PCM Replacement
WARNING: This page is about a different car, the 2005 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
If the powertrain control module (PCM) is replaced, the following procedures must be performed:
- PCM Reprogramming-Refer to Service Programming System (SPS) .
- Crankshaft Position (CKP) Variation Learn-Refer to CKP System Variation Learn Procedure in Engine Controls.
- 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.
- 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.
- 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.
