What Does the B1123 Lincoln Code Mean?
The Battery Energy Control Module (BECMB) provides battery voltage to the Restraints Control Module (RCM) and, if equipped, Passenger Airbag Deactivation (PAD) indicator (vehicles without center stack display only). The BECMB monitors each circuit for a short to voltage or a short to ground. If a fault is detected, the BECMB stores the appropriate Diagnostic Trouble Code (DTC) in memory and sends a message to the RCM over HS-CAN1 and HS-CAN2, indicating that a BECMB fault is present.
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.
