DYNAMIC RADAR CRUISE CONTROL SYSTEM DATA LIST / ACTIVE TEST


  1. DATA LIST

    Tech Tips

    Using the intelligent tester to read the Data List allows 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 tester on.

    4. Entire the following menus: Powertrain / Radar Cruise / Data List.

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

  2. ACTIVE TEST

    Tech Tips

    Using the intelligent tester to perform Active Test allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Test early in troubleshooting is one way to save diagnostic time. Data List information can be display while performing Active Test.


    1. Connect the intelligent tester to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the tester on.

    4. For Cruise Main Indicator Light (Combination Meter):

      Enter the following menus: Body Electrical / Combination Meter / Active Test.

    5. For Skid Control Buzzer (ABS / VSC / TRA):

      Enter the following menus: Chassis / ABS / VSC / TRA / Active Test.

    6. Perform Active Test according to the display on the tester.

      Tech Tips

      The power switch must be turned on (IG) to proceed with the Active Test using the tester.
