Data List / Active Test
- 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.
- Connect the intelligent tester to the DLC3.
- Turn the engine switch on (IG).
- Read the DATA LIST according to the display on the tester.

- 1 is OK, but CRUISE main indicator light does not illuminate → Cruise main indicator light, wire harness, or ECM failure
- ACTIVE TEST
HINT:
Performing the intelligent tester's ACTIVE TEST allows relays, VSVs, actuators, 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.
- Connect the intelligent tester to the DLC3.
- Turn the engine switch on (IG).
- Perform the ACTIVE TEST according to the display on the tester.
HINT:
The engine switch must be turned on (IG) to proceed to the ACTIVE TEST using the intelligent tester.
