61. The shifter on the automatic transmission above will not shift out of PARK unless the shift interlock solenoid is commanded ON with a scan tool. Technician A says a faulty shift interlock solenoid has caused this condition. Technician B says a faulty brake switch could be the cause. Who is correct?

  • A. Technician A
  • B. Technician B
  • C. Both A and B
  • D. Neither A or B

61.

A shift interlock solenoid diagram.

Answer A is wrong. If the solenoid only works when commanded ON with the scan tool, inspect and test the system's inputs, like the brake switch/circuit. Check brake light operation to rule out the stoplight fuse and the brake switch as the cause.

Answer B is correct. The shift interlock solenoid/actuator is a member of the shifter assembly in the center console or the steering column. It locks the shifter in PARK until the ignition is ON and the brake pedal has been depressed.

Answer C is correct. Technician B is correct. Check the brake switch/circuit.

Answer D is wrong. Technician B is correct.

Electrical symbol

62. The electrical symbol above is :

  • A. A resister.
  • B. A capacitor.
  • C. An inductor.
  • D. A diode.

62.

Answer A is wrong. This is the symbol for a diode.

Answer B is wrong. This is the symbol for a diode.

Answer C is wrong. This is the symbol for a diode.

Answer D is correct. Diodes keep current flowing in one direction and can protect a circuit.

63. An alternator suffers from low voltage output. The alternator outputs maximum voltage when full-fielded. Which of the following is MOST likely at fault?

  • A. A burned diode.
  • B. A worn alternator brush.
  • C. A faulty regulator.
  • D. A faulty rectifier bridge.

63.

Answer A is wrong. Use a carbon pile load to keep the voltage under 15 volts.

Answer B is wrong. Answer C is correct.

Answer C is correct. Full-fielding an alternator bypasses the regulator, resulting in maximum voltage output. This is a great way to test for a faulty internal regulator.

Answer D is wrong. Answer C is correct.

64. Technician A says a fully charged lead-acid automotive battery has a specific gravity of 1.265 at 80° F. Technician B says the battery's specific gravity is affected by temperature. Who is correct?

  • A. Technician A
  • B. Technician B
  • C. Both A and B
  • D. Neither A or B

64.

Answer A is wrong. It means that it is 1.265 times heavier than the same or equal volume of water.

Answer B is wrong. For temperature adjustments, get a specific gravity reading and adjust to temperature by adding .004 for every ten degrees above 80° F and subtracting .004 for every10 degrees below 80° F.

Answer C is correct. Both technicians are correct.

Answer D is wrong. Both technicians are correct.

65. The windshield wipers on a vehicle are slow and dragging across the windshield. Technician A says this could be an open circuit at the motor's ground. Technician B says the wiper linkage may be binding. Who is correct?

  • A. Technician A
  • B. Technician B
  • C. Both A and B
  • D. Neither A or B

65.

Answer A is wrong. The windshield wipers would be inoperable.

Answer B is correct. Binding linkage will cause the wipers to drag.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.
