C1402 — Traction Control Valve RF Circuit Short To Ground

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

About C1402

C1402 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 C1402 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.

C1402 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 C1402 fault code indicates the ABS or traction control module has detected a short to ground on the right front (RF) traction control valve circuit. The traction control valves are solenoid actuated valves inside the ABS hydraulic control unit used during traction control and stability control interventions to apply or release brake pressure at individual wheels. This code is specifically set when the module detects excessive current flow indicating the valve coil control wire is shorted directly to chassis ground, either through a damaged wire, a shorted valve coil winding, or a faulty in...
