How to service the Engine Control Module (ECM) on Cadillac Escalade ESV?

The Engine Control Module (ECM) service requires either ecm replacement or eeprom programming. Verify that the replacement ecm matches the unit specification before you eliminate the broken ecm for new service ecm installation. Power should be cut off from the ignition while handling control module connectors and disconnecting or reconnecting power because this prevents damage to internal components. Letting the metal case of the control module touch battery voltage during servicing will result in damage to the system. Users must avoid touching the circuit board solder connections and connector pins because electrostatic discharge can occur when cleaning the control module connector surfaces and their adjacent area. Check that the connector gaskets of the control module are securely in place to defend against contaminants. The programming of the new control module should be performed while recording the current engine oil life percentage because a missing record will set the oil life to 100 percent thus requiring an oil change at 5,000 km (3,000 mi) since the last change. You should initiate removal by obtaining necessary data from the scan tool about engine oil life percentage through recording it and following up with negative Battery Cable disconnection. Disconnect upper and lower electrical connector retainers first and then remove the connectors from the ecm before removing the ecm by unclipping its retainer tabs from the bracket. During installation push the ecm into place after you put the bottom tabs from the ecm into the bracket. Reconnect the negative Battery Cable while reconnecting upper and lower electrical connectors which should have their specific retainers back in place. Programming of the ecm needs to occur if a new unit was installed.
