About B1750

B1750 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 B1750 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.

B1750 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) on Ford vehicles equipped with passive anti-theft and shift interlock systems monitors the Park/Neutral Position (PNP) switch input to confirm transmission selector position. DTC B1750 is set when the BCM detects an open circuit on the PNP switch input, meaning the signal path between the switch and the module shows no continuity in any selector position. The PNP switch is typically a multi tap rotary switch on the transmission case or shifter assembly that should provide a defined value to the BCM for each gear, so an open circuit results in the module seeing no ...
