0.368 Volts - ANS-A digital multimeter (DMM) set on the mV scale has a display reading
of 368. Which of these values does the reading represent?
0.450 volts - ANS-A digital multimeter (DMM) reading of 450 mV is equal to:
0.728 - ANS-On a Metric Micrometer upper sleeve reading 5.0mm with lower sleeve
reading 0.50mm and a thimble reading of 0.01mm what is the overall reading?
300 amps for 15 seconds - ANS-A fully charged battery rated at 600 CCA, the ambient
temperature is 70 degrees which of these current and time periods should be used?
A CVT can change steplessly through an infinite number of effective gear ratios
between maximum and minimum values - ANS-Which of these best describes the
operation of a continuously variable transmission (CVT)?
A loose accessory drive belt - ANS-A vehicle has a squealing noise that changes with
engine speed. This could be caused by:
A only - ANS-A driveshaft universal joint is being replaced and the technician cannot
install the retaining clip. Technician A says that a dislocated needle bearing could be the
cause. Technician B says that a damaged spline in the yoke could be the cause. Who is
right?
A only - ANS-A floating front brake caliper is being replaced. Technician A says that
after installation, the brake hose to caliper fitting should be checked for leaks.
Technician B says that both caliper pins should be lubricated with DOT 4 brake fluid.
Who is right?
A only - ANS-A vehicle is being checked for power steering fluid leaks. Technician A
says that leaks can develop in the fittings, hoses, and seals. Technician B says that the
steering components should be observed for leaks while a helper turns the steering
wheel to the right and left. Who is right?
A only - ANS-Both front wheels are to be removed from a vehicle. Technician A says
that if a floor jack is to be used to raise the vehicles, the vehicle should be supported
with jack stands. Technician B says that if an electric lift is to be used to raise the
vehicle, jack stands should be placed at the four corners of the vehicle. Who is right?
, A only - ANS-During an instruction panel gauge test, the technician observes that the
engine temperature gauge is reading 200 F (93 C) on a cold engine. Technician A says
that a scan tool can be used to compare the gauge reading to the coolant temperature
sensor reading. Technician B says that an open coolant thermostat could be the cause.
Who is right?
A only - ANS-Technician A says that a positive crankcase ventilation (PCV) system
reduces vehicle emissions. Technician B says that a positive crankcase ventilation
(PCV) system helps increase crankcase pressure. Who is right?
A only - ANS-Technician A says that disconnecting the negative battery cable may be
required to disable the air bag system. Technician B says that a self-powered test light
can be used to test air bag system components. Who is right?
A only - ANS-Technician A says that disconnecting the negative battery cable may be
required to disable the airbag system. Technician B says that a self-powered test light
can be used to test air bag system components. Who is right?
A only - ANS-Technician A says that excessive play of the inner tie rod indicates that the
inner tie rod must be replaced. Technician B says that a torn bellows boot on the rack
and pinion indicates that the outer tie rod end must be replaced. Who is right?
A only - ANS-Technician A says that eye protection should be worn at all times while in
the laboratory area. Technician B says that regular prescription eyewear may be worn
as a substitute for safety glasses. Who is right?
A only - ANS-Technician A says that rosin-core solder should be used when soldering
electrical connections. Technician B says that a crimp and shrink connector can be used
when repairing electrical wiring. Who is right?
A only - ANS-Technician A says that tire rotation helps to extend tire lief. Technician B
says that directional tires should be rotated in an "X" pattern. Who is right?
A only - ANS-Technician A says that, when reinstalling a wheel and tire assembly on a
vehicle, the lug nuts should be tightened using a torque wrench. Technician B says that,
when reinstalling a wheel and tire assembly on a vehicle, the lug nut should be
tightened in a circular pattern. Who is right?
