NOTE: After the PCM is successfully reprogrammed, clear any TCM DTCs that may have been stored during reprogramming.

At certain times, the entire EEPROM needs to be completely reprogrammed. This is due to changes made to the strategy or calibration after production or the need to reset the VID block because it has reached its limit. Refer to PCM/Module Reprogramming on the scan tool.
