- Damaged wiring or connectors in the passenger seat position sensor circuit
- Faulty passenger seat position sensor
- Malfunctioning airbag control module
- Corrosion or debris in the sensor connections
- Impact or physical damage to the passenger seat affecting sensor performance
Symptoms of B0080:08
- Airbag warning light illuminated on the dashboard
- Inconsistent or erratic airbag deployment
- Passenger seat belt reminder not functioning properly
- Inability to adjust passenger seat position electronically
- Diagnostic trouble code B0080:08 stored in the vehicle's computer system
How to Fix B0080:08
- Begin by conducting a thorough visual inspection of the wiring and connectors in the passenger seat position sensor circuit to check for any visible damage or corrosion.
- Test the passenger seat position sensor using a multimeter to determine if it is functioning properly or if it needs to be replaced.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
