Driver Side Airbag Circuit High Resistance
There's a problem in the driver side airbag circuit, indicating high resistance.
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 side airbag isn't communicating properly, likely due to a break or poor connection in the wiring.
What the computer is actually seeing
The airbag control module detects higher than normal resistance in the driver side airbag circuit, which could prevent the airbag from deploying in a crash.
What a healthy reading looks like
Resistance should be less than 5 ohms; anything above that indicates a problem.
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 the driver side airbag wiring harness for visible damage or corrosion. If damaged, repair or replace the wiring.
- 22. Check the connector at the driver side airbag for corrosion and proper seating. Clean and re-seat if necessary.
- 33. Use a multimeter to measure resistance at the airbag connector. If resistance is above 5 ohms, further diagnosis is needed; otherwise, the problem might be elsewhere.
- 44. If resistance is high, trace the wiring back to the airbag control module and check for continuity. Repair any breaks.
- 55. If all wiring checks out, consider testing or replacing the airbag module. Ensure to follow safety procedures for airbag handling.
Common causes
- Damaged wiring harness
- Poor connection at airbag plug
- Defective airbag module

Frequently asked questions
Is it safe to drive with this code?
It's not recommended to drive with a B1988 code as the airbag may not deploy in an accident.
Will this code come back after clearing?
If the underlying issue isn't fixed, the code will likely return after clearing.
Why does this code show up with others?
Often, multiple codes occur because the airbag system shares wiring or components that can affect more than one circuit.
