Most Reported On
B3130 is an OBD-II diagnostic trouble code meaning “All Doors Unlock Circuit Malfunction.” B3130 is a body code, commonly defined on GM/Opel-family vehicles as a malfunction in the all-doors-unlock circuit. The body control module monitors and drives the door lock control circuits, and it sets this code when it detects a short to battery, short to ground, or open in the circuit that unlocks all doors. The typical result is inoperative power door locks for the all-unlock function; it is a convenience-system fault rather than a safety concern. This code is most commonly reported on 2007-2013 GMC Sierra 1500, with repair costs ranging from $180 to $500.
