How to service the Engine Control Module (ECM) on GMC Savana 1500?

Engine Control Module service requires ecm replacement and eeprom programming as one solution. The correct replacement ecm needs to be verified before removing the malfunctions ecm and placing the new service ecm into position. Turn off the ignition completely before working with connectors and dis/connecting power to avoid equipment breakdown inside the units. The metal case of control modules should stay away from battery voltage and you should not handle the pin connectors or solder joints to avoid electrostatic discharge damage. Check the control module connector area for debris before looking for proper gasket installation to block contaminant entry. Any update software process on the new control module should include recording engine oil life metrics because this omission sets default engine oil requirements to 100 percent which requires an oil change at 5000 km (3,000 mi) after the previous change. The percentage of engine oil remaining life must be retrieved using a scan tool followed by recording it. First disconnect the negative Battery Cable while you disconnect all engine wiring harness electrical connectors from the ecm. Pull away the tabs which secure the ecm bracket before taking out the ecm from its positioning. Position the ecm into its bracket before securing it by letting the bracket tabs reach inside the unit then secure the engine wiring harness connectors. After reconnecting the negative Battery Cable, program any new ecms according to the necessary procedures. A scan tool can be used for determining and setting the engine oil lifetime.
