B0100 on Jeep
Electronic Frontal Sensor 1 Malfunction
B0100 on Jeep vehicles indicates electronic frontal sensor 1 malfunction. Au7o has documented this code across 1 Jeep model — most commonly on Grand Wagoneer. This is a body code in the airbag (SRS) system indicating a malfunction with electronic frontal impact sensor 1, one of the crash sensors that detects a frontal collision and tells the airbag controller when to deploy. The system runs a self-check on these sensors and their wiring, and when sensor 1 fails to communicate properly, reads out of range, or shows a circuit fault, this code sets and usually lights the airbag warning lamp. Because it affects crash protection, the airbags or seatbelt pretensioners may not deploy as designed until it's fixed. It generally points to a faulty sensor, its wiring/connector, or the airbag control module.
Common Causes of B0100
- •Faulty frontal impact (crash) sensor
- •Damaged, open, or shorted sensor wiring
- •Corroded or unseated sensor connector
- •Connector damage from a prior collision or repair
- •Poor ground or power supply to the sensor
- •Faulty airbag (SRS) control module

- 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.
