Good day to all--
I have the Orange tire pressure sensors in my 2002 coupe that were working fine until I installed a new AGM battery and now the won't re-program. I'm using dual magnets that came out of a microwave that worked when I first had them installed with my new aftermarket wheels from OE Wheels. I even had the dealer try and program them when I was having some other work done and while they now show a number on the DIC they are stuck on 50, 42, 30, and 21 which keeps telling me I have a low RF tire(which I don't). I bought 4 new GM sensors to install but hate the thought of breaking down the beads of the low profile tires and possibly causing damage so I thought I'd reach out to you guys first for a possible solution.
One other thing I'll mention is I was having the C1214 code which meant a possible ECBM problem but it's been 5 weeks and no more codes since installing the new battery.
Thanks for any input.

 

I pull my battery out for 5 months and when I put it back in, the TPMS work just fine.

 

YEP,,, I agree!

Do your FOBs function properly?

 

Similar thing happened to me. My car, a 2002 coupe, is equipped with 4 Orange Electronics tire pressure sensors. While changing the AC compressor I had the battery out of the car for 3 days. Now only one of the four sensors reports tire pressure. I have made several attempts to program the sensors with no luck. The same single sensor continues to report pressure but the other three remain blank. Fobs work fine and there are no codes. I bought the sensors online about a year ago and they programed fine when I installed them. If I read the sensor date codes correctly they were manufactured in 2008. I have seen reports online of poor battery life with the Orange Electronic sensors. I suppose low sensor battery voltage could be the problem. I intend to replace mine with Schrader sensors when I get new tires.

 

I just got back from Nat Tire & Battery and a fellow who used to work at a Chevy dealership checked out my car and he couldn't get the sensors to work using all of his tools and he also checked out the system and said the sensors are transmitting but he is just as baffled as I am. There are no codes at all showing on the DIC so that is no help. One thing he mentioned was to replace the door module that controls all of these features and re-program the fob. After a trip to the dealer and a quote of over 400.00 for the module they still couldn't tell me which door module to replace. Does the driver or pass side control the sensors? This is really weird that no one can give me a definitive answer and I'm not crazy about throwing hundreds of dollars at something that may or may not fix this problem. I had new sensors ready to install but John(NTB) said the ones I have are transmitting but the receiver is more than likely the culprit. Anybody ever replace their door module?

 

I think that if you had a problem with the door control module you would have a LDCM or RDCM codes. Did you drive the car to see if the TPM wake up then try programming them and go for another drive and see if the are working.

 

There is no door module. There is a module inside the trunk/hatch area above and behind the driver's side tire near the top surface. It is a receiver. It gets signals from the key fob and the TMPS sensors.

Chances are if the key fob is still working, the receiver is still working too and not your problem with the TPMS sensors.

My guess is something with the sensors. As stated above, pull all the codes and post them here so people can help to debug it.

 

The OP stated there were no codes in the DIC.

 

The DOOR MODULES are NOT part of the TPMS system

The TPMS consist of the RFA module (or Remote Control Door Lock Receiver) and the BCM.. It connects to the BCM thru the serial data buss:



It looks like this and is hidden on the drivers side above the wheel well behind the plastic that encloses the speaker:

 

Are you sure you did the proper procedure to check the codes, I did re read you original post and you replaced the battery, you should have at least no communication codes.
The drivers door control module is part of a serial buss, but if there was a problem you would have the no communication codes. Below are some of the common codes when the battery has been disconnected. You may not have all of them.....

I double checked for any codes and there are none. I went for a 15 min ride, got out and proceeded to try and reprogram the sensors again and got nowhere. Once I got home I disconnected the battery
for a few minutes and that cleared out all the info on the sensors(each one is now blank-no xxx's) and at least I don't have the low front tire message anymore. I've decided to just leave it as is and keep an eye on my tire pressure the old fashion way just like my other three cars.
Thanks for the replies but this one is a real mystery.

 

I'm running on new Bridgestone tires and I plan on just checking the air pressure w/a digital tire gauge. I should be fine barring an outright blowout and even then the TPS wouldn't be of much help. I'll post any new findings in the future. Appreciate the help guys.

 

Bill,
Is that your car in the pic? I am wondering because I see the car in the pic has interior insulation, and I have noticed my TPMS in the front seem to be acting up since I put my insulation in last spring. I'm wondering if the sensors are dying or if there is some sort of interference due to the metallic coating on the insulation.

 

Thanks for this info Bill--Is there only the one fuse in the TPMS and where might that be? It's a long shot but stranger things have happened in working w/my Vette so I figured it's worth a try. Thanks!

 

I'm pretty handy but reading schematics isn't my strong suit. I'm just grasping at straws here cause no one anywhere can offer up a solution to this issue. Thanks for the assist.
