Driver Side Airbag Circuit Short to Ground
The airbag system has detected a problem with the driver side 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)
There's a short in the wiring for the driver side airbag, meaning the system sees a constant low signal where it expects a handoff during airbag operation.
What the computer is actually seeing
The airbag control module sees a voltage below 0.2 volts on the driver airbag circuit, indicating the circuit is grounded when it shouldn't be.
What a healthy reading looks like
The driver airbag circuit should have a steady voltage between 2.5 to 14 volts under normal conditions; anything below 0.2 volts triggers this fault code.
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. Inspect airbag connector and wiring under the driver seat for damage or corrosion. Fix any issues found.
- 22. Check the resistance of the driver airbag squib; should be around 2.0 to 3.5 ohms. If outside this range, replace the airbag.
- 33. Inspect for aftermarket modifications or repairs that might have disturbed airbag wiring. Repair as necessary.
- 44. Clear the code and see if it returns. If it does, repeat tests to isolate the short.
Common causes
- Damaged wiring or connector under the seat or in the dash
- Faulty driver airbag squib
- Corrosion in connector terminals
- Aftermarket seat installations or repairs interfering with the airbag circuits
Typical repair cost
$$ - $$$

Frequently asked questions
Is it safe to drive with this code active?
Not recommended. Airbags may not deploy in an accident, increasing the risk of injury.
Will this code come back after repairs?
If the short circuit is fixed properly, the code should not return.
Why does this code sometimes pair with B0099?
B0099 indicates a similar circuit issue, potentially leading to both codes being triggered if wiring errors exist.
