  1. Start the engine and drive the vehicle until the engine coolant temperature reaches 60°C (140°F) or higher.

  1. Allow the engine to idle for 1 minute or more.

  1. Connect the GTS to the DLC3.

  1. Turn the GTS on.

  1. Enter the following menus: Powertrain / Engine and ECT / Data List / Injection Volume and Injector Feedback Val. #1 to #4.

  1. Check that the "Injector Feedback Val. #1 to #4" values are within the specification.

    Standard:

    Tester Display

    Injection Volume
    		Idling
    		3 to 10 mm3/st
    Injector Feedback Val. #1
    Injector Feedback Val. #2
    Injector Feedback Val. #3
    Injector Feedback Val. #4
    		Idling
    		-3.0 to 3.0 mm3/st
    If the result is not as specified, replace the fuel injector assembly.
