2005 Chevrolet Colorado Engine Control Module Parts and Q&A

• Q: What does the service of the engine control module (ECM) typically involve on 2005 Chevrolet Colorado?

  A: The service of a powertrain control module (Pcm) includes two main approaches: either pcm replacement or eeprom electrically erasable programmable read-only memory programming. The pcm requires an inspection to confirm the correct replacement component will be installed. The next step is to remove the failing pcm before you install the newly obtained service pcm. First scan the tool to obtain engine oil life percentage for programming the new replacement module because inadequate data entry will cause default settings to set oil change intervals at 5000 km (3,000 mi). The disconnect process for pcm harness connectors should happen with ignition off to avoid harming internal components. Before connector installation examine the pcm connector surfaces while checking that each gasket is properly installed to avoid contaminant entry. You should disconnect the pcm bracket mounting tabs during pcm removal but keep away from connector pins or soldered components to stop possible electrostatic discharge (Esd) harm. To install the unit place the pcm inside its bracket while making sure the tabs properly interlock before connecting the pcm harness connectors to the body of the pcm. Programming of new pcm units is mandatory after new pcm installation.
