Engine Control Module: Service and Repair
Powertrain Control Module (PCM)
3.5L Gasoline Turbocharged Direct Injection (GTDI) Powertrain Control Module (PCM)
3.7L, 5.0L (4V) and 6.2L (2V) Powertrain Control Module (PCM)
Removal
All engines
1. NOTE: Any Powertrain Control Module (PCM) replacement will require that ALL customer keys are available to be reprogrammed at the time of installation. PCM replacement DOES NOT require new keys.
Retrieve the module configuration. Carry out the module configuration retrieval steps of the Programmable Module Installation (PMI) procedure. For additional information, refer to Module Configuration Programmable Module Installation (PMI).

8. 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, refer to Module Configuration Programmable Module Installation (PMI).
9. Reprogram the Passive Anti-Theft System (PATS). Carry out the Key Programming Using Two Programmed Keys procedure. For additional information, refer to Anti-Theft - Passive Anti-Theft System (PATS) Using Two Programmed Keys.
10. Using the scan tool, perform the Misfire Monitor Neutral Profile Correction procedure, following the on-screen instructions.
11. Carry out he transmission solenoid body strategy identification. For additional Information, refer to Automatic Transaxle/Transmission - 6R80 Solenoid Body Strategy.
