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

Replacement of the Engine Control Module (ECM) requires either one to program electrically erasable programmable read-only memory (EEPROM) or to install a new ecm unit. Check the replacement ecm is the right component before taking out the broken ecm and putting in the newly installed service ecm. It is essential to shut off the ignition before working with control module connectors anddisconnecting or reconnecting power because this protects the internal components from harm. The metal case of control modules must be kept away from battery voltage when serving control modules and handling pins or components that require soldering will prevent electrostatic discharge damage. A thorough cleaning of the control module connector surfaces must occur first followed by checking for correct alignment of the connector gaskets to stop the entry of contaminants. The programming of the new control module requires immediate attention followed by documentation of remaining engine oil life because absence of this programming will set engine oil life to 100 percent leading to a required oil change at 5,000 km (3,000 mi) from last oil change. Initiate removal procedures by using a diagnostic tool to obtain and mark down the current engine oil life percentage before unplugging the negative battery terminal. To replace the ecm it is necessary to separate the engine harness connector retainer locks so that you can disconnect the connectors from the module. Drain the ecm out of its bracket by detaching the bracket retainer tabs from the bracket. Install the ecm by slotting its bottom into the ecm bracket tab until it secures then mate the engine wiring harness electrical connectors before engaging their retainers. Completion of the task requires reattaching the negative battery terminal while instructing the ecm programming process when installing a fresh component.

Q: How to service the Engine Control Module (ECM) on GMC Yukon?
A:
Replacement of the Engine Control Module (ECM) requires either one to program electrically erasable programmable read-only memory (EEPROM) or to install a new ecm unit. Check the replacement ecm is the right component before taking out the broken ecm and putting in the newly installed service ecm. It is essential to shut off the ignition before working with control module connectors anddisconnecting or reconnecting power because this protects the internal components from harm. The metal case of control modules must be kept away from battery voltage when serving control modules and handling pins or components that require soldering will prevent electrostatic discharge damage. A thorough cleaning of the control module connector surfaces must occur first followed by checking for correct alignment of the connector gaskets to stop the entry of contaminants. The programming of the new control module requires immediate attention followed by documentation of remaining engine oil life because absence of this programming will set engine oil life to 100 percent leading to a required oil change at 5,000 km (3,000 mi) from last oil change. Initiate removal procedures by using a diagnostic tool to obtain and mark down the current engine oil life percentage before unplugging the negative battery terminal. To replace the ecm it is necessary to separate the engine harness connector retainer locks so that you can disconnect the connectors from the module. Drain the ecm out of its bracket by detaching the bracket retainer tabs from the bracket. Install the ecm by slotting its bottom into the ecm bracket tab until it secures then mate the engine wiring harness electrical connectors before engaging their retainers. Completion of the task requires reattaching the negative battery terminal while instructing the ecm programming process when installing a fresh component.
