  2. ACTIVE TEST 

    HINT:

    Performing the ACTIVE TEST using the hand-held tester allows the relay, actuator and so on to operate without removing any parts. Performing the ACTIVE TEST as a first step of troubleshooting is one of the methods to shorten the labor time.

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

    1. Connect the hand-held tester to the DLC3.
    2. Turn the ignition switch to the ON position.
    3. From to the display on the tester, select the "ACTIVE TEST".

    HINT:

    IG must be turned ON to proceed Active Test using a hand-held tester.
