About B2582

B2582 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 B2582 is stored, the module has detected an open (broken or disconnected) electrical path in the monitored circuit.

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 B2582 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 Passenger Occupant Detection System uses a sensor or weight sensing mat in the passenger seat cushion to determine whether the seat is occupied and, on classification systems, identify the occupant size to enable or suppress the front passenger airbag during a crash event. DTC B2582 sets when the Occupant Detection Module or Restraints Control Module detects that the passenger occupant detection signal circuit is open, with no continuity between the module and the sensor. The system applies a reference voltage to the sensor circuit and monitors current flow, an open circuit prevents the ex...
