BRAKE MASTER CYLINDER (for LHD) ON-VEHICLE INSPECTION

Note

A DTC may be stored during the inspection procedure. Be sure to clear the DTC and check that a normal system code is output after the inspection is finished.


  1. CHECK BRAKE MASTER CYLINDER


    1. Check battery voltage.

      Standard voltage
      11 to 14 V (while the power switch is off)

    2. Connect the intelligent tester and set a pedal effort gauge.


      1. Set a pedal effort gauge.

      2. Move the shift lever to P and apply the parking brake.

      3. Connect the intelligent tester to the DLC3.

      4. Turn the power switch on (IG) and turn the intelligent tester on.

      5. Clear the DTCs Click here.

    3. Check operation without the brake booster.


      1. Inspect and adjust the brake pedal Click here.

      2. To prohibit the brake control, enter the following menus: Chassis / ABS/VSC/TRC / Utility / Electronically Controlled Brake system Utility / ECB (Electronically Controlled Brake system) Invalid.

      3. Enter the following menus: Chassis / ABS/VSC/TRC / Data List "Master Cylinder Sensor", "Master Cylinder Sensor 2", "Stroke Sensor" and "Stroke Sensor 2".

      4. Check the value output from "Master Cylinder Sensor", "Master Cylinder Sensor 2", "Stroke Sensor" and "Stroke Sensor 2" by depressing the brake pedal.
