Service of the powertrain control module (PCM) should consist of either replacement of the PCM or programming of the electrically erasable programmable read only memory (EEPROM). If the diagnostic procedures call for the PCM to be replaced, the replacement PCM should be checked to ensure that the correct part is being used. If the correct part is being used, remove the faulty PCM and install the new service PCM. The replacement PCM must be programmed.

Important: It is necessary to record the remaining engine oil life. If the replacement module is not programed with the remaining engine oil life, the engine oil life will default to 100%. If the replacement module is not programmed with the remaining engine oil life, the engine oil will need to be changed at 5000 km (3,000 mi) from the last engine oil change.

1. Using a scan tool, retrieve the percentage of remaining engine oil. Record the remaining engine oil life.

Notice: Refer to Ignition Switch and Powertrain Control Module Connectors Notice in the Preface section.

2. Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.

Important: The PCM cover should be flexible enough to hold out of the way while removing the PCM. Remove the PCM cover only if replacing the cover.




3. Remove the PCM cover retainers.
4. Remove the PCM cover.



5. Release the spring latch from the PCM.
6. Release the PCM mounting tabs from the PCM.
7. Remove the PCM.

Notice: Refer to Ignition Switch and Powertrain Control Module Connectors Notice in the Preface section.

Notice: Refer to Handling Electrostatic Discharge Sensitive Parts Notice in the Preface section.





Important: Remove any debris from around the PCM connector surfaces before servicing the PCM. Inspect the PCM module connector gaskets when diagnosing or replacing the PCM. Ensure that the gaskets are installed correctly. The gaskets prevent contaminant intrusion into the PCM.

8. Loosen the PCM electrical connector bolts.
9. Disconnect the PCM electrical connectors.
10. Remove the PCM from the vehicle.

Notice: Refer to Fastener Notice in the Preface section.




1. Connect the PCM electrical connectors.
2. Tighten the PCM electrical connector bolts.

Tighten
Tighten the bolts to 8 N·m (71 lb in).




3. Install the PCM.
4. Ensure that the PCM mounting tabs are engaged.
5. Secure the spring latch to the PCM.



6. Install the PCM cover and cover retainers if previously removed.
7. Connect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
8. If the PCM was replaced, the replacement PCM must be programmed. Refer to Service Programming System (SPS) in Programming.
