Most Reported On
B2A0A is an OBD-II diagnostic trouble code meaning “Body/Restraint Control Circuit Fault (manufacturer-specific).” B2A0A is an obscure manufacturer-specific body code that is not reliably documented in public OBD-II references, so a specific definition cannot be confirmed. Based on its prefix it relates to a body system (commonly comfort, restraint, or control-module circuits) and generally indicates that the controlling module detected an out-of-range or invalid condition in a monitored circuit. The exact meaning must be confirmed against the specific vehicle make/model service information, and the severity depends on which subsystem (e.g. a restraint circuit would be high) the code actually addresses. This code is most commonly reported on 2021-2025 Nissan Pathfinder, with repair costs ranging from $150 to $1,200.
