Passenger Airbag Circuit Short to Ground
Passenger airbag circuit has a fault causing a short to ground.
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 seeing a problem in the passenger airbag circuit, likely due to a wire touching metal and causing a short. This could prevent the airbag from deploying in a crash.
What the computer is actually seeing
The airbag control module detects an unexpected low resistance in the passenger airbag circuit, indicating a short to ground. The system is constantly monitoring for open and short circuits, using around 5 volts reference voltage.
What a healthy reading looks like
The passenger airbag circuit should show a resistance greater than 5 ohms; anything lower indicates a short.
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 passenger airbag wiring and connector for visible damage or corrosion. Decision: Repair or replace if damaged. If fine, move to step 2.
- 22. Check the resistance in the airbag circuit at the connector with a multimeter. It should be over 5 ohms. Decision: If it's below 5 ohms, suspect a short. Move to step 3, otherwise check the airbag module.
- 33. Perform a continuity test from the airbag connector back to the airbag control module. Look for shorts on the wiring harness. Decision: If continuity is present when it shouldn't be, repair the shorted wiring. If okay, replace the airbag module.
Common causes
- Damaged wiring harness or connector
- Moisture entry causing corrosion
- Faulty airbag module
