B0023 code meaning
Left Side Deployment Stage 1 Loop Short to Ground
What B0023 means
B0023 does not appear in the J2012 code lists, which jump from B0022 to B0028, and no carmaker documents it as a ground short of a left side airbag stage. It is documented at General Motors with another meaning: in the Saab 9-4X 2011 manual B0023 is the right roof rail (curtain) airbag loop, with bytes for short to battery (01), short to ground (02), open (04) and resistance above 4.2 or below 1.4 ohms (0D, 0E), each confirmed after 2 seconds. GM bulletin 08-09-41-002H lists B0023 among codes caused by unseated connector position locks on many 2005-14 models. A real ground short in a squib loop can stop deployment, so first read which module and descriptor the scan tool reports. Airbag lamp on.

Common causes of B0023

Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of B0023 means

| 0 | Generic code: it means the same on every make (SAE standard). |
| 23 | The exact fault in that area. |
What to do next
- Note B0023 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
