About C1273

C1273 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 C1273 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.

C1273 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

On systems with dual hydraulic pump motors, the Anti-lock Brake System (ABS) module monitors each pump through an independent feedback input. DTC C1273 is set when the ABS module detects that the number two motor feedback circuit is shorted to battery voltage, meaning the input that should report motor state is being held high externally regardless of motor activity. This is typically caused by harness damage where the feedback wire has contacted a powered conductor, by welded relay contacts back feeding voltage into the monitor circuit, or by an internal module input failure. ABS, traction, a...
