The main item you need to re-calibrate (actually
it's "program the sensors" in the service manual lingo) the sensors is a
magnet to engage sensors during the training sequence. The GM tool is J
41760, but a decent powered magnet would suffice.
Make sure vehicle has been stationary for at least 2 minutes.
1 - Ignition on
2 - Press RESET to clear all IPC messages from DIC
3 - Press and release OPTIONS, scroll til IPC is blank
4 - Press and hold DIC RESET for 3 seconds
5 - Press OPTIONS again until TIRE TRAINING message is displayed
6 - Press RESET until IPC LEARN L FRONT TIRE to begin programming
7 - Install J 41760 over left front valve stem (I would try a
hefty magnet now)
8 - The horn will sound indicating LF sensor is programmed
Notice - if after 15 seconds the horn doesn't sound, remove and reinstall
tool on stem. This may have to be done up to three times in some instances.
9 - IPC will direct you to LEARN R FRONT TIRE, R REAR TIRE, then L REAR
TIRE.
Programming Cancellation:
1. Programming mode will cancel if any of the following conditions are met:
- program mode exited through DIC
- ignition turned off
- all four sensors programmed
- TPM program mode for 2 minutes with no sensors learned
2. If cancelled with less than 4 codes stored, the receiver will only accept
the codes programmed up to that point.
There you have it, good luck.
