  3. INSPECT FRONT ACTIVE STABILIZER CONTROL ACTUATOR ASSEMBLY


    1. Turn the engine switch off.

    2. Disconnect connector z43 of the front active stabilizer control actuator assembly from the front active stabilizer control ECU assembly.

    3. Check the front active stabilizer control actuator assembly.

      Standard Resistance
      Tester Connection Condition Specified Condition
      z43-2 (U) - Body ground Always 100 kΩ or higher
      z43-1 (V) - Body ground Always 100 kΩ or higher
      z43-3 (W) - Body ground Always 100 kΩ or higher

    4. Using a milliohmmeter, check the front active stabilizer control actuator assembly.

      Standard Resistance
      Tester Connection Condition Specified Condition
      z43-2 (U) - z43-1 (V) Always 96 to 212 mΩ
      z43-1 (V) - z43-3 (W) Always 96 to 212 mΩ
      z43-3 (W) - z43-2 (U) Always 96 to 212 mΩ

    5. Connect connector z43 of the front active stabilizer control actuator assembly to the front active stabilizer control ECU assembly.
