An open wire.
An open taillight switch.
A blown fuse.
A burned bulb.

2. The number 2 and 3 cylinders of a four cylinder engine are producing less secondary voltage than the 1 and 4 cylinders. According to the diagram above which of the following is causing this condition?

There is an open at point A of the ignition system.
There is an open at point C of the ignition system.
There is resistance at point C of the ignition system.
There is resistance at point D of the ignition system.

3. If a technician reversed the leads of a digital voltmeter on a 12 volt circuit the readout would show:

0.00 volts
-0.00 volts
12.00 volts
-12.00 volts

4. The hazard and turn signal lights are inoperative. Technician A says that they share the same circuit. Technician B says the vehicle may have a faulty flasher. Who is correct?

Technician A
Technician B
Both A and B
Neither A or B

5. All of the following are true about the circuit in the diagram above EXCEPT.

It is a ground switched circuit.
It contains two relays.
The solid dots indicate a junction.
It is a positive pulse relay circuit.

6. The power door locks in the vehicle in the diagram above unlock only. There is no locking action. Which of the following is causing this condition?

Relay A
Relay B
Switch A
Fuse A

7. Two technicians are discussing diagnostics and the data link connector. Technician A says the OBD II DLC connector is located in the cabin near the steering wheel. Technician B says to use this connector to test resistance in the CAN (Controller Area Network). Who is correct?

Technician A
Technician B
Both A and B
Neither A or B

8. A CAN controller area network is being discussed. Which of these is correct?

The CAN now operates at 1Mbps.
The CAN contains twisted wires to prevent RFI interference.
The low speed CAN connects to the ECM and the TCM.
The high speed CAN connects to the mirror and seat controller.

9. A vehicle is overheating. The electric radiator cooling fan in the illustration does not operate under any condition. All of the following result in an inoperative fan motor EXCEPT?

A short to ground at point A of the system.
An open at point B in the system.
An open at point C in the system.
An open at point D of the system.

10. A pedal mounted brake switch is being tested with a voltmeter. The pedal is depressed, and there is power at the switch, but no power coming out. Technician A says with the brake pedal depressed, there should be power present at both ends of the brake switch. Technician B says this condition indicates that there is an open in this brake switch. Who is correct?

Technician A
Technician B
Both A and B
Neither A or B

11. The electrical symbol above is:

A resistor.
A splice.
An inductor.
A motor.

12. Two technicians are discussing a burned fuse element in a fan circuit. Technician A says the burned fuse was caused by high resistance in the fan circuit. Technician B says the burned fuse was the result of an open in this circuit. Who is correct?

Technician A
Technician B
Both A and B
Neither A or B

13. Technician A says a faulty cruise control switch can result in an inoperative cruise control system. Technician B says the cruise control system may not disengage if there’s a problem with the brake switch. Who is correct?

Technician A
Technician B
Both A and B
Neither A or B

14. An electric seat will not move backward or forward. A noise is heard coming from the seat when the switch is pressed. The MOST likely cause of this problem is:

A short to ground between the power source and the seat.
A napkin wedged into the seat rail.
An intermittent open in the connection between the power source and the seat motor.
A loose plug from the harness to the seat motor.

15. Two technicians are discussing an analog transmission range sensor on a late model vehicle. Technician A says that since these sensors use resistance to indicate gear selection, they can be tested with an ohmmeter. Technician B says to start the car and make sure the circuit is powered before using the meter. Who is correct?

Technician A
Technician B
Both A and B
Neither A or B

16. Which solder should be used when repairing an automotive electrical connection.
