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

About B1683

B1683 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 B1683 is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

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.

B1683 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

B1683 is a Ford specific code indicating a circuit failure in the driver or passenger door mirror selector switch circuit. The mirror switch is a multi position resistor ladder type switch built into the master driver door panel that allows the driver to select between the left and right exterior mirrors before adjusting position with the joystick. The Body Control Module (BCM) reads the switch position via a single analog input and expects a specific voltage range for each position. This code sets when the BCM detects an out of range voltage, an open circuit, or a short condition on the switc...
