2. DATA LIST
HINT:
According to the DATA LIST displayed on the Hand±held tester, you can read the value and status of the
switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as a first step of trouble-
shooting is one of the methods to shorten the labor time.
(a) Connect the Hand±held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) From the display on the tester, read the ºDATA LISTº.

3. ACTIVE TEST
HINT:
Performing the ACTIVE TEST using the Hand±held tester allows the relay, solenoid, actuator and so on to
operate without parts removal. 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.
(a) Connect the Hand±held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) From the display on tester, select the ºACTIVE TESTº.
HINT:
IG must be turned ON to proceed Active Test using a hand±held tester.
