Warning: Replacement or reprogramming of the ECM, or replacement of the clutch pedal position sensor (CPPS) or clutch pedal requires that a CPPS learn procedure be performed. Failure to perform the CPPS learn procedure may result in personal injury or damage to the vehicle or its components if the vehicle is in gear and the starter motor is accidentally engaged.
Notice:
• 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.
Important: It is necessary to record the remaining engine oil life. If the replacement module is not programmed 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.
Removal Procedure
- Using a scan tool, retrieve the percentage of remaining engine oil. Record the remaining engine oil life.
- Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection.
- Slide the lever lock to the up position in order to release the connector.
- Disconnect the body harness electrical connector from the engine control module (ECM).
- Slide the lever locks to the up position in order to release the connectors.
- Disconnect the engine harness electrical connectors from the ECM.
- Release the retaining tab located in the battery box lower half using a small screwdriver or other suitable tool.
- Remove the ECM by lifting upward after releasing the tab.
Installation Procedure
- Slide the ECM into the ECM bracket on the front of the battery box.
- Push down on the ECM until the retaining tab snaps into place.
- Connect the engine harness electrical connectors to the ECM.
- Slide the lever locks downward to secure the connectors.
- Connect the body harness electrical connectors to the ECM.
- Slide the lever lock downward to secure the connector.
- Connect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection.
- If equipped with a manual transaxle, perform the clutch pedal position sensor learn procedure. Refer to Clutch Pedal Position Sensor Learn.
- If a NEW ECM was installed, the ECM must be programmed. Refer to Control Module References.
