Does not lock or unlock, 4 other doors do work, no 12vdc going to lock coil, could the bcm module next to this be the problem

According to my wiring diagram there is a liftgate module mounted in the center of the lift gate. See if this controller is getting power in adn out, if in but no out it may be bad. This controller uses serial data line from the BCM to tell it what to do.
