During idle test high RPM, what is the recommended action?

• A. Abort the test and obtain authorization to set idle speed
• B. Notify supervisor and proceed
• C. Recalibrate idle speed without authorization
• D. Continue and log

Answer: (A)

During an idle test, readings have to be taken at a precise, stable engine idle. If the engine is idling at a higher than specified RPM, the test conditions aren’t met and the results won’t be valid. The correct action is to abort the test and obtain authorization to adjust the idle speed to the proper specification before continuing. This keeps the test in compliance and ensures the emission readings reflect the vehicle under the correct idle condition. Proceeding with the high RPM, recalibrating without authorization, or logging and continuing would produce unreliable data and could violate procedures. If you encounter a high idle, stop the test and address the idle setting through the proper authorized channel before retesting.
