Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Removal Procedure
- Using a scan tool, retrieve the percentage of remaining engine oil. Record the remaining engine oil life.
- Disconnect the negative battery cable from the battery and move aside.
- Release the ECM cover mounting holes (1,5) away from the mounting tabs on the ECM mounting bracket.
- Release the ECM cover (8) from the mounting bracket.
- Remove the ECM cover.
- Disconnect the ECM harness connectors (6).
- Release the spring latch (2) from the ECM.
- Release the ECM mounting tabs (3) from the ECM.
- Remove the ECM (4) from the engine compartment.
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.
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.
