C1115 — ABS Power Relay Output Short Circuit To Battery

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

About C1115

C1115 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 C1115 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.

C1115 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 output circuit delivers switched battery voltage from the relay contacts to the ABS hydraulic unit, supplying the pump motor and solenoid valves. DTC C1115 indicates the module has detected battery voltage on the relay output circuit when the relay should be open, pointing to a short to a power feed or relay contacts that are stuck closed. With voltage present on the output when it should not be, the module flags the fault to protect the hydraulic unit. When this code is present the ABS and traction control functions are disabled and the warning lamps illuminate, while norm...
