Driver's Airbag Deployment Circuit Resistance Too High
The airbag control module has detected high resistance in the driver's airbag deployment 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 is saying there's a problem with the driver's airbag wiring or the airbag itself. That's why the light is on, and it might not deploy if there's an accident.
What the computer is actually seeing
The airbag control module monitors the resistance of the airbag circuit, which should typically be around 2 to 3 ohms. If the resistance rises above 5 ohms, this code gets triggered.
What a healthy reading looks like
Expected airbag circuit resistance should be between 2 to 3 ohms; anything above 5 ohms indicates a fault.
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 airbag wiring for any visible damage or wear. Check for cuts, pinches, or corrosion at connectors.
- 22. Use a multimeter to check the resistance of the airbag circuit. It should read between 2 to 3 ohms. If it's above 5 ohms, continue to the next step.
- 33. Check the connectors and pins on the airbag module for corrosion or loose connections. Repair as necessary.
- 44. If the wiring and connectors are good, swap the airbag module with an known good unit if available, then clear the code and retest.
Common causes
- Damaged airbag wiring harness
- Faulty airbag module
- Corroded connector terminals
- Open circuit in driver airbag
- Faulty airbag itself

Frequently asked questions
Is it safe to drive with this code active?
It’s best to have it fixed soon; the airbag may not deploy in an accident.
Will this issue come back after clearing the code?
If the underlying problem isn’t fixed, the code will likely reappear.
Why does this code show up with other codes about airbag performance?
Wiring issues can cause multiple airbag codes due to shared circuits or related components.
