C1112 — ABS Power Relay Coil Short Circuit To Ground

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

About C1112

C1112 is a manufacturer-specific chassis diagnostic trouble code recorded for Ford vehicles. It belongs to the C-prefix family of codes, which covers chassis, braking, steering, suspension, or stability-control faults.

When C1112 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit.

Scanning & clearing: Chassis (C) codes are stored in the ABS, traction control, or stability-control modules. An enhanced or OEM-level scan tool is usually required to read and clear them.

C1112 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 ABS Power Relay supplies battery voltage to the ABS hydraulic unit, including the pump motor and solenoid valves, with its coil energised by the ABS module. DTC C1112 indicates the module has detected a short to ground on the relay coil control circuit, meaning the control wire is grounded outside of normal switching. Depending on the circuit design this can cause the relay to remain energised or can be flagged by the module monitoring the driver. When this code is present the ABS and traction control functions are disabled and the warning lamps illuminate, while normal hydraulic braking r...
