    Default CVT Start Clutch Calibration - The AUTEL Way

    ALHAMDULILLAH

    I had been looking for a bi-directional scan tool since long and been saving up for it. Finally the much awaited tool arrived yesterday. And I thought of sharing it with fellow members along with posting the first tool application.

    The Steermatic battery had completely drained in the past couple of days and the ECU forgot about the CVT start clutch calibration. Sadly this happens everytime if the battery is disconnected or it completely discharges.

    So instead of the old "drive upto 60 and decelerate method" suggested in ESM, I thought of putting the tool to some use.


    But before I proceed, I must thank the one person who made it possible for me to decide. Without his input, I would have ended up with a wrong choice or some chinese clone.

    The one and only, our teacher, our automotive mentor, our guru and our respectful elder brother @Xulfiqar bhai.

    Thanks alot Xulfiqar bhai.

    CVT Start Clutch Calibration  The AUTEL Way -1457468

    CVT Start Clutch Calibration  The AUTEL Way -1457469



    Question: So whats my point:

    The point is: when your CVT starts giving poor idle in D (excessive vibarations), and idles itself all fine in N, you would want to calibrate you r transmission start clutch. Most Honda dealerships and some "gheroo-program" mechanics advise throttle body service, engine/tranny mounting replacements, valve body replacements and what not.

    However, its just a couple of steps in procedure to get it back on road hassle free.

    Happy CVT driving. Cheers

    JazakAllah

    Any ideas if this is equally valid for a Toyota Vitz as well?
    Get over the fact that Xli lacks power windows, Its an Xli because it lacks thoose features or else it would be a Gli or an Altis if had all the goodies.

    Its valid for all CVTs available with start clutch. (Vario, Steerio)

    EDIT:VITZ Removed from this list. Please refer HERE for more information

    I am not sure if the Toyota Axio and Premio (available here in PK) pack inside a Torque convertor or clutch, but I know that the 5th gen City supplied internationally comes with a CVT+TC and hence no calibration is required.

    One has to observe the symptoms. But theoratically, the tranny should disengage from engine if the output shaft speed sensor reads a zero speed and brake peddle is pressed. Example, in steerio, the clutch disengages about 1 sec after the car comes to a halt with brake pedal pressed. It re-engages about 0.75 sec after brake is released. and then the car starts crawling.

    thats another method to calibrate the Honda City with CVT.

    Let me copy paste from ESM.

    Calibration Procedure with Driving the Vehicle

    1. Warm up the engine to normal operating temperature (the radiator fan comes on).

    2. Start the engine under no-load conditions, then turn the headlights on.

    3. Start off in [D] position, and drive the vehicle until vehicle speed reaches 60 km/h (37 mph), then decelerate the vehicle in more than 5 seconds without pressing the brake pedal to reach completion.

    4. Test-drive the vehicle to verify that a problem does not occur on the start clutch control system.

    what i get from the bold lines is that when you are on 60 Km/h after 5 seconds decelerate without braking.. so we have to decelerate to 0 or what?

    There is yet another method by jumping the SCS line. However, i wont paste it here as someone may make a mistake in jumping the SCS in DLC and may put himself into more trouble.

    Also, the jumping SCS method did not work for me. However, i didnt try it on a Vario.

    No. No.

    Just when you reach 60, let go of the gas peddle for about 5 seconds. Allow the vehicle to decelerate itself.

    Then after 5 seconds, increase speed again to 60 and repeat the above procedure 3 to 4 times.

    The headlight on signal is important. This was also required by MaxiDAS.
