GM PCM relearning

General Motors does not provide a specific procedure for driveability relearn. If a vehicle battery was disconnected for facilitating repairs or a Powertrain Control Module (PCM) was replaced, driving the vehicle will enable the PCM to relearn driveability. Inform your customer that he/she may experience driveability different from what they are accustomed to until the PCM completes it's relearn function.
