Frequently asked questions
What does B0101 mean on a Jeep?
B0101 stands for "Electronic Frontal Sensor 2 Malfunction." This is a safety-system (SRS/airbag) code, so it should be taken seriously. Modern cars use frontal impact sensors that detect a crash and tell the airbag control module when and how to deploy the airbags. B0101 indicates the airbag (SRS) control module detected a malfunction or circuit fault with frontal impact sensor 2 — meaning the sensor or its wiring isn't reporting correctly, so the module may not be able to rely on it in a collision. This typically lights the airbag warning lamp and can disable airbag deployment until repaired, which is a genuine safety risk in a frontal crash. Note this is a manufacturer-specific code, so the exact sensor location and meaning can vary by make. On Jeep it is documented across 1 model: Grand Wagoneer.
What are the most common causes of B0101?
The most common causes of B0101 are: Failed front impact/frontal crash sensor (sensor 2), Damaged, corroded or unplugged sensor wiring/connector, Connector or wiring damage from a prior collision or repair, Water intrusion or corrosion at the sensor connector, Poor ground or open circuit to the sensor, Faulty airbag (SRS) control module, Sensor not properly seated or improperly mounted after service. The specific cause varies by vehicle.
