B0023Left Side Deployment Stage 1 Loop Short to Ground
- Generic OBD-II code · Body
- How the car detects it
- 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.
