B0029Right Curtain Deployment Control 1
- Generic OBD-II code · Body
- How the car detects it
- B0029 stands for the first firing loop of the right curtain airbag. FCA's STAR case S2010000001 for the 2019 Ram heavy-duty pickup reads B0029-11 as a ground short in right curtain squib 1 and sends the technician to the wiring at the C-pillar trim fixings. Mitsubishi lists the right curtain module under B0029 and sets the ground short after 2 seconds. On the A-Class, CLA and GLB Mercedes-Benz stores B002913 for an open squib of the right window bag. Older GM modules used the number for the passenger side airbag: the 2006 Saab 9-5 sets it when resistance stays above 4.5 ohms for 2 seconds. B002A is the second right curtain loop. Airbag lamp on; the curtain may not deploy in a side impact or rollover.
