Engine Immobiliser System (For Hatchback) -- Data List / Active Test



DATA LIST
HINT:
  1. 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.
  2. If the ignition switch cannot be turned to ON, communication with the Techstream can be performed by connecting the Techstream to the vehicle and turning a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the Techstream and vehicle begins.
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.

  3. Turn the Techstream on.

  4. Enter the following menus: Body Electrical / Immobiliser / Data List.

  5. Enter the following menus: Powertrain / Engine and ECT / Data List.

  6. According to the display on the Techstream, read the Data List.
