1 vehicles · 1 makes · $300-$1,500 repair
Most Reported On
B0083 is an OBD-II diagnostic trouble code meaning “Left Front Impact Sensor Circuit.” 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. This code is most commonly reported on 2013-2019 Cadillac XTS (Luxury, Premium, Platinum, V-Sport, Vsport), with repair costs ranging from $300 to $1,500.

Diagnostic Tools
This is a body code. A basic engine-code reader will not show it — you need a scanner that reads body modules. These read B0083.
One caveat that applies to every scanner: only powertrain codes are standardised across manufacturers. Body, chassis and network coverage is "enhanced" diagnostics, and how deep it goes varies by make and model year — check your specific vehicle against the tool's coverage list before buying.

What you can do yourself, and what needs a shop
Reading the code, clearing it, and watching whether it returns is a driveway job with the right scanner. These steps are not:
- Module programming or software updates — needs the manufacturer software or a J2534 pass-through with a paid subscription.
- Replacing a control module — most are VIN-programmed and immobilizer-registered, so a new one does nothing until it is coded to your car.
- Airbag/SRS component work — a stored fault can deploy a live device.
If the vehicle is still under warranty, check for an open recall or technical service bulletin before buying anything — the repair may already be covered.
