Data List / Active Test

  1. READ DATA LIST 

    HINT:

    According to the DATA LIST displayed on Techstream, the value and status of the switch, sensor, actuator, etc. can be obtained without part removal. Reading the DATA LIST as the first step in troubleshooting is one way to save time.

    1. Connect Techstream to the DLC3.
    2. Turn the power switch ON (IG) and press Techstream main switch ON.
    3. From the display on the tester, read the "DATA LIST".

  2. PERFORM ACTIVE TEST 

    HINT:

    Performing the ACTIVE TEST using Techstream allows the relay, actuator, etc. to operate without parts removal. Performing the ACTIVE TEST as the first step of troubleshooting is one way to save time.

    It is possible to display the DATA LIST during the ACTIVE TEST.

    1. Connect Techstream to the DLC3.
    2. Turn the power switch ON (IG) and press Techstream main switch ON.
    3. According to the display on the tester, perform the "ACTIVE TEST".
