DATA LIST / ACTIVE TEST
1. READ DATA LIST
HINT:
Using the intelligent tester's DATA LIST allows switch,
sensor, actuator and other item values to be read without
removing any parts. Reading the DATA LIST early in
troubleshooting is one way to save time.
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON.
(c) Read the DATA LIST according to the display on the
tester.

2. PERFORM ACTIVE TEST
HINT:
Performing the intelligent tester's ACTIVE TEST allows
relay, VSV, actuator and other items to be operated
without removing any parts. Performing the ACTIVE
TEST early in troubleshooting is one way to save time.
The DATA LIST can be displayed during the ACTIVE
TEST.
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON.
(c) Perform the ACTIVE TEST by following the
directions on the tester screen.
