LEXUS PARKING ASSIST-SENSOR SYSTEM DATA LIST / ACTIVE TEST


  1. 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.


    1. Connect the intelligent tester to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the intelligent tester ON.

    4. Enter the following menus:


      1. Select: Body / (desired system) / Data List /

    5. According to the display on intelligent tester, read the "Data List".

  2. ACTIVE TEST

    Tech Tips

    Performing the Active Test enables components including relay, VSV (Vacuum Switching Value), actuators and other items to be operated without removing any parts. The Active Test can be performed with an intelligent tester. Performing an Active test as the first step in troubleshooting is one method of shortening diagnostic time. Data List information can be displayed while performing Active Tests.


    1. Connect the intelligent tester to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the intelligent tester ON.

    4. Enter the following menus:


      1. Select: Body / (desired system) / Active Test /

    5. According to the display on intelligent tester, perform the "Active Test".
