• Q: How to replace the Body Control Module (BCM) on 2006 Buick Rainier?

  A: The Body Control Module replacement process requires the Ignition Switch to stay off while connecting and disconnecting connectors. Begin by detaching the 40-way body wiring extension and proceed to remove the 32-way tan connector before taking off the 24-way gray electrical connector. Connect first the 24-way gray electrical connector followed by the 32-way tan connector and finishing with the complete 40-way body wiring extension. The bcm monitors system operations even if you turn off the ignition and prevents the battery from losing power by detecting short circuits only for the courtesy lamps it manages. Activate the power down now mode through your scanner to detect any unwanted electricity use. All contacts of the body wiring extension must stay undisturbed while avoiding disassembly of the bcm housing which needs replacement as an entire unit. Start by taking off the device that grounds the battery. To substitute the bcm in a chevrolet trailblazer ext or gmc envoy xl you must detach the left second row seat and for a chevrolet trailblazer or gmc envoy you should reposition the left hand second seat toward a cargo space. Press and hold the locking tab of the rear electrical center cover. Push the bcm sliding latch toward the interior 1.6 inches until the unit detaches from its mount. Take off the bcm from its rear electrical center after detaching all 40-way body wiring extension, 32-way tan electrical connector and 24-way gray electrical connector. Places the slots of the bcm over the electrical center and pushes down to install it. Join the 24-way gray electrical connector, 32-way tan electrical connector, and 40-way body wiring extension to the bcm and secure the locking tab on the sliding latch by moving it outward once it reaches its full position. Replace the rear electrical center cover and arrange the left second seat for passenger use if necessary or reposition the second row seat in chevrolet trailblazer ext or gmc envoy xl vehicles. Finish by reconnecting the negative battery terminal and configuring the bcm during its replacement.
