Driver Side Airbag Deployment Circuit Open
The airbag control module has detected an issue with the driver side 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 airbag computer can't see the driver airbag working properly, which means it won't deploy if you crash.
What the computer is actually seeing
The airbag control module monitors the resistance in the deployment circuit for the driver side airbag. If the resistance is outside the normal range (typically 2-3 ohms when connected), it throws this code.
What a healthy reading looks like
Resistance typically should be between 2-3 ohms when the airbag module is connected and not faulted.
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 connector under the driver's seat for secure connection. Is it connected? (Yes: proceed to step 2; No: reconnect and clear code)
- 22. Inspect the wiring harness for physical damage, especially near the connector. Is the wiring intact? (Yes: proceed to step 3; No: repair wiring and clear code)
- 33. Measure resistance of the airbag circuit at the connector. Is it within 2-3 ohms? (Yes: proceed to step 4; No: check for damaged components or replace airbag module)
- 44. Check if the vehicle has been in past collisions. If yes, verify if airbag deployment or replacement was done correctly. Was it done properly? (Yes: replace airbag module; No: follow proper deployment/replacement procedures)
Common causes
- Disconnected or faulty airbag connector
- Open circuit in airbag wiring harness
- Faulty airbag module
- Damaged airbag unit

Frequently asked questions
Is it safe to drive with this code?
No, the airbag may not deploy in an accident, which compromises safety.
Will this code come back after clearing it?
If the underlying problem isn't fixed, yes, it will reappear.
Why does this code pair with B0013?
B0013 indicates a problem with the passenger airbag circuit, so both codes can reflect issues with the airbag system wiring.
