Passenger Airbag Status Indicator Circuit Short To Ground
Indicates a short circuit 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 computer thinks there’s a problem because the wire that tells it if the passenger airbag is ready is shorted to ground, causing incorrect readings.
What the computer is actually seeing
The airbag control module detects a voltage drop or a constant low voltage (near 0V) on the indicator circuit when it should see a normal operating voltage, typically between 5V and 14V.
What a healthy reading looks like
Expected voltage on the airbag status indicator circuit should be around 5V when the airbag is not deployed and around 0V when deployed.
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. Visually inspect the wiring and connectors for the passenger airbag status indicator. Check for damage or corrosion.
- 22. Use a multimeter to measure the voltage on the airbag status indicator circuit; it should be around 5V with the ignition ON and the airbag not deployed.
- 33. If the voltage is near 0V, check for continuity to ground; isolate the circuit to find where the short occurs.
- 44. If wiring checks out, test the passenger airbag status indicator lamp by removing it and measuring resistance; replace if it's faulty.
- 55. If all tests are good but the code persists, consider replacing the airbag control module.
Common causes
- Damaged wiring in the airbag status indicator circuit
- Faulty passenger airbag status indicator lamp
- Corrosion at connectors or terminals
- Unplugged or poor connection at the airbag module
