INSPECTION PROCEDURE

HINT:
According to the DATA LIST displayed on the intelligent tester, you can read the values of the switches, sensors, actuators and so on without parts removal. Reading the DATA LIST as the first step in troubleshooting is one method to shorten labor time.
NOTICE:
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.

READ DATA LIST

  1. Turn the engine switch off.

  2. Connect the intelligent tester together to the DLC3.

  3. Turn the engine switch on (IG).

  4. Turn the tester on.

  5. Select the item "Powertrain / Engine / Data List".

  6. According to the display on the tester, read the "DATA LIST".

    Item
    		Measurement Item / Range (Display)
    		Normal Condition
    		Diagnostic Note
