- NOTICE:
- Inspect the fuses for circuits related to this system before performing the following inspection procedure.
| 1.PERFORM ACTIVE TEST USING INTELLIGENT TESTER (OPERATE C/OPN RELAY) |
Connect an intelligent tester to the DLC3.
Turn the ignition switch to ON and turn the tester on.
Enter the following menus: Powertrain / Engine and ECT / Active Test / Fuel Pump/Speed.
Check whether the fuel pump operation sound occurs when performing the Active Test on the tester.
- OK:
- Fuel pump operating sound occurs.
