OBD2 Body Control (B-Codes) Master Index B-Codes are OBD2 body-system diagnostic trouble codes used to identify faults involving vehicle body electronics and related control systems. Depending on the vehicle manufacturer, B-Codes may involve Airbag/SRS , seatbelt pretensioners, occupant detection, Body Control Modules (BCM) , instrument clusters, climate control, lighting, anti-theft systems, and other body-related circuits. This B-Code Master Index organizes OBDSpark diagnostic guides by code range, making it easier to find the correct fault-code procedure and understand the systems commonly associated with each group. Important: B-Code definitions and diagnostic procedures can vary significantly between manufacturers. Always verify the exact code description, wiring configuration, module designation, and test procedure for the specific vehicle.
