Faulty Passenger Airbag Status Indicator Circuit
Indicates an issue with the passenger airbag 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 is detecting a problem in the wiring or sensor that shows whether the passenger airbag is on or off. This could mean the airbag might not work correctly in a crash.
What the computer is actually seeing
The airbag control module monitors the circuit for the passenger airbag status indicator. It expects to see a voltage of around 5 volts from the indicator when operating normally. If it sees less than 2 volts or greater than 6 volts, it sets this fault code.
What a healthy reading looks like
Normal operation should show 5 volts at the indicator circuit when the airbag is active. Off state should read close to 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. Verify the vehicle's airbag system integrity using a scan tool to check for additional codes.
- 22. Inspect the wiring and connectors for the passenger airbag indicator for damage or corrosion. Fix any issues found and retest.
- 33. Check the voltage at the passenger airbag status indicator circuit with a multimeter. If voltage is outside expected values, proceed to the next step.
- 44. Replace the indicator bulb in the airbag status indicator circuit if it is burnt out or defective. Retest system after replacement.
- 55. If the issue persists, check the airbag control module for faults. Consult manufacturer guidelines for specific testing procedures.
Common causes
- Damaged wiring or connectors in the airbag system
- Faulty passenger airbag status indicator bulb
- Defective airbag control module
- Loose or corroded connectors
- Previous collision repairs affecting the airbag system

Frequently asked questions
Is it safe to drive with this code active?
Yes, but the passenger airbag may not deploy in an accident, risking safety.
Will this code return after clearing it?
If the underlying issue is not fixed, the code will likely return.
Why does this code come with other codes?
Airbag systems often have multiple sensors and indicators that can fail together.
