DESCRIPTION

The linear solenoids SLA and SLR control the regulator based on signals from the No. 1 skid control ECU (brake booster with master cylinder assembly) and produce servo pressure in accordance with the vehicle condition.

When the system is normal, the switching solenoid SGH is opened to allow brake fluid to flow to the stroke simulator when the brake pedal is depressed. When the system is abnormal, the switching solenoid SGH closes to prevent the flow of brake fluid.

When the system is normal, the switching solenoid SSA is closed. When the system is abnormal, the switching solenoid SSA is opened to allow fluid to flow to the brake fluid level warning switch (brake booster with master cylinder assembly).

HINT:

  • If the supply voltage decreases, a drop in current may cause DTCs to be stored.
  • Brake pressure control solenoid "C": Solenoid SLA.
  • Brake pressure control solenoid "D": Solenoid SLR.
  • Brake pressure control solenoid "E": Solenoid SSA.
  • Brake pressure control solenoid "F": Solenoid SGH.

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. Depress the brake pedal 1 or more times. [*]

    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/EPB / 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.

CAUTION / NOTICE / HINT

NOTICE:

After replacing the No. 1 skid control ECU (brake booster with master cylinder assembly), perform "Calibration" after performing "Reset Memory".
