Traction Control System (TCS) Operation

2005 Hyundai Elantra GLS, 4D Hatchback, AutomaticSECTION Traction Control System (TCS) Operation
  1. NORMAL MODE
    DIAGNOSIS PROCEDURE

    Solenoid valve State Valve Motor pump TC valve
    IN (NO) OFF OPEN OFF OFF
    OUT (NC) OFF CLOSE
    • In the normal driving condition, TC valve (normally open) is the passage between the master cylinder and the each wheel cylinder.
    • When brake pedal is applied, brake pressure is delivered to the wheel cylinders via NO-TC valve and all solenoid valves inside the hydraulic unit are deactivated.
    • In case of TCS malfunction it does not affect brake operation.
  2. PRESSURE INCREASE MODE
    DIAGNOSIS PROCEDURE

    Solenoid valve State Valve Motor pump TC valve
    IN (NO) FRONT: OFF
    REAR: ON    		 FRONT: OPEN
    REAR: CLOSE    		 ON ON
    OUT (NC) OFF CLOSE
    • If a front wheel spin is detected, TCS begins a brake control to decrease a wheel spin.
    • Hydraulic shuttle valve (HSV) is opened.

      Brake fluid is supplied from the master cylinder by motor operation to the spin wheel via HSV.

    • TC valve is closed (ON).

      Brake pressure generated from motor pump is delivered only to the front wheel.

    • Inlet valve remains open to deliver the brake pressure generated from motor pump to the spinning wheels.
  3. PRESSURE DUMP MODE
    DIAGNOSIS PROCEDURE

    Solenoid valve State Valve Motor pump TC valve
    IN (NO) ON CLOSE ON ON
    OUT (NC) FRONT: ON
    REAR: OFF    		 FRONT: OPEN
    REAR: CLOSE
    • When the wheel deceleration is under the threshold and the wheel spin is reduced under a slip threshold, applied brake pressure is reduced to get a optimum traction force.
    • Outlet valve is open to release the brake pressure and inlet valve is closed to block the pressure increase from the motor pump.
    • Hydraulic shuttle valve (HSV) remains opened, TC valve is ON.
    • Motor is ON, to dump the brake fluid being released from the lock-up wheel.
  4. PRESSURE HOLD MODE
    DIAGNOSIS PROCEDURE

    Solenoid valve State Valve Motor pump TC valve
    IN (NO) ON CLOSE ON ON
    OUT (NC) OFF CLOSE

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
