Code Definition

B1650 — Seat Driver Recline Forward Circuit Short To Ground

System: Body  |  Type: Manufacturer-Specific  |  Make: Ford

About B1650

B1650 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 B1650 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.

B1650 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 B1650 fault code indicates that the Driver Seat Module (DSM) or Body Control Module (BCM) has detected a short to ground on the driver seat recline forward control circuit. This circuit drives the electric motor that tilts the seat backrest forward when the driver operates the recline switch on power adjustable seats. The seat module energises the recline forward output and watches the line voltage and current draw, setting B1650 when it sees the output pulled to ground unexpectedly or sees a sustained excessive current that indicates a low impedance path to chassis.
