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 CKP System Variation Learn Procedure in Engine Controls.
3. Theft Deterrent-Refer to Programming Theft Deterrent System Components in Theft Deterrent.

   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.
