An updated calibration or software release is available for either the PCM or Transmission Control Module (TCM).

This procedure assumes that the scan tool is properly configured to the dealership network with either a wired or wireless connection and that the PIN has been obtained in order to program the PCM. For help on how to network the scan tool, use the "Help" tab at the top of the diagnostic application.
