Learn Mode Cancellation
WARNING: This page is about a different car, the 2010 Cadillac STS. However, it is still accessible from the selected car via links, so may be relevant.
The learn mode will cancel if the ignition is cycled to OFF or if more than 2 minutes has elapsed for any sensor that has not been learned. If the learn mode is cancelled, the original sensor IDs will be maintained. If the learn mode is cancelled after any sensor is learned, the DIC will display dashes instead of tire pressures for the remaining unlearned sensors and the learn procedure will need to be repeated for the system to function properly.
