2006 Chevrolet Colorado Engine Control Module Parts and Q&A

• Q: What does the service of the engine control module (ECM) typically involve on 2006 Chevrolet Colorado?

  A: The powertrain control module (Pcm) service requires either replacement of the Pcm or eeprom programming. Check the Pcm for correctness prior to installation of the new part. A new service Pcm requires installation after confirming the faulty Pcm. A scan tool should be used first to extract and log the engine oil life percentage because this data needs to be included during programming the new module. Failure to perform this step results in 100% default oil life triggering an immediate 5000 km (3,000 mi) oil change from the previous service interval. Disconnect the Pcm harness connectors from the Pcm when the ignition is off to stop possible internal damage. The Pcm connector surfaces should be checked for dirt particles and the connector gaskets need verification for correct installation to avoid foreign material entry. Detach the mounting tabs from the Pcm bracket during Pcm removal because contact with either connector pins or soldered components leads to electrostatic discharge (Esd) damage. After placing the Pcm into its mounting bracket so tabs completely engage the user must connect the Pcm harness connectors to the body section. The installation of a new Pcm will require appropriate programming.
