B0083 on Cadillac
Left Front Impact Sensor Circuit
B0083 on Cadillac vehicles indicates left front impact sensor circuit. Au7o has documented this code across 1 Cadillac model — most commonly on XTS. Manufacturer-specific airbag/restraint code, most commonly seen on GM vehicles (Chevrolet, GMC, Buick, Cadillac, and Opel/Vauxhall), where the Sensing and Diagnostic Module (SDM) reports a fault in the left front impact sensor circuit. Note that the broader SAE/ISO listing also assigns B0083 to a second-row seat belt load limiter deployment control circuit on some applications, so confirm against your vehicle's service information. When this code sets, the airbag warning light comes on and the restraint system may disable itself, meaning airbags and pretensioners may not deploy in a crash. The sub-code (symptom byte, for example B0083-39 internal failure or -05 open circuit) matters here and should be read before replacing anything. Typical repair costs on Cadillac range from $300 to $1,500, depending on the specific model and root cause.
Common Causes of B0083
- •Failed left front impact sensor, or a sensor of the wrong part number for the vehicle's build
- •Damaged wiring or connector at the impact sensor, often from front-end collision damage or corrosion
- •Loose sensor mounting bolt or poor ground at the sensor mount
- •Water intrusion into the sensor connector
- •SDM (airbag control module) internal fault
B0083 on Cadillac by Model
Cadillac XTS(1 issue)
- Passenger Presence System Fault / Passenger Airbag Light On2013-2019
The front passenger seat contains a Passenger Presence System (occupant-classification sensor/module and wiring harness) that tells the airbag controller whether to enable the passenger airbag. On the XTS the sensor mat, the under-seat connector, and the wiring harness are prone to faults, illuminating the SRS/'Service Air Bag' warning and often leaving the PASSENGER AIRBAG OFF indicator stuck on (or incorrectly on with an adult seated). Because a fault can disable passenger airbag deployment, this is a genuine safety concern.
