Driver Side Airbag Deployment Circuit Open
Airbag deployment circuit for the driver side is open or has a fault.
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 system that's supposed to deploy the driver's airbag has a problem. This could be a broken wire or a bad sensor, and it means the airbag won't work in a crash, which is dangerous.
What the computer is actually seeing
The airbag control module looks for a consistent electrical signal from the airbag circuit. If this signal is interrupted or missing, it sets a fault indicating an open circuit.
What a healthy reading looks like
Expected resistance in the airbag circuit should be less than 5 ohms; voltage supply should be around 12 volts when the system is powered.
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 wiring and connectors of the driver's airbag module for any visible damage or corrosion. If found, repair the wiring or replace connectors.
- 22. Check the resistance of the airbag circuit with a multimeter. It should be less than 5 ohms. If it’s higher or open, track down the break in the wiring.
- 33. Use a scan tool to clear the code and see if it comes back. If it does, the issue is likely in the airbag control module or an unrepairable circuit fault.
- 44. If all wiring checks out, replace the airbag control module, as it may be defective.
Common causes
- Broken or damaged wires in the airbag circuit
- Loose or corroded connectors
- Faulty airbag control module

Will this code come back after resetting it?
Yes, if the underlying issue isn’t fixed, the code will likely return after resetting.
Why does this code appear with other airbag-related codes?
These codes often point to similar wiring or connector issues in the airbag system, so they tend to show up together.
