2007 GMC Canyon Parts Questions & Experts Answers

• Q: What does the service of the engine control module (ECM) typically involve on 2007 GMC Canyon?

  A: The normal servicing procedures for powertrain control module (PCM) consist of replacing the PCM unit or performing EEPROM programming. A correct part check of the PCM needs to happen before implementation of a new PCM. Users should first verify the faulty component then proceed to replace it with the new service PCM. Turn the ignition OFF always during control module connector work or power connection and disconnection tasks because internal damage can occur. The metal case of the control module needs to stay away from any contact with battery voltage because such contact might harm the system. Electrostatic discharge damage can be prevented by refraining from touching connector pins and soldered components located on the circuit board. Examine the connector gaskets that should be properly installed to block contaminants. At the same time remove any debris from the control module connector surfaces. The process of programming the replacement control module is crucial because failure to record the engine oil life percentage will automatically reset the oil change interval to 5000 km (3,000 mi) from the last service. Start the removal process through a scan tool which enables retrieval of the current engine oil life percentage data for recording purposes. Disconnect the PCM harness connectors from the PCM while being careful to minimize contact with pins that avoid electrostatic damage. Remove the PCM by detaching the mounts of its bracket and unfastening the PCM bracket mounting tabs. Install the PCM by positioning it into the mounting bracket where tabs must fully connect and then connecting PCM harness connectors to the PCM body . Programming is required whenever installing a new PCM.
