DATA LIST/ACTIVE TEST
1. DATA LIST
HINT:
According to the DATA LIST displayed by the hand −held tester, you can read the value of the switch, sensor,
actuator and so on without parts removal. Reading the DATA LIST as the first step of troubleshooting is one
method to shorten labor time.
(a) Warm up the engine.
(b) Turn the ignition switch off.
(c) Connect the hand −held tester to the DLC3.
(d) Turn the ignition switch to the ON position.
(e) Push the ”ON” button of the hand −held tester.
(f) Select the item ”DIAGNOSIS / OBD/MOBD / DATA LIST”.
(g) According to the display on tester, read the ”DATA LIST”.
