DYNAMIC RADAR CRUISE CONTROL SYSTEM DATA LIST / ACTIVE TEST


  1. DATA LIST

    Tech Tips

    Using the Techstream 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 Techstream to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the Techstream on.

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

    5. Read the Data List according to the display on the Techstream.

  2. ACTIVE TEST

    Tech Tips

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


    1. Connect the Techstream to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the Techstream on.

    4. For Cruise Control Indicator (Combination Meter Assembly):

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

    5. For Skid Control Buzzer Assembly:

      Enter the following menus: Body Electrical / Pre-Collision 2 / Active Test.

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

      Tech Tips

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