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) (Programming and Relearning) .
2. Crankshaft position (CKP) Variation Learn-Refer to Crankshaft Position System Variation Learn (Service and Repair) .
3. Theft Deterrent-Refer to Immobilizer System Component Programming (Canada) (Programming and Relearning)Immobilizer System Component Programming (North America except Canada) (Programming and Relearning) .
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) (Programming and Relearning) .
* 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.

Important: After programming, perform the following to avoid future misdiagnosis:


* Turn the ignition OFF for 30 seconds.
* 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 System Variation Learn (Service and Repair) .

* Engine replacement
* Any engine repair that disturbs the CKP sensor or its relationship with the crankshaft reluctor wheel
* CKP sensor
