B1724 — Seat Driver Rearward Switch Circuit Short To Ground

About B1724

B1724 is a manufacturer-specific body diagnostic trouble code recorded for Ford vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B1724 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.

B1724 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 Driver Seat Module (DSM) monitors the driver seat rearward switch input circuit and sets code B1724 when the switch signal line is detected pulled to ground continuously when no switch input is expected. A short to ground typically results from chafed insulation allowing the switch wire to contact a metal seat frame component or chassis ground, a stuck switch holding the input low, or moisture creating a low resistance path between the signal and ground. The driver seat rearward switch is a normally open momentary contact device on the seat side trim that signa...
