Data List / Active Test [10/2013 - ]

WARNING: This page is about a different variant/trim than selected.
  1. DATA LIST 

    HINT: 

    Using the Techstream 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 Techstream to the DLC3.
    2. Turn the power switch on (IG).
    3. Turn the Techstream on.
    4. Entire the following menus: Powertrain / Radar Cruise / Data List.
    5. According to the display on the Techstream, read the "Data List".

  2. ACTIVE TEST 

    HINT: 

    Using the Techstream to perform Active Tests allows relays, VSVs, actuators and 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 display while performing Active Tests.

    1. Connect the Techstream to the DLC3.
    2. Turn the power switch on (IG).
    3. Turn the Techstream on.
    4. For Cruise Control Indicator Light (Combination Meter Sub-assembly):

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

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

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

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

      HINT: 

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