B1653 — Seat Driver Recline Backward Circuit Short To Battery

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

About B1653

B1653 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 B1653 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.

B1653 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 B1653 fault code indicates that the Driver Seat Module (DSM) or Body Control Module (BCM) has detected a short to battery voltage on the driver seat recline backward control circuit. This circuit drives the electric motor that tilts the seat backrest rearward when the driver operates the recline switch. The seat module monitors the recline backward output line for unexpected voltage, and when it sees battery positive on the line while the output is commanded off, or sees a higher than expected voltage during the active cycle, it sets B1653. With this code present the recline backward funct...
