How to service the Engine Control Module (ECM) on Chevrolet Tahoe?

The service of Engine Control Module (ECM) requires either a new ecm installation or eeprom programming. Verifying that the replacement ecm serves as the correct component is necessary before unhooking the damaged ecm for new service ecm installation. Warning: turn the ignition off before dealing with control module connectors because it helps defend against internal damage to the components. The metal case of control modules should stay away from battery voltage while keeping your fingers off both pins and solder joints to block electrostatic discharge. Check the control module connector surfaces for debris before inspecting gaskets to ensure proper installation and contamination prevention. The new control module requires programming and a recording of engine oil life must happen because failure to do so will set engine oil life to 100 percent which forces an oil change at 5000 km (3000 mi) from last maintenance. The process starts with scanning the tool to measure engine oil life percentage then remove the negative battery terminal. Remove the ecm connectors by disconnecting their retainers from the engine wiring harness electrical connector. Workers need to detach the bracket retainer tabs that lock the ecm to the bracket in order to pull the ecm free from the bracket. To set up the ecm installation begin by slotting the bottom part into the ecm bracket tab then push the device firmly to fasten it before connecting the retainers on the engine wiring harness electrical connectors. When completed connect the negative Battery Cable while performing an ecm program if the system added a new ecm.

Q: How to service the Engine Control Module (ECM) on Chevrolet Tahoe?
A:
The service of Engine Control Module (ECM) requires either a new ecm installation or eeprom programming. Verifying that the replacement ecm serves as the correct component is necessary before unhooking the damaged ecm for new service ecm installation. Warning: turn the ignition off before dealing with control module connectors because it helps defend against internal damage to the components. The metal case of control modules should stay away from battery voltage while keeping your fingers off both pins and solder joints to block electrostatic discharge. Check the control module connector surfaces for debris before inspecting gaskets to ensure proper installation and contamination prevention. The new control module requires programming and a recording of engine oil life must happen because failure to do so will set engine oil life to 100 percent which forces an oil change at 5000 km (3000 mi) from last maintenance. The process starts with scanning the tool to measure engine oil life percentage then remove the negative battery terminal. Remove the ecm connectors by disconnecting their retainers from the engine wiring harness electrical connector. Workers need to detach the bracket retainer tabs that lock the ecm to the bracket in order to pull the ecm free from the bracket. To set up the ecm installation begin by slotting the bottom part into the ecm bracket tab then push the device firmly to fasten it before connecting the retainers on the engine wiring harness electrical connectors. When completed connect the negative Battery Cable while performing an ecm program if the system added a new ecm.
