Every time I move my tires around I have to go to my Dealer to reprogram the tire positions. At the cost of $145.00 each time.

I would like to buy the programing tool and get the programing information.

Does anyone have any advice for me? Where to get the programmer and the instructions. I didn't mention that i have two other GM cars with the same problem.

Thanks Ron M

Ron,

All you need is a big honkin magnet. Here's the gist of my previous post that might be of help to you:

"The TPS system is designed to respond to four unique ID numbers transmitted from the Tire Pressure Sensors being monitored by the car. In stationary mode, each sensor communicates every hour with the car, starting fifteen minutes after the car becomes well, stationary. Once the car goes over 20 mph, (Drive mode) the sensors communicate every sixty seconds. All TPS communications are to the RCDLR (Remote Control Door Lock Receiver). --This is the same unit that queries the fobs for a valid ID when unlocking the vehicle or actuating the ignition system.

If any TPS monitor malfunctions, the DIC will display SERVICE TIRE MONITOR and the suspected bad sensor will display dashes instead of tire pressure for that location.

If a sensor fails or you rotate your tires, the RCDLR must re-learn where the unique ID for each sensor is located. A magnet is used to force the tire to transmit (drive mode) by placing it adjacent to the valve stem. GM has a "special" tool called a J 41760 (essentially, a big honkin magnet) for this purpose.

The tires are calibrated in the following order: LF, RF, RR, LR.

To program the TPS system, select the ACC position on the ignition switch, then press the LOCK and UNLOCK buttons at the same time on the fob. The magnet is placed next to the tires in the order above until the horn chirps, signaling the sensor has been learned. The Learn Mode will cancel if no sensors have been detected for one minute, or more than five minutes pass for the whole procedure to be completed. When the RCDLR detects the first sensor, all previous sensor entries are erased.

When the last tire sensor (LR) is learned, the horn will honk twice."

Ron,

And I got a 'big honkin magnet' from inside an old computer disk drive that was being dismantled.

That must have been one Big Honkin Drive!

CC :lol

CC -

I tried 3 "big honkin' magnets" and ...no honkin' - so to speak!

I was at Costco with the Denali for a tire rotation, and they said bring it by - they had the factory magnet (J41760). Still no luck. He had to use an electronic "tool" next to each sensor to trigger them after we put it in the "learn" mode...that finally worked on mine - and that beat $145 at the dealer!

Yeah, I had to try a different magnet too, the first one worked with two or three wheels, but it took the second magnet to work with all four. I have one that is a curved shape and fits round the valve stem a little closer. Also, it helps if your XLR has been driven recently I suspect, to make sure the battery inside the transmitter is fully charged up.

Thanks for your help
