Driver Airbag Circuit Open
The airbag control module detects an open circuit in the driver airbag.
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 airbag system has found that there's a break in the wiring or a connection issue preventing the driver airbag from working, which means it might not deploy in a crash.
What the computer is actually seeing
The airbag control module sees a voltage drop or no voltage at the driver airbag circuit when it checks during key-on or while running, indicating an open circuit.
What a healthy reading looks like
On a properly functioning system, the voltage at the driver airbag circuit should be around 2.5 to 3.5 volts when the ignition is on and the system is self-checking.
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 airbag indicator light on the dash; if it’s on, proceed to the next step; if not, this code may be inactive and check for intermittent issues.
- 22. Inspect the wiring and connectors leading to the driver airbag; look for any signs of wear, damage, or corrosion.
- 33. With the ignition off, check the continuity of the driver airbag circuit using a multimeter; you should see a complete circuit (close to 0 ohms). If it's open, repair the wiring.
- 44. Power up the system and check the voltage at the driver airbag connector; it should be between 2.5 to 3.5 volts. If not, further investigate the airbag control module.
- 55. If all wiring and connections are good, and voltage readings are correct, replace the driver’s airbag module.
Common causes
- Damaged wiring harness
- Loose or corroded connectors
- Faulty driver airbag module
- Damaged airbag itself
Typical repair cost

Will this code come back if I clear it?
If the underlying issue isn't fixed, yes, the code will return.
Why does this code appear with other airbag codes?
Airbag codes often trigger together, indicating broader system issues.
