Driver's Airbag Circuit Open
A fault detected in the airbag system indicating an open circuit in the driver's airbag.
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 driver's airbag circuit is not completing properly, which means the airbag might not inflate in a crash. This can happen if the wiring is damaged or disconnected.
What the computer is actually seeing
The airbag control module detects an open circuit in the driver's airbag circuit, causing it to set a fault code and turn on the airbag warning light.
What a healthy reading looks like
Resistance in the airbag circuit should be less than 2 ohms when connected. If open, the reading will be infinite or very high.
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 visible damage to the wiring and connectors related to the driver's airbag.
- 2Inspect the airbag connector for loose pins, corrosion, or dirt.
- 3With the ignition off, measure the resistance across the airbag circuit; it should be less than 2 ohms when connected. If infinite or very high, proceed to the next step.
- 4Disconnect the airbag module, check for continuity in the airbag circuit harness, and look for breaks in the wires. If found, repair and retest.
- 5If the wiring and connectors are good, replace the airbag module as it may be faulty.
Common causes
- Damaged airbag wiring harness
- Faulty airbag connector
- Defective airbag module
- Corrosion on terminals

Will this code come back if I clear it?
If the underlying issue isn't fixed, the code will return after clearing.
Why did this code pair with another airbag code?
Multiple codes can appear if there are widespread issues in the airbag circuit or related components.
