|What are the Possible Causes of the B13BF MERCURY Code?
Faulty Battery Energy Control Module (BECMB)
Battery Energy Control Module (BECMB) harness is open or shorted
Battery Energy Control Module (BECMB) circuit poor electrical connection
|How to Fix the B13BF MERCURY Code?
Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
|What is the cost to diagnose the B13BF MERCURY code?
The cost to diagnose the B13BF MERCURY code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.

|What Does the B13BF MERCURY Code Mean?
The Battery Energy Control Module (BECMB) provides battery voltage to the Restraints Control Module (RCM) and Occupant Classification System Module (OCSM). The BECMB compares HS-CAN1 messages to ignition voltage inputs. If the status of the HS-CAN1 message and the voltage input do not match, the BECMB sets a Diagnostic Trouble Code (DTC). A fault is indicated when the hard-wired ignition input to the BECMB is inactive, but the BECMB receives an ignition status on the HS-CAN1 that contradicts the hard-wired input status.
Run/Start Input Circuit Short to Ground Or Open

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed,
it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
