Data List / Active Test

  1. DATA LIST 

    HINT:

    By referring to the Data List displayed on the Techstream, the value and status of parts such as switches, sensors and actuator can be read without removing any parts. Reading the Data List as the first step of troubleshooting is one method of shortening diagnostic time.

    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Turn the tester on.
    4. Select the following menu items: Chassis / ABS/ VSC/TRAC / Data List

  2. ACTIVE TEST 

    HINT:

    Performing the Active Test using the Techstream allows relays and actuators to be operated without removing any parts. Performing the Active Test as the first step of troubleshooting is one method of shortening diagnostic time.

    It is possible to display the Data List during the Active Test.

    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Turn the tester on.
    4. Select the following menu items: Chassis / ABS/ VSC/TRAC/ Active Test
    5. By following the prompts on the tester, perform the Active Test.

      HINT:

      • The ignition switch must be turned to ON to proceed to the Active Test using the Techstream.
      • The motors stop automatically after 5 seconds of activation to prevent them from being damaged. When repeatedly activated, certain intervals are required.
      • Each solenoid stops automatically after 2 seconds of activation to prevent them from being damaged, and can be operated again after a certain interval.
      • Do not depress the brake pedal while only the pressure reduction solenoid valves are on.
      • Do not drive 2 or more solenoids simultaneously except to operate the pressure holding solenoid valves and pressure reduction solenoid valves of each wheel.
