Code Definition

B112F (87) — Emergency Brake Lamp Circuit Malfunction

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

About B112F

B112F 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 B112F 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.

B112F 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) energises and monitors the emergency brake (parking brake) warning lamp circuit in the instrument cluster, driving the lamp when the parking brake is applied and sensing the return current to confirm the lamp and wiring are intact. DTC B112F:87 is set when the BCM detects an abnormal condition on this circuit, such as an open circuit with no current flow, a short to ground or battery with excessive current, or resistance outside the expected range, persisting beyond the defined threshold during parking brake operation. The circuit typically includes a lamp driver ...
