C0014 Right Front Inlet Control

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modePossible

Covers the right front inlet (apply) solenoid valve of the ABS hydraulic modulator, the mirror of C0010 on the right front corner. The module closes this valve to isolate the right front brake circuit and hold wheel pressure during ABS, traction or stability control, then opens it to reapply pressure from the master cylinder or pump. It monitors the coil for opens, shorts to supply or ground and resistance outside the calibrated window. A confirmed electrical fault disables ABS and the stability functions and turns on the ABS warning lamp, with conventional foundation braking unaffected. No manufacturer documents this code publicly; NHTSA's safety study of hydraulic ABS/ESC brakes describes the hold valve used per wheel, and a pump patent shows it as a normally open apply valve.

Likely causes

Inlet valve coil open or shorted
Harness or connector corrosion
Internal hydraulic modulator fault

Symptoms

  • ABS warning lamp on
  • ABS and stability control disabled
  • Normal braking retained
