ACTIVE TEST
Performing the ACTIVE TEST using the hand±held tester allows the meters, indicators and so on to operate
without part removal. Performing the ACTIVE TEST as the first step of troubleshooting is one way to shorten
labor time.
It is possible to display the DATA LIST on the hand±held tester during the ACTIVE TEST.
(a) Connect the hand±held tester to the DLC3.
(b) Turn the ignition switch to the ON position.
(c) From the display on the tester, perform the ºACTIVE TESTº.
