About B0083

B0083 is a generic (obd-ii standard) body diagnostic trouble code. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B0083 is stored, the module has detected a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: Body (B) codes are often stored in the body control module, airbag module, or climate module. A basic OBD-II tool usually will not read body codes — an enhanced or OEM-level scan tool is typically required.

Because B0083 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

This code is triggered by the Supplemental Restraint System (SRS) control module when it detects a fault in the left side impact sensor 1 circuit, a sensor typically located on the B pillar or door area. The control module continuously monitors the sensor signal and reference circuits for correct voltage levels so that side impact data is available. The DTC sets if an open circuit, short to ground, short to voltage, or an abnormal signal is detected, indicating compromised sensor communication or function. When this code is stored the airbag warning lamp illuminates and side airbag or curtain ...
