The first step in replacing the Body Control Module is disconnecting the negative Battery Cable. Take out the instrument panel insert to the left and unplug the bcm power wires. Gently lift the bcm and pull it out of the bracket slot. To install, insert the top of the bcm into its mounting bracket then, with support, fit the bottom into the corresponding slot. Attach the bcm electrical connectors, put back the left instrument panel insulator and fasten the negative Battery Cable. The last step is to program the new bcm.
