Code B3150 2014 GMC Sierra Description

The Body Control Module (BCM) monitors the voltage level of the door lock and door unlock signal circuits. When the driver door lock switch is in the open position, the voltage level in the signal circuit will be near 12 V. When the driver door lock switch is pressed to the lock or unlock position, the voltage level in the appropriate signal circuit will drop to 0 V and the BCM will detect the voltage drop and command the door latches to perform the requested lock or unlock command. The Diagnostic Trouble Code (DTC) will be set when the BCM detects a short to ground in the switch circuit.
