Front Passenger Seat Belt Switch Circuit Open
The front passenger seat belt switch circuit is open or has a fault.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The computer is checking if the passenger seat belt is fastened. If it finds an open circuit, it thinks the seat belt isn't clicked in, even if it is.
What the computer is actually seeing
The body control module (BCM) expects a closed circuit (5 volts typically) from the seat belt switch when buckled. If it sees an open circuit, it triggers the fault code.
What a healthy reading looks like
Closed circuit should be around 5 volts; open circuit is 0 volts.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Inspect the seat belt switch connector for damage or corrosion. If damaged, repair or replace it.
- 22. Check the wiring from the seat belt switch to the BCM for breaks or shorts. Repair if necessary.
- 33. Test the seat belt switch with a multimeter. It should show continuity (close to 0 ohms) when buckled. If not, replace the switch.
- 44. Clear the code and test drive the vehicle. If the code returns, further diagnose the BCM or related circuits.
Common causes
- Faulty passenger seat belt switch
- Damaged wiring or connectors in the seat belt circuit
- Corrosion or dirt in the connector
- Open circuit due to a broken wire

Will this code come back after clearing?
Yes, if the fault still exists in the circuit.
Why does this code pair with others?
Because multiple seat belt or airbag faults can occur in the same system.
