System information


DATA LIST

NOTICE:
  1. The DATA LIST values may vary significantly if there are slight differences in measurement, differences in the environment in which the measurements are obtained, or the aging of the vehicle. Thus, definite standards or judgment values are unavailable. Therefore, there may be a malfunction even if a measured values is within the reference range.
  2. In the event of intricate symptoms, collect sample data from another vehicle of the same model operating under identical conditions in order to reach an overall judgment by comparing all the items of DATA LIST.

HINT:
Using the DATA LIST displayed on the intelligent tester, you can read values including those of the switches, sensors, actuators, without removing any parts . Reading the DATA LIST as the first step of troubleshooting is one method to shorten diagnostic time.

  1. Connect the intelligent tester to the DLC3.

  2. Turn the ignition switch to the ON position and turn the intelligent tester on.

  3. Select the following menu items: Powertrain / Hybrid Control / Data List.

  4. Check the results by referring to the following table.

ACTIVE TEST

NOTICE:
Beware that if the connector to the intelligent tester becomes disconnected or if a communication error occurs during the ACTIVE TEST, the vehicle could become inoperative (the READY light goes off).

  1. Connect the intelligent tester to the DLC3.

  2. Turn the ignition switch to the ON position and turn the intelligent tester on.

  3. On the System Select screen, enter the following menus: Powertrain / Hybrid Control / Active Test.

  4. According to the display on the tester, perform ACTIVE TEST.
