B0028Right Side Airbag Deployment Control
- Generic OBD-II code · Body
- How the car detects it
- B0028 is the right-hand twin of B0020: the firing loop of the right front side airbag, normally in the outer flank of the passenger seat. Honda asked for parts from 2018-20 Accord and CR-V and from the 2015 TLX that stored B0028-13, an open or raised resistance in the passenger side airbag inflator. FCA traces B0028-13 on the Cherokee and Chrysler 200 to the jumper harness in the seat, and Toyota's 2022 Tundra stored B002811 or B002812 because the wireless phone charger disturbed the module. Mitsubishi confirms a short to ground after 2 seconds. The older GM numbering differs: the 2006 Saab 9-5 and the 9-3 used B0028 for low resistance in the passenger side bag loop, under 1.5 ohms. Airbag lamp on.
