B1034 on Nissan
Manufacturer-Specific Body / Restraint Circuit Fault
B1034 on Nissan vehicles indicates manufacturer-specific body / restraint circuit fault. Au7o has documented this code across 1 Nissan model — most commonly on Altima. B1034 is a manufacturer-specific body code whose exact meaning varies by automaker, so it cannot be tied to one universal definition; on GM-family vehicles it generally falls within the body/restraint (SIR) and accessory circuit range. Broadly, it indicates the body or airbag control module detected an electrical fault in one of its monitored circuits. A make-specific scan tool and service manual are required to confirm exactly which circuit and fault are involved before repair. Typical repair costs on Nissan range from $250 to $1,800, depending on the specific model and root cause.
Common Causes of B1034
- •Open or shorted wiring in the affected body/restraint circuit
- •Corroded, wet, or loose connector
- •Faulty component on the monitored circuit
- •Faulty body or airbag (SRS) control module
- •Poor ground or high-resistance connection
- •Harness damage from prior repair
- •Low or unstable system voltage

- Passenger Occupant Classification Sensor / Air Bag Warning Light Fault2007-2012
Multiple 2007-2012 Altima owners report the air bag warning light flashing and the passenger air bag status behaving incorrectly due to faults in the occupant classification system (OCS) or related seat sensor components. This can disable the passenger frontal air bag when it should be enabled, or trigger a persistent SRS warning light. Nissan issued service information and warranty extensions on some related OCS concerns because the issue was common enough to generate many complaints and dealer repairs.
