Control Module Learning Ability

The control module has a learning ability which allows the control module to make corrections for minor variations in the fuel system in order to improve driveability. Whenever the battery cable is disconnected, the learning process resets.

The driver may note a change in vehicle performance. In order to allow the VCM to relearn, drive the vehicle at part throttle with moderate acceleration.
