Removal Procedure
- Using a scan tool, retrieve the percentage of remaining engine oil. Record the remaining engine oil life.
- To prevent internal PCM damage, the ignition must be OFF when disconnecting or reconnecting power to the PCM. For example, when working with a battery cable, PCM pigtail, PCM fuse, or jumper cables.
- Remove any debris from 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.
- Disengage the connector position assurance (CPA) retainers.
- Disconnect the engine wiring harness PCM connectors from the PCM.
- Disengage the CPA retainer.
- Disconnect the body wiring harness PCM connector from the PCM.
- Disengage the PCM bracket mounting tabs, while removing the PCM (1).
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 percent. If the replacement module is not programmed with the remaining engine oil life, the engine oil will need to be changed at 5 000 km (3,000 mi) from the last engine oil change.
NOTE:
In order to prevent internal damage to the PCM, the ignition must be OFF when disconnecting or reconnecting the PCM connector.
IMPORTANT:
NOTE:
Do not touch the connector pins or soldered components on the circuit board in order to prevent possible electrostatic discharge (ESD) damage to the PCM.
