Code B00D5 Mercury Description

The Restraints Control Module (RCM) is responsible for continuously monitoring all connections within the Supplemental Restraint System (SRS), including airbags and other safety-related components. If the RCM detects a device or connection that is either unrecognized, not stored in its memory, or not configured for the system, it will trigger a Diagnostic Trouble Code (DTC). Once the DTC is set, the RCM sends a message to the Instrument Panel Cluster (IPC), instructing it to illuminate the airbag warning light. This alert serves as a notification to the driver that there may be a fault within the SRS, which could affect the functionality of the airbags or other safety systems. Immediate inspection and repair are recommended to ensure the safety systems are functioning correctly.

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.
