12. The MIP/LOCK fuse supplies battery positive voltage for the power mirrors, power door lock switches and the memory seat switch (if equipped). If the MIP/LOCK fuse is open, all Systems on the fuse would be inoperative. The fault could be a short to ground in the battery positive voltage circuit, however, a short to ground in the power mirror motor control or the memory seat control circuits could also be the cause if the fuse opens after any of the switches are activated. If a short to ground exists in either the door lock or unlock relay control circuits, a DTC (B3137 or B3147) would set when the BCM commands a lock or unlock function.
