Electrical II week 4

1.      Technician A says the data displayed on the Driver Information Center (DIC) can come from the VCM (Vehicle Control Module) or BCM (Body Control Module).  Technician B says the entire instrument panel assembly may have to be replaced even if just one unit fails.  Who is right?

• Technician A
• Technician B
• Both Technicians
• None of the Technicians

1.      Technician A says a LCD (Liquid Crystal Display) may be slow to work at high temperatures.  Technician B says that the LCD dash display can be damaged, when pressure is exerted on the front of the display during cleaning.  Who is right?

• Neither Technician A nor B is right
• Technician B is right
• Both Technicians A and B are right
• Technician A is right

1.      Which of these is a type of electric motor designed to rotate in small steps based on the signal from a computer:

• A.       Stepping motor

• B.       Compound motor

• C.       Stepper motor

• D.       Shunt control motor

Which of the following actions will deactivate cruise control operation?

• Turn on the hazard lights
• Change the radio station
• Tap the brake pedal or press the cancel button on the steering wheel
• Adjust the side mirrors

The brake warning lamp on the dash remains on whenever the ignition is on.  Technician A says this could be low fluid in the hydraulic system.  Technician B says the problem is probably due to a stuck parking brake caliper switch.  Who is right?

• Technician B
• Technician A
• Both Technicians
• None of the Technicians

1.      Why does changing tire diameter affect the speedometer reading?

• The radio reception gets better
• The distance traveled with each revolution of the tire changes
• The engine power decreases
• The color of the tire changes

1.      Which of these electronic display devices uses electrodes and polarized fluid to create numbers and characters:

• LCD (Liquid Crystal Display)
• OLED (Organic Light Emitting Diode)
• CRT (Cathode Ray Tube)
• LED (Light Emitting Diode)

1.      Which of these is the MOST likely reason why warning lamps replaced gauges in some vehicles:

• To make the vehicle more visually appealing
• Cost and simplicity of installation
• To improve the accuracy of the readings
• To increase the weight of the vehicle

1.      Temperature compensation in bimetallic gauges is accomplished by:

• Using only one type of metal with the same coefficient of thermal expansion
• Using plastic instead of metal
• Not compensating for temperature changes at all
• Using two different metals with different coefficients of thermal expansion
