About C1401

C1401 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 C1401 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.

C1401 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 C1401 fault code indicates the ABS or traction control module has detected an open circuit on the right front (RF) traction control valve. The traction control valves are solenoid actuated valves inside the ABS hydraulic control unit that the module energizes to apply or release brake pressure at individual wheels during traction control and stability control interventions. This code is specifically set when the right front valve coil fails to conduct current when commanded, indicating either an open winding inside the valve coil or an open circuit somewhere in the wiring between the modul...
