About B0130

B0130 is a generic (obd-ii standard) body diagnostic trouble code recorded for Toyota vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B0130 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) 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 B0130 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 airbag control module, called the Center Airbag Sensor Assembly or SRS ECU on Toyota, continuously monitors the right hand front seat belt pretensioner squib circuit for correct resistance and bias voltage. DTC B0130 sub code 63 sets when the module detects a shorted condition in that firing circuit, either the two squib wires shorted together, a squib wire shorted to chassis ground, or a squib wire shorted to a power feed. The pretensioner is a pyrotechnic device in the seat belt buckle or retractor that fires to pull slack out of the belt during a collision, and its squib is the small re...
