Adding Tpms To My Truck

Doogie · May 12, 2009

So I have an 06 Sierra CC Z71 that I have added a few mods to like DIC, Nav Power folding mirrors, about to add a rear view camera and I am going to be done. However I am havening trouble getting the TMPS system to work correctly.

I have placed all the sensors in the tires, and purchased a different PDM (passenger door module) that had the TPMS system programed. All items were purchased from somone here who added it to their Avalanche and needed a different set up. I was assured that the sensors and the PDM were a match. I plug everything up and the truck seems to recognize the new system, however through several learn attempts the truck keeps flagging a low tire pressure light.

I took it to the dealership and had a friend scan it. The truck calls for 35 psi and that is what I am running in all four tires. However when we hook up the tech II tool to the truck the computer says the tires are at 19 psi, a little more than half the actual pressure. We wen through the menu and found a place to adjust the tire pressure on the tech II tool but nothing that low was available.

That brings me to my main problem. I do not have a screen on the DIC that shows the tire pressures. It just flags the light and says check tire pressure. I asked my friend to call the tech line and ask for a new VIC number for the TPMS but they said it was unavailable for my truck. This is the same guy who got a VIC number for the DIC set up.

So my truck and the Tahoe's etc all have this capability and its available on the same year model as my truck so why not? They share the same systems and parts. I am not sure how to correct this problem other than to remove the TPMS PDM and replace it with the original PDM and abandon the mod.

I have been successful in all other attempted mods so this one puzzles me a bit. I haven't found any helpful info here. Has anyone successfully attempted this mod?

Any tips or suggestions would be greatly appreciated.

Thanks

I kinda have the same problem...I just got purchased a new set of 20 factory rims. He said he put the TPMS sensors on the tire. When I took off the factory 17's with the factory TPMS sensors paired up to my truck...after driving 5 miles on the DIC it said "Service Tire Monitor"....So I looked up in the Owners manual how the pair the TPMS with the computer system.

Step one...turn the key to the on position then turn the parking lights on and off 4 times till the horn beeps twice.

Step Two - Start with the front tire and fill or reduce air pressure for 10 sec...then wait 15 sec...the horn will sound and that tire is paired with the computer system...then move onto the pass. side front tire...and follow the same directions...

I got to step one...the horn beeps twice...then i had my friend fill up the tire for 10 secs...then we waited for 15 sec...but the horn never beeped again...so we turned off the truck then started the process over again from the step one...

I have no clue what do to here...helpppp...

It is better if you do it the other way:

Overinflate your tires to 40 PSI and then deflate them for those 10-15 secs until the horn sounds. The truck will rarely realize that the tire pressure is changing at a dramatic rate when airing up the tire, whereas the truck almost always registers a loss of air at a high rate (and it is easier to do). try this and see if the paring sequence can be completed.

try the deflation and let us know what happens.

I tried only deflation one time..but the tire pressure was at 33psi....not 40...I will try that...

I believe that your body control module needs to be reflashed to include all of the DIC functions and then try to recalibrate it. GM does not let go of those VIC numbers very easily. The problem is those VIC numbers are derived off the VIN number and if an incorrect VIN number is used, then the programming tables are all screwed up with the incorrect options. Check to see if the full DIC is unlocked on the BCM and then restart the steps to diagnosing the concern.

To answer your question, I never have attempted this modification but I used to work for GM Corp and that is how we would address a dealership's request for the VIC codes...

I did the DIC upgrade and it has the curb mirror feature and some other features like exterior light options that don't seem to do anything. How do I see if the full DIC is unlocked on the BCM? Is that something I need a Tech II tool for?

ckillls · May 27, 2009

from what ive heard those lights stay on in most peoples cars its hard to keep all 4 tire pres the same

Doogie · June 16, 2009

Any other thoughs on this mod? I am about to pull the PDM back out and quit this mod

Doogie · August 17, 2009

Getting ready to kill this mod guys, Please anyone have thoughts or ideas on this? I cannot get the DIC to show the tire pressures for the truck, I may have the wrong sensors in the wheels but I don't want the system if all it will do is show a light if something is off. I want tire pressure read out on the DIC. ANYONE!?!?!?

I'd suggest finding a few different service departments to help you, you won't be hurting your friend's feelings by going somewhere else, but your current dealership just isn't cutting it.

Stick with it, it'll work, just takes the right person to say "ah-ha!".

Keep us informed, I'd be interested in your final thought after you get it working.

I took the truck to a different service department with GMC for the DIC upgrade and they simply would not follow the directions posted here on this site. I took it to a Chevy dealership where my friend works and he was the one that tried it. I get some pretty ****ed up looks when I asked other dealers to add stuff to my truck, 'We cant to that' is all I get from them.
