Code B3130 Chevrolet Description

The Body Control Module (BCM) supplies a 12-volt signal to the lock and unlock signal circuits of the driver and passenger door lock switches. When the appropriate switch is pressed, a contact within the door lock switch closes providing a ground path for the signal circuit. The BCM will detect the voltage drop in the signal and will command the doors to perform the lock or unlock functions. The BCM may also receive a LOCK or UNLOCK command from the Keyless Entry Control Module.
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.
