B0101 on Jeep
Electronic Frontal Sensor 2 Malfunction
B0101 on Jeep vehicles indicates electronic frontal sensor 2 malfunction. Au7o has documented this code across 1 Jeep model — most commonly on Grand Wagoneer. 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.
Common Causes of B0101
- •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
B0101 on Jeep by Model
Jeep Grand Wagoneer(1 issue)
- Airbag System Failure - ORC Module & B-Pillar Trim (Multiple Recalls)2022-2023
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.
