About B00D2

B00D2 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 B00D2 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 B00D2 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 Supplemental Restraint System (SRS) warning lamp is a driver notification output that the airbag control module (ACM) commands during the bulb check at key on and whenever an SRS fault is stored. The ACM drives the lamp, which is normally located in the instrument cluster, either directly through a low side driver or by a serial data message to the cluster, and it monitors the circuit for the correct electrical response. DTC B00D2 sets when the ACM determines that the warning lamp circuit is not behaving as expected, for example the lamp fails to illuminate when commanded, stays on when it...
