B1723 — Seat Driver Rearward Switch Circuit Short To Battery

About B1723

B1723 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 B1723 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.

B1723 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 B1723 when the switch signal line is detected at battery voltage when it should be at ground or reference voltage. A short to battery condition typically results from chafed insulation allowing the switch wire to contact a B+ feed, a stuck switch holding the line high, or an internal fault that pulls the input rail up to battery voltage. The driver seat rearward switch is a normally open momentary contact device on the seat side trim that signals the seat module to dri...
