Programming The Engine Serial Number For A Replacement PCM
The engine serial number on a replacement PCM is blank and requires programming. Manual data entry is required. If the old PCM is capable of communicating, the engine serial number is available using a compatible scan tool. Refer to the scan tool manufacturers manual for instructions.
Making Changes To The VID Block
A programmed PCM may require changes to be made to certain VID information to accommodate the vehicle hardware. Refer to Module Reprogramming on the scan tool.
Making Changes To The PCM Calibration
At certain times, the 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 or Module Reprogramming on the scan tool.
