Lighting System (For Hatchback) -- Data List / Active Test



DATA LIST
HINT:
Using the Techstream 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.
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.

  1. Connect the Techstream to the DLC3.

  2. Turn the ignition switch to ON.

    1. for Main Body ECU: Body Electrical / Main Body / Data List.
