METER / GAUGE 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. Warm up the engine.

    2. Turn the engine switch off.

    3. Connect the intelligent tester to the DLC3.

    4. Turn the engine switch on (IG).

    5. Turn the intelligent tester on.

    6. Enter the following menus:


      1. for Combination Meter: Body / Combination Meter / Data List.

      2. for ABS/TRC/VSC: Chassis / ABS/VSC/TRC / Data List.

      3. for Engine and ECT: Powertrain / Engine and ECT / Data List.

    7. Check values by referring to the table below.

  2. ACTIVE TEST

    Tech Tips

    Using the intelligent tester to perform Active Tests allows the 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 trouble shooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.


    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the intelligent tester on.

    4. Enter the following menus:


      1. for Combination Meter: Body / Combination Meter / Active Test.

      2. for Body: Body / Body (Main Body ECU RH) / Active Test.

    5. Check each operation by referring to the table below.
