ASE Certifi cation-Type Questions
1. Technician A says that the 1st, 2nd, and 3rd alphanumeric
characters in a hybrid’s VIN identifi es the vehicle.
Technician B says the 5th, 6th, and 7th alphanumeric
characters in the VIN identify the vehicle. Who is right?
(A) A only.
(B) B only.
(C) Both A and B.
(D) Neither A nor B.
2. 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.
3. Technician A says that when working on hybrid
power cables and other high-voltage components,
you should wear gloves with an insulation value of
100 volts. Technician B says you should use OSHA
approved “lineman gloves.” Who is right?
(A) A only.
(B) B only.
(C) Both A and B.
(D) Neither A nor B.
4. 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.
5. Technician A says that you must wait at least three
minutes after removing the high-voltage disconnect
before working on the high-voltage capacitors in
the inverter circuit. Technician B says that after you
remove the high-voltage disconnect, you should
remove the high-voltage fuse and keep it in your
pocket. Who is right?
(A) A only.
(B) B only.
(C) Both A and B.
(D) Neither A nor B.
6. A hybrid battery pack must be recharged.
Technician A says that a standard 12-volt battery
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.
7. Trouble codes indicate a high battery temperature,
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 battery 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.
8. Technician A says the most common reason for
battery pack replacement is physical damage.
Technician B says hybrid battery packs are usually
located in the engine compartment, near the motor-
generator. Who is right?
(A) A only.
(B) B only.
(C) Both A and B.
(D) Neither A nor B.
9. A circuit board in the power control module has
failed. Technician A says to check the cooling system.
Technician B says the failed circuit board should be
replaced. Who is right?
(A) A only.
(B) B only.
(C) Both A and B.
(D) Neither A nor B.
10. Technician A says a motor-generator can fail if the
car is hit by lightning or used for an extended period.
Technician B says a failed motor-generator will not
affect drive performance. Who is right?
(A) A only.
(B) B only.
(C) Both A and B.
