Airbag Module - Internal Fault
The airbag control module detected an internal issue.
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)
Inside the airbag module, there’s a technical problem stopping it from working correctly, so it may not deploy the airbags in a crash.
What the computer is actually seeing
The airbag control module monitors internal circuitry and identifies faults based on preset thresholds for resistance and continuity. If a reading falls outside these thresholds, an internal fault code is triggered.
What a healthy reading looks like
Resistance values should typically be below 5 ohms and continuity should be confirmed for all internal connections.
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 for any visible damage to the airbag control module and its connectors. Are there signs of corrosion or loose connections?
- 22. Inspect the wiring harness for any frays or cuts. Is the integrity of the wiring intact?
- 33. Use a multimeter to measure the resistance of the airbag circuit. Are values consistently below 5 ohms?
- 44. Verify battery voltage and ground at the airbag module connector. Is voltage within 12-14 volts?
- 55. If all checks are normal and the code persists, replace the airbag control module and recheck for the code.
Common causes
- Faulty airbag control module
- Corrosion or damage in the airbag harness
- Poor connections at the module or sensors
- Voltage feed issues to the airbag system

Frequently asked questions
Is it safe to drive with this code present?
No, it’s a high severity code indicating the airbag system may not function, so driving is not safe.
Will this code come back after clearing?
If the underlying issue isn't fixed, yes, the code will likely return.
Why does it pair with other codes like B1067?
They indicate related faults within the airbag system, suggesting a broader issue with the module or wiring.
