ELECTRIC PARKING BRAKE SYSTEM INITIALIZATION


  1. Note

    If the parking brake ECU assembly or parking brake with bracket actuator assembly is replaced, perform the "Reset Memory" and "Acquire Tension Sensor Zero Point" procedures.

    RESET MEMORY AND ACQUIRE TENSION SENSOR ZERO POINT (with GTS)


    1. Turn the engine switch off.

    2. Connect the GTS to the DLC3.

    3. Turn the engine switch on (IG) and the GTS on.

    4. Enter the following menus: Chassis / Electric Parking Brake / Utility / Reset Memory.

    5. Follow the GTS display and perform reset memory.


      Chassis > Electric Parking Brake > Utility
      Tester Display
      Reset Memory

      Tech Tips

      When the reset memory is completed, the parking brake indicator light (red) will blink at 1 second intervals (0.5 seconds on and 0.5 seconds off).

    6. Perform the release control. Check that the parking brake indicator light (red) turns off.

      Tech Tips

      This procedure acquires the tension sensor zero point.

  2. RESET MEMORY AND ACQUIRE TENSION SENSOR ZERO POINT (without GTS)

    Note

    If the parking brake ECU assembly or parking brake with bracket actuator assembly is replaced, perform the "Reset Memory" and "Acquire Tension Sensor Zero Point" procedures.


    1. Turn the engine switch off.

    2. B000TSLE25

      Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3.

      SST
      09843-18040

      Note

      Do not connect the wrong terminals, as this will cause parts to be damaged.

    3. Turn the engine switch on (IG).

      Tech Tips

      The parking brake indicator light (red) will blink at 0.25 second intervals (0.125 seconds on and 0.125 seconds off).

    4. Perform both of the following procedures within 8 seconds:


      1. Perform the following with the electric parking brake switch twice: lock condition → off → release condition → off.

      2. Perform the following with the brake pedal: depress → release → depress → release.

        B000WCTC02
        *1 Lock Switch *2 Release Switch
        *3 Brake Pedal - -
        *a ON *b OFF
        *c Within 8 sec. - -

        Note

        If the operation is performed too quickly, the system may not respond. If the system does not respond, perform the operation again at a slower speed.

    5. With the engine switch on (IG), disconnect the connection of terminals 13 (TC) and 4 (CG) of the DLC3.

    6. Check that the parking brake indicator light (red) blinks at 1 second intervals (0.5 seconds on and 0.5 seconds off).

      Note

      If terminal 13 (TC) and 4 (CG) of the DLC3 are not disconnected, the blinking pattern (1 second intervals (0.5 seconds on and 0.5 seconds off)) cannot be checked.

      Tech Tips

      If the parking brake indicator light (red) blinking pattern (1 second intervals (0.5 seconds on and 0.5 seconds off)) is confirmed, the clear procedure is completed. If not confirmed, repeat the procedures above.

    7. Perform the release control. Check that the parking brake indicator light (red) turns off.

      Tech Tips

      This procedure acquires the tension sensor zero point.

  3. PARKING BRAKE BEDDING

    CAUTION:


    • B000UB5C01
      *a Condition without performing brake bedding

      Do not operate the parking brake without first performing brake bedding of the parking brake shoe and rear disc.

    • Performing bedding creates the basic braking force of the parking brake, so without it the parking brake will not provide sufficient braking performance, which may result in a serious accident.

    Note

    If one of the following is performed, perform parking brake bedding.


    • Rear disc is replaced or removed and installed.

    • Parking brake shoe is replaced or removed and installed.

    • Parking brake with bracket actuator assembly is replaced or removed and installed.


    1. Turn the engine switch on (IG).

    2. Cancel the AUTO function (shift-linked function).

    3. Change the shift state to P.

    4. Release the parking brake.

    5. Turn the engine switch off.

    6. Connect the GTS to the DLC3.

    7. Turn the engine switch on (IG) and the GTS on.

    8. Enter the following menus: Chassis / Electric Parking Brake / Utility / Check Mode.


      Chassis > Electric Parking Brake > Utility
      Tester Display
      Check Mode

    9. Follow the GTS display and select "Next".

    10. Check that test mode is entered.

      Tech Tips

      The parking brake indicator light (red) will blink at 0.25 second intervals (0.125 seconds on and 0.125 seconds off).

    11. Perform parking brake bedding.


      1. Drive the vehicle at 30 km/h (19 mph).

      2. Push the parking brake switch to the lock side for 5 seconds.

        Note

        The braking power is generated from the parking brake while driving the vehicle. This will cause the vehicle speed to decrease. Depress the acceleration pedal to maintain the speed at 30 km/h (19 mph).

        Tech Tips


        • While the switch is pushed, the parking brake indicator light (red) stops blinking at 0.25 second intervals (0.125 seconds on and 0.125 seconds off) and illuminates steadily.

        • During this operation, the tension is automatically adjusted.

      3. After 5 seconds, check that the parking brake indicator light (red) turn off.

        Tech Tips

        The brake force decreases.

      4. Release the electric parking brake switch assembly.

      5. Stop the vehicle.

      6. Turn the engine switch off.
