B0092Left Side Restraints Sensor 2
- Generic OBD-II code · Body
- How the car detects it
- B0092 belongs to the second crash sensor on the left side. Mitsubishi fits it at the left B-pillar and lists it as B-PILLAR SAT SEN LH, adding the J2012 title Left Side Restraints Sensor 2; its index shows only subtype -55, set two seconds after the unit finds that its stored configuration does not fit the vehicle. A pillar position suits an acceleration satellite: Bosch mounts these on stiff members such as sills, seat cross members or B- and C-pillars, and its SMA773 chip measures two axes up to 60 g and talks to the module over a two-wire PSI5 link. GM-built Saabs use the number differently: the 2006 9-5 and the 9-3 store B0092 for a general fault of the passenger presence system, with the airbag system then rated out of order. The airbag lamp is on.
