DATA LIST / ACTIVE TEST
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) Following the display on the tester screen, read the DATA LIST.
