DATA LIST / ACTIVE TEST

DATA LIST

NOTICE:

  • Some Data List values may vary significantly if there are slight differences in the environment in which the vehicle is operating when measurements are obtained. Variations may also occur due to aging of the vehicle. Due to these considerations, it is not always possible to provide definite values to be used for judgment of malfunctions. It is possible that a malfunction may be present even if measured values are within the reference range.
  • In the event of a problem with 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 of the items in the Data List.

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

(d) Enter the following menus: Powertrain / Rear Motor Generator / Data List.

(e) Check the results by referring to the following table.

HINT:

  • When reviewing Data List information, try to select only the specific Data List items related to the inspection being performed. If all items are selected when checking the Data List, the interval between updates for each item will be longer, resulting in delayed or incorrect data.
  • Using a custom list makes it possible to easily select smaller groups of related Data List items.
  • The following custom lists are available:
    • All Data
    • Inverter
    • Resolver
    • DC/DC Converter
    • Resolver Learning
