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

Engine Control Module (ECM) replacement must start with turning off the ignition to protect the connectors during handling and power unplugging. Touching the control module metal case to battery voltage can cause damages so avoid this practice while also prevent reaching into pins or board components to avoid static discharge. Check each control module connector surface for dirt before inspecting that the gaskets were installed correctly to stop contaminants from getting inside. The replacement module must receive essential values for engine oil life and automatic transmission fluid life since missing them will trigger the replacement of engine oil at 5000 km (3,000 mi) with a 100% default value as well as transmission fluid replacement at 83000 km (50,000 mi). Start the removal process by scanning the vehicle to extract the current percentages of engine oil and transmission fluid life which need recording. To disengage the ecm retainer from the battery shield you need to move it backward until separation occurs before removing the retainer. Reposition the ecm in place. The first step involves Battery Cable disconnection followed by placing the battery shield over the battery and finally placing the ecm on top of the shield. You must disconnect both electrical connectors from the ecm located in the engine wiring harness. The installation procedure includes attaching engine wiring harness connections to the ecm while removing the battery shield and then reattaching the negative Battery Cable. Secure the ecm retainer to its installation position on top of the battery shield by sliding it backward until it clicks into place with the shield.
