Code B1BC7 Mitsubishi Description

The B1BC7 Mitsubishi code indicates that the Deployment Data Record is full. This code is typically associated with the vehicle's airbag system, specifically the restraint control module (RCM). The RCM is responsible for monitoring various sensors throughout the vehicle to deploy the airbags in the event of a collision. The Deployment Data Record is a log that stores information about the airbag system's deployment history, including crash data and diagnostic trouble codes.

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.
