Airbag Deployment Circuit Failed
The airbag system detected a failure in the 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 system is saying there's a problem with the circuit that makes the airbag deploy. It might not go off in a crash, which is dangerous.
What the computer is actually seeing
The airbag control module monitors resistance in the deployment circuit. It expects to see specific resistance values indicating the circuit is working. If the resistance is too high or too low, it sets the code.
What a healthy reading looks like
Normal resistance should typically be between 2.5 to 5 ohms in the deployment circuit.
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.
- 1Check for obvious wiring damage or loose connectors between the airbag control module and the airbag itself.
- 2Inspect the airbag connectors for corrosion or bent pins.
- 3Measure the resistance of the deployment circuit; it should be between 2.5 to 5 ohms. If readings are outside this range, repair the circuit accordingly.
- 4If wiring and connectors are good and resistance is normal, check the airbag module itself for faults.
Common causes
- Damaged wiring or connectors in the airbag circuit
- Faulty airbag module
- Open circuit in the airbag deployment system
- Corrosion at connector terminals

Frequently asked questions
Is it safe to drive with this code set?
No, it's not safe. If the airbag system fails, airbags may not deploy in a crash.
Will this code come back after clearing it?
If the underlying issue isn’t fixed, it will come back after clearing.
Why are related codes also appearing?
Related codes can indicate other issues in the airbag system, which may compound the problem.
