B1430 — Seat Belt Switch Circuit Short To Ground

About B1430

B1430 is a manufacturer-specific body diagnostic trouble code. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B1430 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.

B1430 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The Body Control Module (BCM) or Occupant Restraint Controller (ORC) monitors the seat belt buckle switch through an input circuit with an internal pull up reference voltage. The buckle switch is a contact inside the seat belt receiver that closes a path to ground when the latch is fastened, signalling buckle state to the module. DTC B1430 sets when the module detects the seat belt switch input pulled to ground continuously, even when the buckle should be open and the input should sit at the pull up reference. Common causes include chafed wiring under the seat, water intrusion at the buckle co...
