B1719 — Seat Driver Forward Switch Circuit Short To Battery

About B1719

B1719 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 B1719 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.

B1719 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 forward switch input circuit and sets code B1719 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 seat forward switch is a normally open momentary contact device on the seat side trim that signals the seat module to drive the ho...
