Frequently asked questions
What does B0102 mean on a Jeep?
B0102 stands for "Electronic Side Sensor Malfunction." 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. On Jeep it is documented across 1 model: Grand Wagoneer.

The most common causes of B0102 are: 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).
