CLUTCH SYSTEM(for 1WW, 2WW) CALIBRATION


  1. INSPECT DRIVE AWAY RELEASE FUNCTION


    1. Before removing the clutch release with bearing cylinder assembly, brake pedal stroke sensor (clutch pedal stroke sensor), clutch master cylinder assembly, or clutch pedal sub-assembly, check the operation of the drive away release function of the electric parking brake.

      Tech Tips


      • Perform the inspection on as level a surface as possible.

      • Check the current behavior of the vehicle when accelerating from rest.

      • Check the timing of the electric parking brake release.


      1. Accelerate the vehicle after operating the electric parking brake, and then check when the electric parking brake is released. (*1)

      2. Accelerate the vehicle slightly more rapidly than in step *1 after operating the electric parking brake, and then check when the electric parking brake is released.

  2. PERFORM CLUTCH ENGAGEMENT POINT LEARNING

    Note

    Under the following conditions, it is necessary to perform clutch engagement point learning.


    • When replacing or removing/installing the clutch cover assembly.

    • When replacing or removing/installing the clutch disc assembly.

    • When replacing the clutch release with bearing cylinder assembly.

    • When replacing or removing/installing the brake pedal stroke sensor (Clutch pedal stroke sensor).

    • When replacing or removing/installing the clutch pedal sub-assembly.

    • When replacing or removing/installing the clutch master cylinder assembly.


    1. Warm up the engine.

    2. While driving the vehicle at a speed of 50 km/h (37 mph/h) or more, downshift from 4th to 3rd gear and check that the engine speed increases. (*1)

      Note

      Do not operate the accelerator pedal at this time.

    3. Perform step *1 five times.

    4. Accelerate the vehicle after operating the electric parking brake, and then check when the electric parking brake is released. (*2)

      Note

      Make sure that there is no sticking or abnormal feeling due to a delayed release of the electric parking brake.

      Tech Tips

      Check that the vehicle behaves in approximately the same fashion as it did when the vehicle behavior upon acceleration from rest was checked before performing this step.

    5. Accelerate the vehicle slightly more rapidly than in step*2 after operating the electric parking brake and then check the time it takes for the electric parking brake to be released. (*3)

      Note

      Make sure that there is no sticking or abnormal feeling due to a delayed release of the electric parking brake.

      Tech Tips

      Check that the vehicle behaves in approximately the same fashion as it did when the vehicle behavior upon acceleration from rest was checked before performing this step.

    6. If there is any abnormal feeling, repeat step *1 twenty times.

    7. Perform steps *2 and *3.
