FUEL SYSTEM ON-VEHICLE INSPECTION


  1. INSPECT FOR FUEL PRESSURE


    1. A01CJAHE02

      Read the Data List.


      1. Warm up the engine.

      2. Turn the ignition switch off.

      3. Replace the normal DLC3 cable (12 V specification) for the intelligent tester with the 24 V DLC3 cable.

        Note

        Be sure to use the 24 V DLC3 cable when connecting the intelligent tester to the DLC3. Using the normal DLC3 cable (12 V specification) will cause damage to the tester.

      4. Connect the intelligent tester to the DLC3.

      5. Start the engine.

      6. Turn the intelligent tester on.

      7. Enter the following menu items: Powertrain / Engine and ECT / Data List.

      8. Read the Data List.
