How to replace the Engine Control Module (ECM) on Chevrolet Equinox?

A safe procedure starts with turning off the ignition system when replacing or uninstalling connectors attached to the Engine Control Module (ECM) and its power connections that encompass Battery Cable and control module fuse. The control module metal case must not come into contact with battery voltage and touching either connector pins or soldered components leads to electrostatic discharge damage. Prior to servicing the control module one should conduct debris removal from connector surfaces and double-check the gaskets for correct installation to stop contaminant intrusion. A scan tool should be used to record the life span of engine oil and automatic transmission fluid. Failure to program these values into the new control module will force the system to initialize default values at 5000 km (3,000 mi) and 83000 km (50,000 mi) respectively. Disengaging the ecm retainer from the battery shield occurs by sliding it toward the back before removing both components from the shield. Break the negative battery connection as well as remove the two engine wiring harness electrical connectors from the ecm. Install the ecm by connecting its two engine wiring harness electrical connectors followed by putting it back on the battery shield before secure the retainer into place. First place the ecm and retainer on the top of the battery shield after which push the retainer toward the rear to create a proper connection and reconnect the negative Battery Cable. Reprogramming of the pcm follows installation completion.
