Removal Procedure
CAUTION:
- Turn the ignition OFF when installing or removing the control module connectors and disconnecting or reconnecting the power to the control module (battery cable, powertrain control module (PCM)/engine control module (ECM)/transaxle control module (TCM) pigtail, control module fuse, jumper cables, etc.) in order to prevent internal control module damage.
- Control module damage may result when the metal case contacts battery voltage. DO NOT contact the control module metal case with battery voltage when servicing a control module, using battery booster cables, or when charging the vehicle battery.
- In order to prevent any possible electrostatic discharge damage to the control module, do no touch the connector pins or the soldered components on the circuit board.
- Remove any debris from around the control module connector surfaces before servicing the control module. Inspect the control module connector gaskets when diagnosing or replacing the control module. Ensure that the gaskets are installed correctly. The gaskets prevent contaminant intrusion into the control module.
- The replacement control module must be programmed.
- Prepare the engine control module (ECM) for the replacement. Refer to Control Module References .
- Using a scan tool, retrieve the percentage of remaining engine oil. Record the remaining life engine oil life.
- Battery Negative Cable Disconnection and Connection - Disconnect
- Disconnect the 3 engine control module electrical connectors (2) from engine control module (1) and hang them aside.
-
Remove Engine Control Module (1) @Engine Control Module Bracket (2) - Unlock the retaining tabs.(3)
NOTE:
It is necessary to record the engine oil life percentage remaining. Use the scan tool to reset the engine oil life remaining back to the original percentage recorded.
CAUTION:
In order to prevent any possible electrostatic discharge damage to the ECM, do not touch the connector pins.
