B1614 — Wiper Rear Mode Select Switch Circuit Short To Ground

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

About B1614

B1614 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 B1614 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.

B1614 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 B1614 code is set by the Generic Electronic Module (GEM) on Ford vehicles when the rear wiper mode select switch input wiring is shorted to ground. The GEM applies a reference voltage to the switch circuit and watches the return signal to determine which rear wiper mode the driver has selected, so a hard short to chassis pulls the input below the lowest valid threshold and triggers this code. The fault is most often caused by chafed insulation that allows the signal wire to touch a metal panel or an internally shorted switch. When this code is set, the rear wiper may run in a default mode,...
