Powertrain Control Module Programming and Setup
POWERTRAIN CONTROL MODULE PROGRAMMING AND SETUP
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 Sensor (CKP) System Diagnosis in Computers and Control Systems.
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.
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.
- Turn the ignition OFF for 30 seconds.
IMPORTANT: After programming, perform the following to avoid future misdiagnosis:
- 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 Sensor (CKP) System Diagnosis in Computers and Control Systems.
- Engine replacement
- Any engine repair that disturbs the CKP sensor or it's relationship with the crankshaft reluctor wheel
- CKP sensor
