Brake/EPB

  • SAE Code: C117C
  • Output ECU: skid control ECU (brake actuator assembly)

C117D00

Driver Demand Brake Pressure Sensor "A" for Force Blending Signal Malfunction

The electric brake booster (brake booster with master cylinder assembly) receives a malfunction of master cylinder pressure sensor inside skid control ECU (brake actuator assembly).

Skid control ECU (brake actuator assembly)

Comes on

Brake/EPB

  • SAE Code: C117D
  • Output ECU: skid control ECU (brake actuator assembly)

MONITOR DESCRIPTION

C117C:
  • When a certain amount of time has elapsed after the ignition switch is turned to ON, the power supply voltage of the electric brake booster (brake booster with master cylinder assembly) is a certain value or more, and the target master cylinder pressure with calibration force applied to the brake pedal is outside of a certain range, the electric brake booster (brake booster with master cylinder assembly) illuminates the MIL and stores this DTC.
C117D:
  • After the ignition switch is ON for a certain amount of time, the power supply voltage of the electric brake booster (brake booster with master cylinder assembly) is a certain value or more, and the virtual master cylinder pressure when the VSC is operating is outside of a certain range, the electric brake booster (brake booster with master cylinder assembly) illuminates the MIL and stores this DTC.

CONFIRMATION DRIVING PATTERN

NOTICE:

When performing the normal judgment procedure, make sure that the driver door is closed and is not opened at any time during the procedure.

HINT:

  • After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
  • When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
  1. Connect the GTS to the DLC3.
  2. Turn the ignition switch to ON and turn the GTS on.
  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  4. Turn the ignition switch off.
  5. Turn the ignition switch to ON (READY) and turn the GTS on.
  6. Wait for 2 seconds or more. [*]

    HINT:

    [*]: Normal judgment procedure.

    The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.

  7. Enter the following menus: Chassis / Brake Booster / Utility / All Readiness.
  8. Check the DTC judgment result.

    HINT:

    • If the judgment result shows NORMAL, the system is normal.
    • If the judgment result shows ABNORMAL, the system has a malfunction.
    • If the judgment result shows INCOMPLETE, perform driving pattern again.

PROCEDURE
