B2A0A on Nissan
Body/Restraint Control Circuit Fault (manufacturer-specific)
B2A0A on Nissan vehicles indicates body/restraint control circuit fault (manufacturer-specific). Au7o has documented this code across 1 Nissan model — most commonly on Pathfinder. 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. Typical repair costs on Nissan range from $150 to $1,200, depending on the specific model and root cause.
Common Causes of B2A0A
- •Out-of-range or invalid sensor/switch signal in a body circuit
- •Damaged wiring or chafed harness
- •Corroded or loose connector
- •Failed body/control module
- •Internal module fault
- •Manufacturer-specific subsystem fault (confirm with service data)

- Rearview Camera Black Screen, Freezing, or Intermittent Image Loss2021-2025
Owners have documented backup camera failures including a black screen, frozen image, delayed display, or intermittent loss of the rear image when shifting into Reverse. Rear visibility system complaints are common enough across Nissan products that Nissan has issued service guidance and recalls on camera display behavior in related applications, and Pathfinder owners report the same symptom set on owner forums and NHTSA. Because the rearview camera is a federally required safety feature, even intermittent operation is significant.
