B10A1 — Passenger Power Mirror Fold Outward Circuit Short to Ground

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

About B10A1

B10A1 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 B10A1 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.

B10A1 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) controls the passenger power mirror fold function by switching a dedicated output circuit to the fold motor inside the mirror assembly. DTC B10A1 is set when the BCM detects that the fold outward control circuit is pulled to ground during a commanded fold out event or during a circuit integrity self test, which indicates an unintended short to ground in the wiring or mirror assembly. The fold outward motor is a small DC motor that physically unfolds the mirror from its stored position, typically commanded when the ignition is switched on or when the mirror fold bu...
