  4. Start engine.
  5. Press "ENTER" until "LOADS OFF REV ENGINE 5 SEC" is displayed.
  6. Raise and hold the engine speed at 1, 500 to 2, 000 rpm for about 5 seconds, then return the engine to idle.

    Once the increase in engine rpm is detected, press "ENTER" to continue.

    NOTE:
    • If after 30 seconds an increase in engine idle speed is not detected, "RPM NOT DETECTED" will display.
    • Some engines may have a higher idle initially after starting, particularly when the engine is cold. The tester may detect this without any other action being taken. If this occurs, continue on with the testing process. The final results will not be affected.
