Code B0080:04 Description
The B0080:04 code indicates that there is an open circuit in the passenger seat position sensor. The seat position sensor is responsible for determining the position of the passenger seat, which is crucial for the proper deployment of the airbag in case of a collision. An open circuit means that there is a break or discontinuity in the electrical connection within the sensor circuit, preventing it from accurately transmitting data to the airbag control module. This can potentially result in the airbag not deploying or deploying incorrectly, posing a safety risk to the vehicle occupants.
Common Causes of B0080:04
- Damaged wiring or connectors in the seat position sensor circuit
- Corrosion or moisture ingress affecting the sensor components
- Faulty passenger seat position sensor module
- Impact damage to the passenger seat affecting the sensor's operation
- Electrical issues within the vehicle's wiring system
Symptoms of B0080:04
- Airbag warning light illuminated on the dashboard
- Passenger airbag light indicating that it is deactivated
- Inconsistent or non-deployment of the passenger airbag during a crash
- Intermittent beeping sound or warning message related to the airbag system
- Loss of communication with the passenger seat position sensor module
How to Fix B0080:04
- Begin by diagnosing the specific cause of the open circuit using a diagnostic scanner to retrieve fault codes and pinpoint the issue.
- Inspect the wiring and connectors of the passenger seat position sensor for any damage, corrosion, or loose connections. Repair or replace as necessary.
- Test the sensor module itself for functionality and replace if found to be faulty.
- Clear the diagnostic trouble codes from the airbag control module using a scanner after the repair is completed.
- Perform a final test to ensure that the passenger seat position sensor is now functioning correctly and that the airbag system is operational.
Cost to Fix B0080:04
The cost of repairing a B0080:04 code can vary depending on the specific cause of the issue and the labor rates in your area. On average, the repair cost for this type of problem can range from $150 to $500, including parts and labor. It's important to consult with a professional mechanic to get an accurate estimate tailored to your vehicle's make and model. Keep in mind that additional diagnosis time or parts replacement may incur extra costs.

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.
