Scan Tool Testing and Procedures

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 power switch ON (IG).
c. Read the DATA LIST.












2. PERFORM ACTIVE TEST

NOTICE: Be careful to avoid injuries as this test causes vehicle parts to move.

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 power switch ON (IG).
c. Perform the ACTIVE TEST by following the directions on the tester screen.
