B0100 on Chevrolet
Electronic Frontal Sensor 1 Malfunction
B0100 on Chevrolet vehicles indicates electronic frontal sensor 1 malfunction. Au7o has documented this code across 2 Chevrolet models — most commonly on Camaro, Impala. 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
B0100 on Chevrolet by Model
Chevrolet Camaro(1 issue)
- Driver Airbag Emblem Separation Hazard2017-2021
The plastic 'Camaro' emblem located on the steering wheel airbag cover may separate during frontal airbag deployment. In a crash, plastic emblem pieces can become projectiles, increasing risk of injury to the driver.
Chevrolet Impala(1 issue)
- Ignition Switch Failure and Recall (NHTSA 14V-394)2003-2006
The 2003-2006 Impala was included in the massive GM ignition switch recall affecting millions of vehicles. The ignition switch has a weak detent spring that allows the key to slip from the "Run" position to the "Accessory" or "Off" position while driving. When this happens, the engine shuts off, the power steering and brake boost are lost, and the airbags are disabled — all without warning. The issue is exacerbated by heavy key chains that add weight and leverage on the ignition cylinder. This defect was linked to numerous fatalities.
