Powertrain Control Module Programming and Setup 3100 (LG8)

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

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

1. PCM Reprogramming--Refer to Service Programming System (SPS) .
2. 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.

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.

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.
