• Q: How to replace the Engine Control Module (ECM) on 2010 Chevrolet HHR?

  A: Start Engine Control Module (ECM) replacement by using a scan tool to obtain and record engine oil life percentage. The negative Battery Cable requires removal to stop electrical problems from occurring. Start by disconnecting the ecm electrical connectors while also removing the ecm/tcm cover from its position. You must ensure that both the metal control module case and the battery voltage do not touch each other for the prevention of damage. The ecm extract from its underhood junction block bracket requires removal after you detach the plastic retainer tabs. Installation of the new ecm involves pushing it downwards until tab locks occur while connecting electrical connectors before replacing the ecm/tcm cover. Reconnect the negative terminal while completing ecm programming. Vehicle owners with manual transmission models need to conduct the clutch pedal position sensor learn procedure because this ensures proper sensor functionality. Before installing the replacement module users need to input the recorded engine oil life data to prevent default settings that require an oil change at 5,000 km (3,000 mi) from the previous service.
