B009CLeft Side Restraints Sensor 6
- Generic OBD-II code · Body
- How the car detects it
- B009C is the sixth and last left-side slot in the J2012 sensor block. No carmaker documents this code publicly. Real vehicles show how many side satellites are usual: FCA's 2019 Jeep Cherokee recall 19V-449 lists two engine bay sensors and four for B- or C-pillar positions, three per side at most, and FCA files those pillar units as B2761 to B2765 rather than in the B009x block. A sixth left sensor would therefore suit only long vans, buses or vehicles with several rear rows, where Bosch's option of satellites in the rear body also fits. If B009C appears, check first which sensor the maker assigns to it; a scan tool reading on a car with fewer sensors may point to a wrong module configuration. The airbag lamp lights.
