Programming and Setup Procedures

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. The PCM Reprogramming--Refer to Service Programming System (SPS) .
  2. The Idle Learn Procedure--Refer to Idle Learn in Engine Controls.
  3. Theft Deterrent--Refer to Programming Theft Deterrent System Components in Theft Deterrent. The ECM 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. An ECM 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

  1. If the PCM needs to be reprogrammed the Idle Learn Procedure must also be performed. Refer to Service Programming System (SPS) and Idle Learn in Engine Controls.
  2. 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.
  3. 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.
