| ACTIVE TEST |
- HINT:
- Performing the Active Test using the intelligent tester allows the relay, actuator, etc. to operate without removing any parts. Performing the Active Test as the first step of troubleshooting is one of the methods to shorten labor time.
- It is possible to display the Data List during the Active Test.
Connect the intelligent tester to the DLC3.
Turn the engine switch on (IG).
From the display on the tester, select the Active Test.
- HINT:
- The engine switch must be turned on (IG) to proceed to the Active Test using the intelligent tester.
