9 Questions

1. Two technicians are explaining the use of high voltage rubber gloves when servicing hybrid electric vehicles or plug-in hybrid electric vehicles. Technician A says that you must be sure that the gloves are rated at least 500 volts and class "1" by American National Standards Institute/American Society for Testing Materials (ANSI/ASTM). Technician B says that leather gloves should be worn over the high-voltage rubber gloves to protect the rubber gloves from damage. Who is right?
2. A plug-in hybrid electric vehicle will enter the POWER ON (Key On Engine Off) mode, but will not go into the READY TO DRIVE (Key On Engine Running) mode. There is no diagnostic trouble code in history or active. Which of the following could be the cause?
3. The internal combustion engine on an older Ford hybrid electric vehicle will still not crank after a minor front collision and there is a stored diagnostic trouble code B2171 Inertia Input Switch Circuit open with no messages shown. Which of the following could be the cause?
4. On a Type-3 hybrid vehicle, the high-voltage battery pack falls to a predetermined state-of-charge, but the internal combustion engine (ICE) fails to start and it is in the READY TO DRIVE (KOER) mode. Which of the following is the most likely cause?
5. The internal combustion engine on an older Ford hybrid electric vehicle will still not crank after a minor front collision and there is a stored diagnostic trouble code B2171 Inertia Input Switch Circuit open with no messages shown. Which of the following could be the cause?
6. Which of the following is least likely to cause a problem in electric vehicle supply equipment (EVSE)?
7. Technician A says you can use a digital multimeter (DMM) to check the resistance between negative and ground while cranking the starter. Technician B says to check the voltage drop between (+) positive and the starter terminal stud while the starter is cranking. Who is right?
8. Using a DMM (Digital Multimeter), on a fully charged 12-volt hybrid electric vehicle auxiliary battery, how much voltage should the open circuit voltage (OCV) test show?
9. What color plastic conduit identifies 144 to 600 voltage cables in hybrid electric vehicles and plug-in hybrid electric vehicles?
