Removal Procedure
NOTE:
Turn the ignition OFF when installing or removing the PCM connectors and disconnecting or reconnecting the power to the PCM (battery cable, PCM pigtail, PCM fuse, jumper cables, etc.) in order to prevent internal PCM damage.
- Using a scan tool, retrieve the percentage of remaining engine oil and the remaining automatic transmission fluid life. Record the remaining engine oil and the remaining automatic transmission fluid life.
- Turn OFF the ignition.
- Disconnect the battery negative cable. Refer to Battery Negative Cable Disconnect/Connect Procedure in Engine Electrical.
- Disconnect the mass air flow/intake air temperature (MAF/IAT) sensor electrical connector.
- Loosen the intake air duct clamp at the throttle body.
- Loosen the air filter element/powertrain control module (PCM) housing cover screws.
- Remove the air filter element/PCM housing cover, MAF/IAT sensor, and intake air duct.
- Release the PCM electrical connector locks and disconnect the electrical connectors from the PCM.
- Remove the PCM.
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.
IMPORTANT:
It is necessary to record the remaining automatic transmission fluid life. If the replacement module is not programed with the remaining automatic transmission fluid life, the automatic transmission fluid life will default to 100%. If the replacement module is not programmed with the remaining automatic transmission fluid life, the automatic transmission fluid will need to be changed at 83000 km (50,000 mi) from the last automatic transmission fluid change.
