2005 Chevrolet Astro Parts Questions & Experts Answers

• Q: How to service the Engine Control Module (ECM) on 2005 Chevrolet Astro?

  A: Both pcm replacement and eeprom programming serve as methods for powertrain control module service. The pcm needs inspection to verify that the correct component will be used prior to replacement. The next step requires changing the faulty pcm with a new service pcm after confirmation of its validity. The pcm experiences risk for internal damage when disconnecting or reconnecting power while running under fuel shutoff conditions with battery cables, pcm pigtails, pcm fuses, or jumper cables although power is off. Examine and clean the surfaces of the pcm connector and verify proper installation of pcm module connector gaskets since these components stop contaminants from entering. The new pcm needs computer programming before installation. Start the replacement process by unplugging the pcm harness connectors only when the ignition is turned off to safeguard the inside components. The pcm should be lifted off from its pcm mounting tray after releasing the spring latch . Mount the pcm into its designated tray while you fasten it there by pushing the spring latch. Connect the pcm connectors properly to the pcm while tightening the connector end fasteners to 8 n.m (71 lb in). New pcm installation will need proper programming following the procedure.
