Powertrain Control Module (PCM): Installation

To install, reverse the removal procedure.
NOTE: This step is only necessary when installing a new component.

NOTE: To program the ESN to the PCM, use the service scan tool PCM > Engine Number Configuration. The app will prompt for entry of the ESN. If the engine has never been replaced, the ESN can be found in PTS > HVBOM > Features.

NOTE: If the Programmable Module Installation (PMI) procedure was not successful in downloading the data from the vehicles original PCM, then the oil life data of the vehicle is lost. If this occurs, and the oil life cannot be determined through service history or customer interview, it is recommended the vehicle engine oil and filter be changed and the oil change minder reset. Restore the module configuration. Carry out the module configuration restore steps of the Programmable Module Installation (PMI) procedure. For additional information,

NOTE: If the Body Control Module (BCM) or the PCM (or both) is being replaced, the parameters must be reset in both modules or the vehicle will experience a Passive Anti-Theft System (PATS) no start. This will occur even if the vehicle is not equipped with PATS.

NOTE: Update the IQA codes after the PMI is complete.

Upload the module information from the diagnostic tool using the Programmable Modules Installation routine. Refer to: Module Programming - Vehicles With: Electronic Manual Temperature Control (EMTC) .
NOTE: This step is only necessary when installing a new component.

Carry out the Parameter Reset procedure. Refer to: Anti-Theft Key Programming - Scan Tool .
