Powertrain Control Module Programming and Setup 3.8L

The following service procedures require either a programming or a setup event performed for a complete repair.

PCM Replacement

If the powertrain control module (PCM) is replaced, the following procedures must be performed:

  1. PCM Reprogramming--Refer to Service Programming System (SPS) .
  2. Crankshaft position (CKP) Variation Learn--Refer to Crankshaft Position System Variation Learn in Engine Controls.
  3. Theft Deterrent--Refer to Programming Theft Deterrent System Components in Theft Deterrent.

    4. The PCM will learn the incoming fuel continue password immediately upon receipt of a password message. Once a password message is received, and a password is learned, a learn procedure must be performed to change this password again. A PCM which has been previously installed in another vehicle will have learned the other vehicle's fuel continue password, and will require a learn procedure after programming to learn the current vehicle's password.

  4. Engine Oil Life Remaining--When available, use a scan tool to reset the Engine Oil Life Remaining back to the original percentage recorded before the module was replaced.
  5. Transmission Fluid Life Remaining--When available, use the scan tool to reset the Transmission Fluid Life Remaining back to the original percentage recorded before the module was replaced.

PCM Reprogramming
    • If the PCM needs to be reprogrammed, refer to Service Programming System (SPS) .
    • Engine Oil Life Remaining--When available, use a scan tool to reset the Engine Oil Life Remaining back to the original percentage recorded before the module was reprogrammed.

       Important: After programming, perform the following to avoid future misdiagnosis:

    • Turn the ignition OFF for 30 seconds.
    • Turn the ignition ON with the engine OFF.
    • Use the scan tool in order to retrieve history DTCs from all modules.
    • Clear all history DTCs.

Setup for Component Replacement

The replacement of some components will require a setup procedure for complete repair.

If any of the following components are replaced, a CKP Variation Learn Procedure must be performed. Refer to Crankshaft Position System Variation Learn in Engine Controls.

    • Engine replacement
    • Any engine repair that disturbs the CKP sensor or it's relationship with the crankshaft reluctor wheel
    • CKP sensor
