Airbag System Fault - Passenger Airbag Status Indicator Circuit
The airbag system has detected a fault in the passenger airbag status indicator circuit.
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 car's computer sees a problem with the circuit that shows whether the passenger airbag is on or off, which can prevent it from deploying in a crash.
What the computer is actually seeing
The system monitors the voltage signal from the passenger airbag status indicator circuit. A fault is indicated when the expected voltage does not match the required thresholds.
What a healthy reading looks like
The expected voltage at the airbag status indicator circuit should be between 0.5V to 4.5V. If the computer sees below 0.5V or above 4.5V, it will trigger a fault code.
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. Check the wiring and connectors at the passenger airbag indicator for any signs of damage or corrosion. Decision point: Are the connectors clean and intact? If yes, go to step 2. If no, repair or replace as necessary.
- 22. Measure the voltage at the passenger airbag status indicator circuit. Expected is 0.5V to 4.5V. Decision point: Is the voltage within range? If yes, go to step 3. If no, there’s a circuit fault; repair the circuit and clear the code.
- 33. Inspect the passenger seat occupancy sensor for proper operation. Check if it's connected and functional. Decision point: Does the sensor indicate correctly? If yes, replace the airbag status indicator module. If no, replace the occupancy sensor.
Common causes
- Damaged wiring or connectors in the airbag system
- Faulty passenger airbag status indicator module
- Defective passenger seat occupancy sensor

Frequently asked questions
Is it safe to drive with this code active?
No, it's not safe. The airbag may not deploy in an accident, so it should be fixed immediately.
Will this code come back after clearing?
If the underlying issue isn't fixed, yes, the code will likely return after clearing.
Why does this code sometimes pair with B1380?
B1380 indicates a fault with the driver's side airbag status, which can occur alongside passenger issues due to shared circuitry or common faults.
