B0098 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.
