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 ignition switch off.

  2. Connect the intelligent tester together with the CAN VIM (controller area network vehicle interface module) to the DLC3.

  3. Turn the ignition switch to the ON position.

  4. Turn on the tester.

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

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