Airbag Circuit Malfunction
Issues detected in the airbag 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 has found a problem with the wiring or components that make the airbag system work, which could prevent the airbags from deploying in a crash.
What the computer is actually seeing
The airbag control module monitors resistance in the airbag circuit. It expects to see specific resistance values for the airbags and their connections; if the values are too high or too low, a fault code is set.
What a healthy reading looks like
Expected resistance for airbag circuits should range between 2 to 5 ohms. If resistance is outside this range, a fault is detected.
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.
- 1Inspect the airbag system wiring and connectors for visible damage.
- 2Check DTCs for additional Airbag-related codes.
- 3Using a multimeter, measure resistance at the airbag connector; should be 2-5 ohms.
- 4If resistance is out of range, repair or replace the wiring or connector as needed. If within range, suspect the airbag module.
Common causes
- Damaged wiring
- Faulty airbag module
- Open circuit in connector
- Faulty airbag sensor or deployment circuit
Typical repair cost
$$$ - $$$$
