About C1452

C1452 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 C1452 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.

C1452 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 C1452 fault code indicates the ABS or traction control module has detected a short to battery voltage 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 detects battery voltage on the motor control circuit when the motor should not be commanded on, indicating the control wire is shorted to a battery feed or the motor relay contacts are welded closed. When this code is active, ABS, traction control, and stability control ar...
