Service TPMS SYSTEM warning in DIC

[MaverickZ71]

Is there a fuse to pull or any other way to disable TPMS to get the constant warning error and yellow TPMS light to shut off? 

 

Firestone refuses to use GM sensors, and theirs ($75+ each for part and dismount/mount) don't even last 2 years before the batteries go bad. I currently have a rear passenger tire stuck at zero and a front passenger tire bouncing between 37 and zero, when they both actually have 35psi cold.

I don't know of any fuse, or any other way to disable that system. Engineers have got very clever at integrating ALL systems together, so that if one "disappears", it throws codes or causes other problems down the line (Via CAN, or other communication protocols).

 

My recommendation is to buy Autel sensors, and program them with an Autel scan tool. They're cheap, and if I can program them without issue, ANYONE can (This stuff INFURIATES me ... which is why I quit the industry). One sensor will work with 2 different frequencies, so it can be used in many different brands. For example, one's for a '08 Tundra worked in my '07 Silverado.

 

If you don't want to cough up the cash for a scan tool (Understandable if you're not earning a living with it), just go to any garage or body shop with a scan tool. You'll be better served to have them install the sensors for you, too. Easy to do with a tire machine - just let the air out, use the bead breaker to hold the bead in while you swap sensors. Done! Nice and easy for them and shouldn't cost much.

 

And steer clear of chain tire stores. They are AWFUL. They are the reason I bought my own tire machine and balancer LONG before I started my own shop.

 

EDIT - the cheapest way would be electrical tape over the light.

This is what i do: Buy the GM sensors, go to your local mom and pop trusted tire shop/ repair center. Ask them to install them for you and have them learned to the truck (or buy the $20 tool and learn them to the truck yourself). Now you're good to go for 8-10 years.

 

As far as disabling it, no, theres no feasible way. I've searched high and low, and previous to the 2008 model year mandate, one would still have to program a new BCM with a VIN that didn't have TPMS system. Modern GM vehicles, forget it.

GM = $49

Autel = almost half that @ $25 (for the rubber one - the metal one is a little more)

Just FYI, you don't need an Autel scan tool to program these MX sensors. They're universal. Any higher-end scan tool or TPMS tool will work. GM uses 315 MHz for the sensors.

 

Like I always mention, I would steer clear of Amazon and eBay for things like this, due to the insane amount of counterfeit parts sold on each. China is getting really good at duplicating everything, right down to the print on the box. The sensors are chinese to begin with, but counterfeit parts are complete, unreliable garbage.

So if you don't have a scan tool with TPMS programming capability (not the cheap relearn tool) then you'd have to shell out for that as well hence why I recommended a GM or equivalent sensor. Yeah, if you have a buddy or are close with your tire shop, they might do it for you. Also one should shop around for sensors. I purchased a set of new GM for my '21 for about $30 each from another GM parts site.

A cheap tool isn't going to program a GM sensor, either.

 

A $30 GM sensor is a red flag for a counterfeit part. No legit dealer or GM parts supplier is selling them that cheap.

Good grief, I literally said a cheap relearn tool wouldn't work and you'd have to have a scan tool or dedicated TPMS scan tool (that are usually a few hundred dollars minimum). I suggested OP purchase a GM/ AC Delco sensor for reliability, and gave a simple example of a price point. We don't even know what exactly OP drives and the p/n's (and consequently the prices) vary wildly for the model years, even if most of them are interchangeable.

 

Also, the price went up a small bit on mine, and these are just an example

But still, add the 5% discount and you're at $40 each.

 

Seriously, I'm trying to help OP and you're arguing with me. WTF

[Jsdirt]

Not arguing - was stating facts based on what was true when I was doing this full time.

 

Things change all the time in this industry - I wasn't aware of "pre-programmed" sensors being available. Shocked, actually. Seems GM's mission has been to make things more and more difficult for owners to handle on their own for the past 20+ years.

[carkhz316]

Thats basically why I recommended the GM ones since they're pre-programmed and make it much easier for the end user to add them to their vehicle since they just have to be physically installed, then learned with a cheapo tool. This is opposed to a shop stocking programmable ones that cost more so that they can be used in a variety of vehicles.

 

But yeah, I agree with the difficulty and complications implemented by GM to just be annoying or be a cash grab, such as how one could learn the keyless remotes and tpms without tools on 2010 and older model years, then they tweaked the software to force a scan tool sequence......just because. Oh, and requiring two working keys/ smart fobs for 2018+ vehicles to self-learn a new key/ fob as opposed to requiring only one. Dumb.

[Jsdirt]

Yeah, absolutely ridiculous the crap found on newer stuff. Looks like GM finally copied FoMoCo ... or FoMoCo paid them off so everyone would be "equally shitty" - that seems to be the way things are these days.  Ford required 2 keys right from the start of these systems. I wouldn't drive a new one if I were paid to, unless I got to trade it in every 3 months. Got enough headaches in my life!

 

 

Ok, so I misunderstood the "pre-programming" part - I thought they'd be GTG right out of the box. I took that to mean they sell them as LF, RF, LR, RR.  My bad.

 

So it's just the sensor ID that's programmed. In that case might as well buy the Autel one, since you can program / learn them with any mid-level scan tool. 

 

I remember when I first got my '07 Silverado, and attempted the owner's manual procedure through the DIC for relearning sensor positions after a tire rotation. What a cluster$#ck that turned into! Round and around I went - 10x - with the same result. Go through all the lights and horn toots, only to be left letting ALL the air out of the last tire trying to get it to detect SOMETHING, only to be left hanging endlessly! I was f'ing LIVID!!! Guarantee GM did that one on purpose to get you back into a dealership so they could try and sell you something.

 

After the guys took literally 3 minutes with the fancy $500 wand under warranty back then, they were GTG every time afterward - didn't have a single glitch for the next 16 years.

I bought a complete set of OEM sensors from TPMS.com years ago and had no issues. They sell the OEM supplied units at prices much less than retail or tire shops. I had the tire shop install them when I bought new tires so there was no additional charge.
