Code Definition

C1449 — Traction Control Motor Coherency Fault

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

About C1449

C1449 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.

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.

C1449 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 C1449 fault code indicates the ABS or traction control module has detected a coherency fault on the traction control pump motor circuit. The traction control pump motor (also called the ABS pump motor or hydraulic pump) is used to pressurise the brake hydraulic system during ABS, traction control, and stability control interventions. The module monitors motor activation by comparing the commanded state against feedback from the motor relay or current sensing circuit. This code is set when the module detects the motor responding inconsistently with its commands, such as the motor running wh...
