturer to make more money with proprietary stuff by locking us into dealership repairs.
With great technology comes great responsibility
Often power driver circuits are controlled using FETs, especially when it's an on/off or PWM type control. FETs tend to fail shorted, which I suspect is what you are seeing here. The Fuel control circuit probably uses FETs to power the fuel pump, and those likely failed shorted causing the excessive current and blown fuses.
"I do have it good, 'cos I married you". Now that's nice!
Greg Monaghan She just said that cause she was on camera😂😂
Smart too. 😉
She's a keeper, aint she?
This guy is a pretty sharp cookie, knows his stuff.
Wonder how many GM truck owners will try to get their spare tire down this weekend?
Haha good luck :)
Thomas Niner I have been soaking my spare tire safety latch with Fluid Film. Maybe it will operate when I need it, maybe not.
It is a 2008
Me... Mine really is just a decoration. Doesn't even have air in it haha.
Mine is a 2002 and it actually comes down i don't think it has the safety latch or it is broken.
You say you're no electrician but you certainly are. Great explanation, thanks for the upload.
engineers should be a mechanic for a minimum of two years before designing vehicles !!!!
Yes
I agree 100%
ABSOLUTELY!!!! I’ve always said that too!!
@Robert Slackware Ha you're damn right Datsun/Nissan are engineering quality control i had three prior cars in my family from Nissan 1982 Datsun Sentra/1992 Nissan Sentra/2002 Infiniti I35 all with at least 250,000 to 500,000 Miles on the odometers' and now respectively 2016 Nissan Rogue and 2016 Nissan Murano the level of engineering and design their products is bar none. As a independent mechanic they are sometimes a pain in but to work on. It's rare that something major to go wrong (Knock on wood) well at least to me. He'll I'm trying to get a hold of a 1970-73 Zed as a project for. my self.
that will cost gm alot of money.
Ivan did one the other day and added silicone to the back of the module. Another great video.
Love the snow on the truck, 111.2, Fahrenheit.in Sydney as I watch this
Weird to watch a video 6 years later. Your new videos highlight the Rona loss of smell. Funny how things change, not salt corrosion but other things.
Eric,
That "Black Thing" is a Surface Mount IC. If you could get the chip it's an easy repair for an electronics tech. I know this was three years ago. I have had to make some similar repairs for my dad and brother's trucks. The key is being able to get the IC chip but a lot of them are pretty readily available. The burn marks are a sure indication water got underneath that chip and shorted the leads that are soldered to the circuit board. Just an FYI.
JohnnyG
40:04 "Garbage in garbage out, that's all i know" lol love it.
Nice work. Not many people who can diagnose electrical problems. I would have called the customer to see if he wanted his spare cut free. I didn't think mine would come down either but to my surprise, it worked. The rim was rusted out and junk and the tire was 13 years old so I wouldn't use it anyway.
She is very good to you and I am sure when you are off camera you are a teddy bear.
ERIC, JUST DISCOVERED YOUR VIDEOS THIS VIDEO MAKES ME THINK IF MY 1991 CHEVY G20 5.7I TBI HAS A FUEL PUMP MODULE ALSO.
Thanks for another great video. I wanted to report that my 2015 Chevrolet 1500 pickup has a simpler spare tire mechanism, with no secondary latch, which I discovered when I went to see if it still worked after watching this video. The spare tire came down, and went back up. the fuel pump module is still in the same place above the spare tire
Yeah they did away with it in the later years
I start my day with cars and coffee on velocity,and South main auto
Must not work for a living
Just fyi, the pump is called upon engine crank, or key on for 2 seconds. Once it doesn't see cranking rpm's, it cuts the pump power circuit. So if the key is left on, the pump shouldn't run, ECM already timed oput. The way Ford designed these fuel pump systems is the module (FPCM) controls pump voltage, varying the pump rpm, to vary fuel pressure. Sadly the module was placed in the worst spot, getting road crap thrown on it constantly.
Another quality repair Eric!!!
You truly point out a method to the madness !!! Mr. Eric O....
He's using Kano Kroil as a rust spray. It's very expensive but it is the best, by far. I used to work for a major engine rebuilder and we used this to disassemble cores.
thank you brother down here in Nassau Bahamas and this was super helpful for my Tahoe hybrid. that's so sweet man continue to love your wife like Jesus loved us man for here to say she has it good because she's married to you. Blessings man
Congrats on 65K subs !
Thanks!
Eric, I love your videos, I watch them every time one comes out, but about this one I have owned and driven Chevy trucks for decades and since the crank down spare tire holder I have never had one froze up, never even saw the need to put lubricant one one of them and I usually put 200,000 to 250,000 miles on one and rarely do anything but change the Amsoil once a year,put one or two sets of plugs in it,a water pump and basic maintenance and that is usually it, no offence but you won't see me near New York,keep the videos coming
Eric, love the videos and the channel! I relate to your videos extremely well being a mechanic myself for over twenty years, but in lovely Florida without the rust you deal with lol. One thing though, I've noticed you never have a radio playing, is that because you turn it off for the videos, or you just don't have one playing period? Keep up the awesome work sir!
The DCMA (digital copyright millenium act) feelings pigs will probably make an appearance at his shop and threaten to take down his UA-cam channel for playing “free music.”
Throwing a CAN Bus and a controller on the fuel pump is over-engineering at its finest. Very thorough troubleshooting!
Thank you!! Your presentation was VERY CLEAR AND THOROUGH😅
I been doing alot of transmission repairs lately and I believe Ive found what seems to be the cause of the 3/4 issue. Ive came across this twice now and The reason it seems like its shifting 1-2-1 is because the brake light switch wires are either wrapped around the steering column or very close to it and with the rotation or vibrations its causing the wire or wires to get mangled. They are either shorting out causing alot of electrical issues with lighting, door locks, lockup,etc or they are getting broken and losing all contact. Theres sharp points catching the wires. I was traveling down the interstate one day with my 2nd transmission and out of the blue just lost all gears, i was hot because I just finished with the swap. Next transmission, no movement from the start. returned it. Now at this point it was getting to the point where i didnt know what else to do. I was trying to lock my doors with the lock button and nothing was happening. I grabbed the brake pedal and just starting pressing it and tada locks working, flashers flashing, passenger side headlight came on. I found the issue looking at why did my pedal make everything start working again.i will post pictures of the wire and location. No more issues since this discovery on 2 different occasions. Hope this may help someone.
It's a total pleasure to watch your diagnosis videos. Changing parts is cool too but diagnosis that's what pros do. GREAT Work. And always entertaining! 🎩 off to you Sir O. Ha ha
Leave it to GM what a bad design flaw where the engineer sleeping on the job lol Why would you put a FPD Module exposed to the elements so easily where salt and water can get to it and then on top of that charge a arm and leg to replace it and have to reprogram it wow. If anyone following Ivan channel he just did same thing on 2013 GMC Acadia recently also but he used silicone around computer and connection to help seal the module from getting wrecked again. Keep up the good work your videos are always enjoy to watch Eric..O
They all do it not just GM.
What a great video Eric! I just picked up a 2008 silverado from a repo auction today, I replaced 6 or 7 different fuses that someone had removed for whatever reason. Anyway, your video help tremendously! This is the same thing that is wrong with the truck I purchased.
I took some video and will post it with a credit for you! Thanks again, great video!
Great video Eric! I learn something new every time I watch your channel.
I probably would have dropped the tank and put a fuel pump in and still have the same issue.
I’m electrician and a repeat customer told me that they were going to call me to work on a well pump, time went on and they had someone else replaced pump still didn’t work. Long story short found a loose neutral wire in the switch j box
They didn’t need a pump, gotta pay to learn. She says don’t tell my husband, he didn’t ask so I was mum.
I had an awwwww moment eric.when Mrs O said she had it good cuz she married you.keep up the good work with the informative videos with much needed humor cuz some of those jobs are frustrating but you stay calm and cool or is that just good editing lol.
Too bad GM doesn't encase those electronics in resin. I guess the extra $1.50 would break them.
BMW does it and then when they fail they burn to the ground with all the potted resin as a petroleum fire. The answer is that people don't get what they pay for with domestics because if big three legacy costs and investor demands. They all dissect the reliable makers and then see how cheaply they can copy the newest tech or features everyone now wants. Ask any GM engineer how many Lexus parts he has examined before sitting down to design for the company.
Funny I was just thinking same think. Encase in something to prevent from happening again.
Overheating can become an issue when you encapsulate a circuit board in coatings. Whether or not this board would have that problem, I don’t know. If the engineers were worth a damn, they would do something different though. Finding someone to repair a bad module in a timely manner is next to impossible these days, so the module housing should have just been completely sealed and deemed non-serviceable. Ultrasonically weld the case halves together, bed the connector pins in epoxy, and never worry about it again until the capacitors go bad. Of course, mounting the module in a location that isn’t absolutely asinine, would help too...
gm filed for bankruptcy when the financial colasped hit. gm took bail out money
Resin overheats components. Those electronics are supposed to be in an interior cabin behind panels, seats, or rear seat panels. But No!!!! Auto engineers deliberately play dumb, and poorly design things, in an effort to force you to take your vehicle to the stealership. The stealer then gives a cut of their profits to auto engineers.
White grease is your friend. It will help prevent corrosion on electrical connections. That fuel pump module was seriously soaked. No wonder it failed. You'd be right at home in the UK because we have the same corrosion issues over here due to salt being put on the roads during the cold winter months.
There actually is a white lithium grease which should NOT be used on electrical connections. Silicone dielectric grease is translucent and is the proper stuff to plug into electrical connections, but these are good. The leak is on the top of the mounted box along the plastic case to metal backing plate on top.
man this guy. blows my mind!!! i need to go back to school.
School can't teach you this shit.
I’m dealing with this now, need someone to program it! What a pain in the ass !
good video bud wait till Jan 1st 2018 all manufactuers will have to make their factory scan tool compatible with j2534 tools that was the best investment I made was a cardaq m
Eric, just put your clamp over all the wires at once with the exception of the main power supplying wire, if there is any current in any of the wires it will show. You can then isolate which one. If not, then you have confirmed that the module is the source of the excessive current draw.
That clamp has only like a 3/8 inch hole, it can't take all the wires at once.
@@John_Ridley The clamp of the current meter.
The problem with circuit breakers too, is if you continue to trip the breaker, each time it trips at a lower current. So it trips at ~10A then ~9A or less, then ~8 A or less.
S10 ECM protects engine from starting and blows fuses. 3 wires to OIL sender unit were strain relieved to base of sender. Plastic cable tie caused 3 wires to chafe thru insulation and short to each other/engine block. Cut the cable tie to free the wires, inspect wires, insulate them and start your engine!!!!
She let the Shmoke out... Thanks AVE... and Eric O.
Do you have the ability to flash a new body control module in a 2005 chevy 1500?
Yes sir
I live in Georgia and i knew these people around here was full of it. I was told only a Chevy dealer had the program to flash it..Thanx.
Anyone with a j2534 interface device can do it easy
@@SouthMainAuto wonder how much that J2534 interface and software and the scanner ran you...
38:00 Eric O was channeling his inner AvE. Waiting for him to say it let the pixies out.
Would it be possible to check the fuel pump by checking the resistance of the fuel pump first rather than blowing fuses?
Either that or directly wire the pump.. preferably with a fused wire
That’s a terrible spot near the spare for that driver module. I had to replace a FP control module today in a 2015 Transit 250.
I believe Thexton makes an awesome Chevy spare tire removal kit for those trucks. Works well and made in the USA
This is the correct way to find the problem, still a little confused why the scanner did not show communication once the FPDM was disconnected. I would have thought it would.
Great diagnostic --- lousy GM design
Your Amazon link is dead!
Thank you for what you do to help the poor people...
These car companies have lost their minds with all the modules they put in cars these days. Windows, door locks, air bags, brakes, mirrors, HVAC, engine, transmission, lighting, fuel pumps, etc... all have their own modules! And they're just overcomplicated and failing all over the place. They make the cars harder to diagnose and more expensive to fix since the modules are marked way up!
Some Euro cars have OVEr 60 computers to make the car function
It is all sweeping us toward self-driving cars, why is no major country in the world making a stand against this.
That's the plan they want us all out of the repair work so they can get all the work.
Prediction cars will have a mandatory life span 10 years then the crusher.
That's the price we pay for fancy everywhere, all these neat electronics, the perfect balance between power/torque/fuel economy, and then throw in a little tightly intertwined ecosystem and planned obsolescence in for good measure. Oh yeah and you cant work on the car anymore
I give you credit on this video cuss you take your time resolving the problems same as me . 👍🏾🙂
We appreciate. Mrs Os opinion.
You forgot to turn your sniffer on ! the camera should have a little button on the back. 😉😁👍 Lol. Thanks for sharing !
In one of the electrical classes I took, the instructor repeated the old saying, "You can't put the smoke back in it, boy"
I miss the good old days of fuses and relays
Always entertained and educated by these SMA videos! Ironically, the vid listing on the right side of my screen shows a video called "Is Salt Actually Bad for You?". Um, if you own a car up here in NY and it has GM electronics in it, you bet your A$$ it is! ;)
Yes fuses and circuit breakers as not the same.
She's wet on the inside ! haaaaa. Chrome can be used BTW sir. Wet in the box , her face was priceless
i went thru this with my 09 4.8 silverado. Same codes, luckily I was in my driveway lol found that the power was not going thru the pump module. made some splice wire out of an old PS2 console, power source wire. and took the hgarness out of the module, and with a wiring diagram, found the battery power-to- fuel pump contacts and spliced them in the harness, and the pump kicked on in the tank so i knew it worked at that point lol. so i took a hammer and beat that old module out, ontop of the spare tire, and replaced it had it programmed and it works great. i siliconed the entire metal seam, and fastener holes to prevent this issue again lol and i took the old module apart and it was an orange slurry corroded inside lol
mine was so bad, it had an orange smelly burnt slurry inside, it was flooded, like i backed into lake erie and let it sit for a day lmao
I believe there was a TSB on these Fuel Pump Modules for water leaks. GM a really dropped the ball when they designed these freaking things. At least we here in the south don't have to cut the spare tires out. And if Mrs O says it's Junk, it's junk.
Old video but good stuff man learned a few things with the amperage tool. Good job!
Good to know. I just replaced my fuel pump in my ‘09 Chevy. 100k miles.
Typical shoddy GM engineering. All of these modules should be on the interior of the car or in a sealed box if outside. But, then GM and the aftermarket wouldn't be able to sell as many replacements if they engineered it correctly. JUNK!!
over engineered . just use a relay style
Pessimistic Pizza Volvo's the same . ScannerDanner has a video about Volvo's screw the people and the aftermarket Tech's
Not just GM they all do it.
Where is it looked all over Paul site cant find it?
Its probably only on his premium channel.
I'm sure you've seen it, or someone has commented already, but Ivan had a similar issue with a FPCM in a GMC Acadia.
I had a bad fule pump in my 03 avalanche which blew fuse. I put a 25 amp in place of 20 amp and got about 20k more miles out of it before it died. You can put a 25 amp in place to see if you have a dead short or a almost dead pump. Save you a tow. Also to find out if you have a bad Module. Time saving TIP
Fantastic video Eric!!!!...those modules are in the way of many things!!!!...hahahaha.....the spare tire, the road mud, rocks, just imagine you run over a log or a bush or some like that, good bye FPCM !!!!! hahahaha.....awesome vid, thank you Eric for give us this knowledge!!!!..... Greetings to all at SMA!!!!!...... :) :) :) :) :)
Great diagnostic video. Thanks for going through the thought process.
Another excellent video. By the way, next time you come across that spare tire problem, can you do a video solution? It seems goofy, that many Chev drivers have the misguided impression that they carry an accessible spare tire.
