Data List / Active Test [10/2014 - ]

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

HINT: 

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.

  1. DATA LIST OF 4WD ECU ASSEMBLY

  2. ACTIVE TEST OF 4WD ECU ASSEMBLY 

    HINT: 

    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. Enter the following menus: Chassis / Four Wheel Drive / Active Test.
    5. According to the display on the Techstream, perform the Active Test.

      Chassis > Four Wheel Drive > Active Test
