B1541 — Mirror Driver Switch Assembly Circuit Short To Battery

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

About B1541

B1541 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 B1541 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.

B1541 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

This code relates to the Mirror Driver Switch Assembly circuit, the electric mirror control switch in the driver door trim panel that selects either side mirror and supplies the directional power and ground signals to the chosen mirror motor. The Body Control Module (BCM), or in some applications the Driver Door Module, monitors the switch input lines for over voltage conditions and sets B1541 specifically when one of the monitored circuits is shorted to battery voltage. A short to battery means an unintended 12V supply has bridged into a circuit that should only see voltage when the switch is...
