Causes

  • Defective inlet or outlet solenoid valve (stuck, shorted or open coil)
  • Wiring problems: open, short to ground, short to battery, or intermittent connection
  • Corroded or loose connector at the hydraulic unit or ABS/ESC module
  • Contaminated brake fluid or debris preventing valve movement
  • Failed hydraulic control unit (pump/driver) or internal driver electronics
  • Blown fuse or related power supply/ground issue

Symptoms

  • ABS/ESC warning lamp or traction control lamp illuminated
  • Reduced or altered braking/traction control performance
  • Diagnostic trouble code present (C2114) and possibly related ABS codes
  • Possible unusual brake pedal feel or noise from hydraulic unit
  • Driveability/traction intervention limitations (limp mode depending on vehicle)

What to check

  • Scan ABS/ESC module for stored/active codes and freeze frame data
  • Visual inspection of ABS hydraulic unit connectors and wiring harness for damage or corrosion
  • Backprobe solenoid connector with ignition ON to check supply and ground
  • Measure coil resistance with multimeter (compare to service data) and inspect for open/short
  • Check for proper supply voltage (key ON) at valve connector
  • Inspect brake fluid level and condition; check for contamination or metallic particles

Signal parameters

  • Command signal: PWM duty cycle from ABS/ESC module (0–100% depending on commanded valve action)
  • Supply voltage at connector: nominal battery voltage (~11–14 V with engine running) when powered
  • Ground: low ohms to chassis when driver commanded
  • Valve coil resistance: low-ohm coil (typically a few ohms to tens of ohms — check vehicle service data)
  • Activation response: valve should change state when commanded in actuator test; current draw increases during activation (use service manual values)

Diagnostic algorithm

  1. Read and record all stored ABS/ESC codes and freeze frame data. Note any other related codes.
  2. Clear codes and attempt to reproduce. See if C2114 returns and whether it is intermittent or permanent.
  3. Visually inspect connectors and wiring to the hydraulic unit and ABS module for corrosion, pin damage, or poor mating. Repair as needed.
  4. Backprobe the valve connector while performing an actuator test: verify supply voltage, command PWM, and ground continuity. Compare signals to service specifications.
  5. With ignition OFF, measure valve coil resistance. If open or shorted relative to spec, replace the valve.
  6. If electrical signals are correct and coil resistance is within spec, perform a functional/bench test of the valve or substitute a known-good valve if available.
  7. Inspect brake fluid for contamination and flush system if contaminated. Remove debris from hydraulic unit if accessible and recommended by manufacturer.
  8. If valves and wiring check good, suspect internal ABS hydraulic control unit driver failure. Verify module communications and power/ground circuits. Replace or rebuild hydraulic control unit only after confirming external components are good.
  9. After repairs, clear codes and perform road/test drive and actuator tests to confirm the repair. Monitor for reoccurrence.

Likely causes

  • Corroded/loose connector or damaged wiring to the valve
  • Valve coil stuck or electrically failed
  • Contamination/debris in hydraulic unit preventing valve travel
