PCM Reprogramming

WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

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 diagnostic tool.

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