Code B3135 2015 Chevrolet Silverado Description
The BCM, upon receipt of a lock switch lock or unlock signal, will supply voltage to the door lock actuator lock or unlock control circuits. Since the opposite side of the lock actuator is connected to the ground through the other lock actuator control circuit, the doors will then lock or unlock as commanded. The Diagnostic Trouble Code (DTC) sets when the BCM detects a short to ground or open/high resistance on a door latch control circuit.
