ACTIVE STABILIZER SUSPENSION SYSTEM DATA LIST / ACTIVE TEST


  1. READ DATA LIST

    Tech Tips

    Using the intelligent tester to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

    Note

    In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.


    1. Turn the power switch off.

    2. Connect the intelligent tester to the DLC3.

    3. Turn the power switch on (READY) and turn the intelligent tester on.

    4. Enter the following menus (Front active stabilizer): Chassis / Front Stabilizer / Active Test.

    5. Perform the Active Test by following the prompts on the intelligent tester.

      Front Stabilizer
      Tester Display Test Part Control Range Diagnostic Note
      Stabilizer Check Forced operation of front active stabilizer control actuator

      When turned ON, 1 to 6 below are performed in 1 sec. intervals


      1. Vehicle front tilts to right side

      2. Above position is maintained

      3. Vehicle returns to original position

      4. Vehicle front tilts to left side

      5. Above position is maintained

      6. Vehicle returns to original position

      		 If operation is prohibited through fail-safe control, Active Test cannot be performed

      Note

      During the Active Test, do not drive the vehicle.
