About C1451

C1451 is a manufacturer-specific chassis diagnostic trouble code. It belongs to the C-prefix family of codes, which covers chassis, braking, steering, suspension, or stability-control faults.

When C1451 is stored, the module has detected an open (broken or disconnected) electrical path 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.

C1451 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 C1451 fault code indicates the ABS or traction control module has detected an open circuit on the traction control pump motor circuit. The pump motor is used to pressurise the brake hydraulic system during ABS, traction control, and stability control interventions. This code is specifically set when the module commands the motor to run but no current flow is detected, indicating either an open winding inside the motor, an open in the supply wiring, or worn motor brushes that have lost contact with the commutator. When this code is active, ABS, traction control, and stability control are ty...
