Driver's Airbag Circuit Malfunction

The computer sees a fault in the wiring or components that control the driver's airbag. This can mean the airbag won’t deploy in a crash, risking safety.

The airbag control module monitors the resistance in the driver’s airbag circuit. It expects a certain resistance value (typically around 2-3 ohms) when everything is functioning correctly. If the resistance is too high or too low, it triggers this code.

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.

1. 11. Inspect the driver’s airbag connector and wiring for visible damage or corrosion. If damaged, repair or replace as needed. Decision Point: Did you find damage?
2. 22. Check the resistance of the driver’s airbag circuit using a multimeter. Unplug the airbag, and measure across the terminals. Expected range is 2-5 ohms. Decision Point: Is the resistance within the expected range?
3. 33. If resistance is out of range, replace the airbag module. If within range, check for any faults in the steering wheel clock spring. Decision Point: Is the clock spring functioning correctly?
4. 44. If all else checks out, clear the code and test drive. Monitor for repeat codes.

• Damaged wiring harness
• Faulty airbag module
• Defective airbag sensor
• Corroded connectors
• Expired airbag assembly
