6. Hybrid safety is being discussed. Technician A
says you should remove all jewelry before
working on a hybrid’s high-voltage circuits.
Technician B says you should always wear
rubber-soled shoes when working on a hybrid
vehicle. Who is right?
(A) A only.
(B) B only.
(C) Both A and B.
(D) Neither A nor B.
7. When working on hybrid power cables and
other high-voltage components, you should
wear gloves with an insulation value of:
(A) 50 volts.
(B) 100 volts.
(C) 500 volts.
(D) 1000 volts.
8. Technician A says that when towing a front-
wheel drive hybrid, the front wheels should be
raised off the ground. Technician B says that
when towing an all-wheel drive hybrid with
motor-generators at the front and rear, all four
wheels must be raised off the ground. Who is
right?
(A) A only.
(B) B only.
(C) Both A and B.
(D) Neither A nor B.
9. A hybrid battery pack must be recharged.
Technician A says that a standard 12-volt bat-
tery charger can be used to recharge the battery
pack. Technician B says that a battery pack
that will not take a full charge must be
replaced. Who is right?
(A) A only
(B) B only.
(C) Both A and B.
(D) Neither A nor B.
10. Trouble codes indicate a high battery tempera-
ture and an infrared thermometer is used to
check the temperature of individual cells.
Technician A says that if only one cell is warm,
it is probably shorted and the battery pack must
be replaced. Technician B says that if all the bat-
tery cells are warm, there may be a problem
with the battery cooling system. Who is right?
(A) A only
(B) B only.
(C) Both A and B.
(D) Neither A nor B.
Activities—Chapter 38
1. Inspect a hybrid vehicle. Locate the battery
pack, power control module, power display,
engine, power cables, and other parts. Make
sure you wear insulated gloves and eye protec-
tion during your inspection.
2. Use the Internet to look up gas mileage figures
for several cars, including gas engine only and
hybrid vehicles. Write a report on which vehi-
cles get the highest gas mileage and why.
3. Look up service data on a hybrid vehicle. Write
a report summarizing what must be done to
remove and replace the battery pack, power con-
trol module, or other parts of the hybrid drive.
