This bulletin involves selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software (calibration changes) and
replacing the motor mounts with revised parts for this condition only.

Follow the steps presented on the MDS and DRBIII(R) which will allow the DRBIII(R) to obtain the current part number of the PCM.
