B0102 on Jeep
Electronic Side Sensor Malfunction
B0102 on Jeep vehicles indicates electronic side sensor malfunction. Au7o has documented this code across 1 Jeep model — most commonly on Grand Wagoneer. This body/safety code indicates a malfunction with an electronic crash sensor used by the airbag (SRS) system, typically a frontal or side impact sensor on one side of the vehicle. The airbag control module continuously checks these sensors so it can deploy airbags and tensioners correctly in a crash, and it sets this code when a sensor reports an incorrect identity, fails, or its circuit is faulty. The airbag warning light will usually be on. Because it can compromise crash protection, it should be diagnosed promptly.
Common Causes of B0102
- •Faulty electronic side/frontal impact sensor
- •Open, shorted, or damaged sensor wiring harness
- •Corroded or loose sensor connector
- •Wrong or incompatible replacement sensor installed
- •Damage from a prior collision or water intrusion
- •Poor ground or connection in the SRS circuit
- •Faulty airbag control module (less common)

Multiple safety recalls affect the Grand Wagoneer airbag system. Recall 21V-873: The Occupant Restraint Controller (ORC) may have incorrect software that disables driver, passenger, and knee airbags. Recall 23V-545: The upper B-pillar interior trim may not be fully seated and could interfere with side curtain airbag deployment. Both issues prevent airbags from deploying properly in a crash.
