Code Definition

C1214 — ABS Inlet Valve Coil RF Circuit Failure

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

About C1214

C1214 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 C1214 is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

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.

C1214 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 Anti-lock Brake System (ABS) module operates inlet (apply) and outlet (dump) solenoid valves within the Hydraulic Control Unit (HCU) to modulate brake pressure at each wheel during ABS, traction control, and stability control events. DTC C1214 sets when the ABS module detects a generic electrical failure on the right front inlet valve coil control circuit, which can include an open circuit, a short to voltage, a short to ground, or a current draw that falls outside the expected range when the valve is energised. The right front inlet valve admits master cylinder pressure into the RF calipe...
