      Check absorber control actuator operation:


      1. Starting from the above mentioned position, as the brake pedal is depressed, the absorber control actuator position will increase by 2 steps (1 (SOFT) → 3 → 5 → 7 → 9 → 11 → 13 → 15 → 17 (HARD)). At this time, bounce the vehicle and check that the shock absorber is becoming harder.

        Tech Tips


        • Every time the brake pedal is depressed, the absorber control actuator rotates in the hard to soft direction in 15° intervals up to a maximum angle of 120°.

        • To hold the absorber control actuator at a specific position, adjust it using the above mentioned procedure, then increase the vehicle speed to 5 km/h (3 mph). After that, the absorber control actuator position does not change until the engine switch is turned off.

        • If the absorber control actuator does not operate, inspect the absorber control actuator circuit and absorber control actuator installation condition.

  2. CHECK CONNECTIONS OF TUBES FOR AIR LEAKAGE


    1. Set the height control switch to the "HEIGHT HIGH" position and raise the vehicle height.

    2. Stop the engine.

    3. Apply soapy water to the connections of the tubes and check if there is any air leakage.
