FAQ for Engine Control Module Repair
Q: How to remove the Engine Control Module?
A:
First, you need to use a scan tool to retrieve the percentage of remaining engine oil. Then, please disconnect the negative battery cable, disconnect the engine wiring harness electrical connectors from the ECM, disengage the retainers securing the ECM to the bracket, and remove the ECM from the bracket. Finally, you should remove the ECM bracket bolts and nuts, and remove the ECM bracket from the studs on the intake manifold.
