B0081 on Chevrolet by model: symptoms, diagnosis and fix
A recurring safety complaint on this generation is failure of the passenger presence/occupant classification system in the front passenger seat. Owners report the air bag warning lamp, 'Passenger Air Bag Off' message when an adult is seated, or intermittent operation depending on seat position. The issue is tied to the seat sensor mat/module and related wiring/connectors, and it can disable proper passenger airbag deployment logic.
Common Symptoms
- air bag warning light illuminated
- Passenger Air Bag Off with adult in seat
- intermittent passenger airbag status
- warning changes when seat is moved
- service air bag message
How to Fix
Scan the SIR module for occupant classification and seat sensor faults, inspect under-seat connectors for tension or corrosion, and verify the system with a capable scan tool after repairs. Depending on the fault, repair may involve connector service, harness repair, or replacement/calibration of the passenger presence sensor assembly. Because this affects airbag operation, proper post-repair verification is essential.

Frequently asked questions
What does B0081 mean on a Chevrolet?
B0081 stands for "First Row Center Seatbelt Load Limiter Deployment Control (Subfault)." This is a supplemental restraint (SRS) code relating to the deployment control circuit for the first-row center seatbelt load limiter / pretensioner. The airbag control module monitors this restraint circuit and sets the code when it detects an electrical fault such as an open, short, or out-of-range resistance. Because it involves a crash-protection device, the airbag/SRS warning light typically illuminates and the related restraint may not deploy correctly in a collision. On Chevrolet it is documented across 1 model: Equinox.
What are the most common causes of B0081?
The most common causes of B0081 are: Open or shorted wiring in the load limiter / pretensioner circuit, Faulty or already-deployed restraint pretensioner, Corroded or loose connector at the seatbelt/restraint device, Damaged connector under the seat or in the floor harness, Faulty airbag (SRS/SDM) control module, Poor ground to the restraint system, Wiring damage from seat movement or moisture. The specific cause varies by vehicle.
