About B1963

B1963 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 B1963 is stored, the module has detected an open (broken or disconnected) electrical path 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.

B1963 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.

The potentiometer is mounted on the seat slide track and reports the fore and aft position of the seat to the module for memory recall and soft stop control at the slide limits. An open in the supply, signal, or ground leg of the potentiometer leaves the module without a usable position reference for the slide axis and is logged as B1963. With this code active, seat memory recall for fore and aft position is disabled and...
