About B2302

B2302 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 B2302 is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

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 B2302 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

The Seat Module or Body Control Module monitors the powered headrest position through a feedback potentiometer attached to the headrest adjustment mechanism. DTC B2302 sets when the module detects that the headrest potentiometer signal is open, shorted to ground, shorted to voltage, or stuck outside the normal operating range expected during headrest motor commands. The potentiometer provides a continuous voltage signal proportional to headrest height, allowing the module to know where the headrest is and to stop motors at memorized recall positions. When this code is set, the powered headrest...
