Both A and B - Technician observes that the brake fluid level is at the "Min" mark in the master cylinder
reservoir. Tech A says that worn front pads could be the cause. Tech B says that a leak in the brake
hydraulic system could be the cause. Who is right?
A only - The tires of a vehicle are being rotated and balanced. Tech A says that the wheel weight
retaining clips must be matched to the rim profile. Tech B says that directional tires are rotated in a criss-
cross pattern. Who is right?
Safely exit the building - When a shop fire cannot be immediately contained, the best thing to do is warn
others in the area, and:
300 amps for 15 seconds - A fully charged battery rated at 600 CCA, the ambient temperature is 70
degrees which of these current and time periods should be used?
B only - A vehicle's halogen headlamp bulbs are being replaced. Technician A says the glass part of the
bulb can only be handled with bare hands. Technician B says the headlamp may need to be removed.
Who is right?
0.728 - 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?
A only - The fuel filter on a fuel-injected vehicle is being replaced. Tech A says the fuel pressure should be
relieved before removing the filter. Tech B says that the arrow on the fuel filter should point towards the
fuel tank. Who is right?
The brake pedal feels low and spongy - Which of these is an indication of air in the brake hydraulic
system?
Anaerobic - Which of these cures in the absence of air?
Fluid contaminated brake linings - A grabbing brake condition can be caused by any of these EXCEPT:
Visually verify that the oil filter gasket is properly installed - When performing an oil filter change on a
vehicle with a spin on oil filter, the technician must:
Voltage regulation - A vehicle's battery prematurely fails. A charging system output test shows the
generator (alternator) is producing a constant 16.0 volts. This could indicate a failed:
Seal should be lubricated with transmission fluid - A transmission equipped with a filter is being serviced.
When installing the new filter, the:
Both A and B - While inspecting the rear axle wheel studs on a rear-wheel drive vehicle, the technician
observed that one stud is damaged. Technician A says that all the wheel studs on the hub assembly
, should be replaced. Technician B says that the thread pitch and diameter of the replacement stud must
be the same as the original. Who is right?
Neither A nor B - The three C's (concern, cause, and correction) are being reviewed on the repair order.
Technician A says that the customer's statement that the steering wheel shakes is the "correction".
Technician B says that a customer's statement about a puddle on the floor of the customer's garage is
the "cause".
Pump the brake pedal until firm - A technician installs new brake pads on the front of a vehicle. Before
the vehicle is removed from the lift the technician should:
Determine rotor minimum "machine to" thickness - When measuring parallelism of a disc brake rotor, a
technician measures 0.002" variation beyond specifications. The next step is to:
Both A and B - Technician A says that overfilling an automatic transmission can cause the transmission to
leak. Technician B says that under filling an automatic transmission can cause shifting problems. Who is
right?
Water in the lubricant - While checking the fluid level in the front differential of a four-wheel drive
vehicle, the lubricant is found to be milky and overfull. Which of these could be the cause?
A restricted cabin filter - The customer's concern is low airflow from the dash vent. This could be the
cause by:
Excessive run out in the wheel - A customer states that the left front tire loses air. Any of these could be
the cause EXCEPT:
OSHA - Which of these agencies enforces commercial workplace safety and environmental health
regulations?
A only - 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 - 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 - 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 - 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?
Replace the high-pressure hose - While inspecting a vehicle's power steering system, the technician
observes a fluid leak coming from the high-pressure hose crimp connection. To repair the leak the
technician should:
