In this video we have a look at a 2011 GMC that was brought here from the dealer. The customer states the TPMS light has been on for two years and took it to the local dealer who threw $1500 in parts and time at it and it still does not work. The fix was so easy it doesn't make sense.

It's a wonderful day to work on a Chevrolet Folks 2011 it's a GMC actually uh customer tells me the TPMS light or service tire pressure monitor system light has been on for a couple years now. Uh, he wanted to fix it so he took it to the dealer uh, dealer replaced from what he tells me all four of the TPMS sensors and then says we don't know what's wrong with it. we can't fix it so the dealer gave up on it. He want to know if I would take a look at it so I'm sure I give it a try.

you know, no guarantees. Obviously if they've already tried everything they could but I thought we'd take a look at it and see why on Earth you know the TPMS system doesn't seem to work now. I've never worked on one of these before I've done, you know, a Bazilian TPMS sensors and chivies. uh as they age out and the battery side and they go bad so that's usually a pretty uh you know pretty cut and dry system and they usually program quite easy.

so I don't really know what we're going to find. We're going to grab our all tool or allel TPMS tool. Uh, we use the It 600. We're going to go through and scan the sensors and see if the truck goes into programming mode and see why it doesn't like it and then hopefully we can figure out what's really going on here.

Try to zoom in on this baby so we can all see it. Uh, it's got a Bluetooth dongle. I've got it plugged in the Uh data link connector so we're going to go through here. Let it.

uh Auto ID it should. Auto ID for us should come up as an 11 GMC Sierra pick GMC All right, let's go through and skate. Didn't have any options. says 09 9 to 13.

Oops it's communicating now. it's going to check for codes. but yeah, 09 to 13 snap-in sensors here in 15 MHz So I'll let it sit here and just recode. even though we weren't going to do that at first.

Uh, we got four Dtc's I've never used this portion of the tool, so I'm not. We're going to be a little fumbly here usually I just use this for uh, reading and and writing sensors. So all right, what do we have? Left Front Low pressure performance signal invalid, right front, left rear, and right rear. So they have the same type of code uh for every single sensor so that's that's interesting.

So let's just back out of here. and then let's just go through and scan each sensor. We'll start right with the left front. All right.

pressure is low but we don't have a a low tire pressure light on. we just have the flashing light there with check TPMS system or what have you got 65 lbs there in that tire? Oh we got pressure is all over the place. Uh let's just go to Uh Relearn and we're going to do an OBD2 relearn. Let this process go through.

so that's what it says on the dash there service tire monitor system turn engion on engine off. Let this go through and new this thing all right. What set it was successful. So let's just see.

I'll take a peek in here. lights out. Let's go through and adjust the pressure so they're all correct. Tire pressures are all the same Now let all the air out of that back.
there wasn't like 65 lbs. Uh spoke with the customer because I wanted to get the story and he told me uh that he took it to the Chevrolet dealer. He told me which one. uh he's from out of town so took it to the dealer.

it's neither here nor there and then they spent they said 8 hours on it and then just says we're done. We can't figure it out. they changed. Uh, he used his terminology the module that receives the signal from the TPMS sensor.

So I I could be wrong where I have to look I think it's the driver's door switch on these or driver's door module I could be wrong. We'll look into that. I Guess they put a module in it. Um, they tried programming it, couldn't get a to program.

they were on the phone with GM forever I guess Anyhow, they told them hey, we're $1,500 deep in this thing. If you just forget about it and walk away, we'll weigh the fee and we'll just charge you 150 bucks. You have a nice day So he opted for that because he didn't want to pay the the $1,500 and still have a broken truck. They told him they put the old module back in it and that was it.

And then he told me that he's got to slip above the visor here. Uh, let's see here. Uh, let me just read this here for you. uh Customer: States TPMS System is not Oper Operational Diagnose and advise Cause: Remote Control Door Lock Receiver in operative causing fobs and TPMS systems to be in operative at well Customer: States That's all they wrote and then um in their notes here it says Remote Control Door Lock Receiver and operative causing fobs and TPMS to be an operative as well.

Tested Fobs: They are functioning according to the tester Tested: TPMS According to the tester, all four are operational. Nothing can report to the vehicle due to the receiver being inoperative upon reinstallation of old remote. Condor Loock receiver functionality returned to key fobs I Didn't notice it's key fobs worked. It didn't work okay.

Oh, hang on the seat's moving. Hold on fellas. All right. Well let's just see what we did here.

All right, all the lights are out I Grabbed the altel because I want to look at some data and I didn't want to look at on that tiny screen. So let's open up the remote control door lock receiver I was right about being a door I didn't know if it was in a driver door module or driver door switch I'm going to get some data up on the screen and we're going to take it for a rip and see what happens. Uh, the reason I called the customer is because I wanted to see if this was an intermittent problem but he said no. The light's been on for 2 years.

It's never been like off and then back on. so we'll get some data on the screen here. Got our data, got the vehicle speed. all four tire pressures up there went through everything.

Everything else looks normal just like it says. everything's normal. So this is kind of bizarre I can't be. it can't be this easy.
This is silly that they could work on it for 8 hours and just not have it function. Busy place. so TPM M light is off. We'll just go for a little ride here and see uh See if anything changes I don't know.

Kind of bizarre if you ask me. Not real sure what to make of this folks. We're driving along, everything's working. They've all switched to drive mode.

Pressures are populating. They're starting to, you know, come up as the tire pressure increases here from heat. I'll go through and you know, adjust them again. It's supposed to get cold here.

It's pretty warm out today. it's 50 but it's supposed to drop down in the 20s so we'll go. We'll adjust them for that. like I say it's pretty pretty bizarre.

lights out on the dash up to have you guys tell me what you think down in the comments section folded over here folks have a look so we can see like I say all pressures are working good. Like I said, they've all switched from learn to drive mode TPMS indicator is off yeah I don't know what to say. it is what it is seems kind of silly and like I said all of you guys tell me what you think down in the comment section. um checked it for codes.

There's no codes in it, everything seems to function and like I say talking to the customer he States it's not an intermittent problem, it just quit and that was it. And then you know like I say he was going to be500 deep. he just they called it. It just seems really bizarre that if it was at the dealer they couldn't fix this problem.

I mean this is this one's old enough that you don't even need a TPMS tool to uh, relearn the sensors you do with the key fob and letting air out of the tires. We've made videos on that before so I chose to use a tool because it's faster, but essentially it does the same thing. So I'm not real sure why I didn't look at the IDS that were written in it. We could probably go back and and maybe see that on the footage and compare them to the IDS we put in it.

Um, I don't know what their process is at the dealer so it just seems really weird what I'm going to do I've got some other work to do on this I'm going to go back, do that work, let it sit, take it for another drive, and if something acts up, I'll come get you. otherwise we'll just give it one of these. We don't know why. Uh, kind of feel bad for the dealer if it really was that simple and there was just a part of their process that wasn't working I don't know.

Anyways, work your way in that comment section. let me know what you think, questions, comments, the ins, the Facebook you know where to find us. Just remember viewers, if I can do it, you can do it. Thanks for watching.

    Okay, so from my understanding, this was a programming issue? 'Signal invalid' codes make me think that the sensors were receiving faulty data and couldn't produce accurate outputs (please feel free to roast my amateurish understanding here 😅). Eric did a relearn for the sensors to resynchronize with the module(s) and then after that the sensor was able to receive valid information?

  2. Avataaar/Circle Created with python_avatars Michael Bolton says:

    Another Cruncholet. The dealer sat on it for eight hours, didn't change anything, wrote a BS receipt and a made a quick $150.

  3. Avataaar/Circle Created with python_avatars D.A.L. says:

    Gotta love the stealership

  4. Avataaar/Circle Created with python_avatars D.A.L. says:

    I hate those automatic seats. I don't know how many times I get in a customer vehicle and it tries to smash me into the dash. Even worse when I don't know where the seat buttons are

  5. Avataaar/Circle Created with python_avatars Who said that! says:

    My 2012 Sierra is starting to do this. Ever since I brought it to get new tires put on. And they refuse to even look at it again. Thanks kaltire not ever bringing it back to you again.

    gm dealer could not fix it? sounds like they did not like the customer,just my .02

    What area of the country are you in, looks a lot like north ga.

  8. Avataaar/Circle Created with python_avatars Jason Gomez says:

    I appreciate you for showing us your skills and how you fix hard to find shorts and diagnose major issues 💯

  9. Avataaar/Circle Created with python_avatars Jason Gomez says:

    This guy I've watched for years is always on point with trouble shooting yeah dealer lets pay south main auto to fix it for us and tell the customer yeah we fixed it 😂

  10. Avataaar/Circle Created with python_avatars Jason Gomez says:

    They have to teach techs to use there scantools and they probably didn't know how to use the tpms scantool 😂

    Inexperienced technicians that work at this dealership Eric you wish they were all that easy great video Easy money

  13. Avataaar/Circle Created with python_avatars forresta65 says:

    a fair dealership. is this a unicorn?

  14. Avataaar/Circle Created with python_avatars Jim Thompson says:

    I’ve had the TPMS tool learn the sensors on the car next to me! I’ll bet forcing the learn through OBD2 was the real fix.

  15. Avataaar/Circle Created with python_avatars Rich Murphy says:

    Looks like it was set up on you. They’re testing your integrity.

  16. Avataaar/Circle Created with python_avatars Rick Hayes says:

    I think this guy got ripped off.

  17. Avataaar/Circle Created with python_avatars DIY Dave says:

    TPMS is in the running for most needlessly overdesigned system in all the automotive industry.

  18. Avataaar/Circle Created with python_avatars Captain Buggernuts says:

    Drug dealer, casino card dealer, car dealer… I'm surprised that lawyers don't have some version of dealer in their name.

  19. Avataaar/Circle Created with python_avatars B A says:

    Guess the dealership tech needs to learn the re-learn process.

    Sticky fingers, when you worked the fob buttons like crazy it made them contact fully. Kinda like giving it the Fonz.

  22. Avataaar/Circle Created with python_avatars Mike Tanner says:

    😁lazy or incompetent
    The truth most likely is that they as you just said they don't want to do their jobs
    Trying to force people into buying a new car
    Hope you have a great day brother
    Keep up the great work
    Just saying

  23. Avataaar/Circle Created with python_avatars Mark Faulkner says:

    Eric having dealt with main dealer at VW it appears to me that the vast majority of so called technicians at main dealers are incompetent. they will occasionally have a gem but probably abused them so they leave. Independents is the way to go.

  24. Avataaar/Circle Created with python_avatars Hot Rod 1949 says:

    Happy thanksgiving Eric to you and your family and staff

  25. Avataaar/Circle Created with python_avatars George Kelly says:

    Sounds like that dealership didn't know what in the Chevy Thunder they were doing.🤣

  26. Avataaar/Circle Created with python_avatars Bacon Munchers says:

    Another repair where the original part ended up being ok. Also looks like the dealer didn't do a re-learn after the part swap.

  27. Avataaar/Circle Created with python_avatars Rick Edwards says:

    Having worked in dealership service departments for half of my adult life Ive seem this situation repeated all too often. The service writer documents the complaint then the dispatcher,who believes it to be such an easy repair, gives the job to the most junior person in the shop thinking it will simply require tire sensor replacement. The tire changer replaces the sensors but can't figure the programming tool out. From that point on the story spirals out of control and the hours rack up and parts cannon is emptied.
    At best the dispatcher pulls the job back and reassigns it to a qualified tech or at worst the hours are billed and the customer is stuck with the bill only to return for the comeback treatment days later. The dealership then either refunds the entire labor charge or finds a qualified tech to pull the bacon out of the fire.
    Well done Eric. Rational thought wins out over pattern failure guesswork.

  28. Avataaar/Circle Created with python_avatars HELLRAISEHR says:

    Customer States. The Chevy dealership is useless.

  29. Avataaar/Circle Created with python_avatars jedgeled says:

    i worked at ford dealerships for 38 years,,the last place i worked there was one guy who was the brake king,,,i thought he must be smart ,,till one day he asked me how to use a scanner cause the antilock light was on and he had 5 more years of experience than me,,,there are too many guys out there that really dont know how things work!!!

  30. Avataaar/Circle Created with python_avatars Ed H. says:

    That is the worst kind of problem to have. The intermittent ghost! You did all anyone could have. great job! Ed Hicks

  31. Avataaar/Circle Created with python_avatars samuel mcgill says:

    Dude,if the problem doesn't show up on a laptop,these incompetent losers are lost. Mechanics are a dying breed.

  32. Avataaar/Circle Created with python_avatars Shaun O says:

    If I had that truck and experienced what you did, I wouldn't be able to find a fault either. Then I'd give the vehicle back to the customer who'd have the dash light up within five miles from my shop. I hope you'll have better luck than that.

  33. Avataaar/Circle Created with python_avatars Wade Taylor says:


  34. Avataaar/Circle Created with python_avatars Steve Loux says:

    With all of the chaos in the world, there is some sense of refuge when we find ourselves vicariously working with Eric in the shop. 🙂

  35. Avataaar/Circle Created with python_avatars gadasa videos says:

    Whenever my tires have been swapped to non sensor tires or to another set I'm surprised at how far I can drive before the dash light comes on.

  36. Avataaar/Circle Created with python_avatars gadasa videos says:

    Feel sorry for the dealer? Feel sorry for their customers.

  37. Avataaar/Circle Created with python_avatars The Way I Do It says:

    I'm surprised there's no comments on the vintage Harley lovers decal in the window near the registration. Anyone?

  38. Avataaar/Circle Created with python_avatars LexTeakMiaLoki says:

    Nice job Eric, that was a quick 1500. 🤣🤣

  39. Avataaar/Circle Created with python_avatars you need jesus says:

    I have a '14 cruze eco. In 2015 when switching to snow rims and tires. The chevy dealer couldnt learn the tps sensors. They wanted to replace all sensors and modulators. The problem was the E-brake needed to be on to enter learn mode.😂

  40. Avataaar/Circle Created with python_avatars Steve Corey says:

    Precisely why at age 68 I still repair 98 o/o of my vehicle 🚗 in my fleet and many friends and relatives

  41. Avataaar/Circle Created with python_avatars BRIAN VELTRI says:

    Wow I thought my GM dealer sucked lol

  42. Avataaar/Circle Created with python_avatars Chinook Helomech says:

    Even tire companies whose bread and butter is selling tires have problems working with TPMS systems. I took an older car (2004 Chrysler) into my local tire company and had them replace all 4 tire TMPS sending units (with 4 new tires). It did not work after they installed them and I had to take it back in twice for them to get the system to read the sensors, and work properly. Has been fine since then – 2 years, but amazing that they could not get it right without call backs.

  43. Avataaar/Circle Created with python_avatars Joseph says:

    He’s obviously not telling the whole story and just bashing the dealer
