Code B11D8 Lincoln Description

The Battery Energy Control Module (BECM) monitors the impact notification output from the Restraint Control Module (RCM). The RCM outputs a Pulse Width Modulation (PWM) voltage on the circuit based on status. If the BECM senses the frequency is out of range, will illuminate the powertrain malfunction (wrench) warning indicator and set a Diagnostic Trouble Code (DTC).

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.
