The cost to diagnose the B130C code is 1.0 hour of labor. The diagnosis time and labor rates at auto repair shops vary depending on the location, make and model of the vehicle, and even the engine type. Most auto repair shops charge between $75 and $150 per hour.
The trailer battery charge relay coil receives voltage from the Battery Junction Box (BJB) fuse when the ignition is in RUN. The BJB fuse supplies voltage to the Trailer Battery Charge Relay switch side at all times. The Body Control Module (BCM) controls the ground side for the battery charge relay coil.
The BCM provides ground for the trailer battery charge relay when the ignition is in RUN and the BCM determines that the battery voltage is not low. When the trailer battery charge relay is energized, the voltage is routed to the trailer tow connector.
