Operation Check

  1. CHECK ABSORBER CONTROL ACTUATOR OPERATION 
    1. Remove the actuator with its connectors still connected.
    2. Turn the engine switch off.
    3. Using SST, connect the terminals 12 (TS) and 4 (CG) of the DLC3.

      SST 09843-18040 

    4. Start the engine.

    5. Check that the absorber control indicator light "SPORT" is blinking in test mode.

      HINT:

      If the absorber control indicator light does not blink, inspect the indicator circuit and TS and CG terminal circuit.

    6. 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.

        HINT:

        • 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 in 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.
