First: Disconnect Negative Battery Cable from Battery, so that there is no power to the electrical system at all!
The bcm is located on the back side of the under-dash fuse box (junction block). You remove the lower steering column cover and knee blocker reinforcement. Then remove two plugs from the bottom of the bcm.
Remove the bolts holding the junction block to dash panel mounting bracket. Remove the junction block from the bracket. Remove screws holding the bcm to the junction block. Slide the bcm downward to disengage guide studs on junction block from channels on bcm mounting bracket
Remove bcm from junction block.
