Gmt 800 Tire Pressure Light?

[uchi]

just wondering if theres a way to tell if i have the wheel sensors in my truck. the other day the sun hit the dash just right and i could see the outline of what looked like a low tire pressure light. kind of like this (!) but theres an under score under the !. my guess is that its the low tire light. but ive never seen it come on during start up like the other lights tend to do, so is there a way to test if my truck is equiped with this feature without deflating the tire?

You don't have them,No GMT800 pickup did,Some later GMT800 SUV's ('04-'06) do have them,thats why the icon is in the I/P cluster.

makes sense. its nice seeing that gm is saving a little bit of money on the sticker price by sharing parts

Be glad you don't have it. I wish I didn't. Big pain in the neck.

They've done this for years now- both my 98 Jimmy and my 03 Silvy had the text on the cluster for functions my trucks did not have. And I'm not totally sure they passed the savings onto us to be honest.

im sure we still pay full pop i was trying to brighten up my day a little. lol.

 

im actually kinda glad i dont have it, everything ive read about it shows tit to be a damn nightmare and no one seems to like it on any vehicle they have, especially when it fails and you get into big bucks for replacing parts.

I've never kept anything long enough with the system for it to be out of warranty but with my Tacoma I took it in for new tires and without telling me anything they crushed a sensor and replaced it. Except they didn't "learn" the sensor to the truck so as soon as the truck started the light started flashing (error state). I pointed this out and they played stupid and said take it to the dealer (right up the road thankfully). They told me all this, because their scan tool could tell it was a non-factory sensor in the wheel so I had them replace it, to the tune of like $320. I then called back the tire shop and ripped them a new one for this and because at this point I realized my alignment was off. In the end I got reimbursed for the cost of the sensor, but it wasn't a pleasant time (especially for them, I made more than one customer turn and leave the building before they'd even talk to me the following morning). It also took 3 or 4 tires to set the damn tow on the Tacoma. This is absurd- rack and pinion tie rods are extremely easy to set toe with and I've used the alignment machine they have in their shop- basically, if you can read, you cannot mess the alignment up. It's that simple. Bad times, but none of that is the fault of the system really. Of all the manufacturers I like GM because you can get an actual pressure reading off the sensors- both the Taco and my current Subaru just throw a light up when pressure is too low, nothing more.

Only certain models do this, you need the proper dic buttons to get these readings.

FWIW, TPMS isn't a manufacturer's option. It is required by the government that every vehicle (light duty) manufactured after September 1, 2007 have a TPMS system.

 

I don't mind the indirect type system (uses existing ABS wheel speed sensors to detect a low tire) but I despise the direct type system (sensor in each tire / wheel assembly). Only benefit I see from these systems is in cars that run run-flats.
