About C1275

C1275 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 C1275 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.

C1275 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 Control Module monitors the integrity of the solenoid relay circuit by checking the feedback voltage on the monitor pin during self test. DTC C1275 sets when the module detects battery voltage present on the relay output or feedback circuit when the relay should be off, indicating an unwanted short to the battery positive supply. The solenoid relay supplies switched battery voltage to the ABS valve solenoid coils inside the hydraulic control unit, and is only commanded closed when the module is ready for an ABS or stability control event. When this code is active the ABS warning lamp i...
