Who is correct?

  • A. Technician A
  • B. Technician B
  • C. Both A and B
  • D. Neither A or B
Air suspension system.

66.

Answer A is wrong. A sticking or an intermittent problem with the air spring solenoid valve would prevent the left rear air spring from inflating or deflating.

Answer B is wrong. A rusty and sticking vent/exhaust valve on the compressor will prevent any air spring from deflating after removing weight. The vehicle will not lower once raised.

Answer C is correct. Both technicians are correct.

67. A vehicle's steering wanders while driving forward, drifting from one side of the road to the other. Technician A says this condition could be caused by loose tie rod ends. Technician B says to rock the tire back and forth at the three and nine o'clock positions to check for tie rod looseness. Who is correct?

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

67.

Answer A is wrong. Both technicians are correct. Loose tie rods result in vehicle wander and excessive tire wear.

Answer B is wrong. Place your hands at the three and nine o'clock positions and rock the tire left then right to check for tie rod looseness.

Answer C is correct. Both technicians are correct.

Answer D is wrong. Both technicians are correct.

Illustration of tire wear.

68. Which of the following is true about the tire in the illustration?

  • A. It is underinflated.
  • B. It is overinflated.
  • C. There is too much camber.
  • D. The coil spring on that wheel is weak.

68.

Answer A is wrong. An underinflated tire will show premature wear on its shoulders.

Answer B is correct. Overinflating wears the center of a tire's tread.

Answer C is wrong. Too much camber wears the tire's inner or outer tread.

Answer D is wrong. Weak coil springs cause tire cupping.

Automotive tool.

69. Technician A says the tool in the illustration is for static calibration of the vehicle's ADAS sensors. Technician B says to perform dynamic ADAS calibration with the vehicle on a level surface in the service bay. Who is correct?

  • A. Technician A
  • B. Technician B
  • C. Both A and B
  • D. Neither A or B
ADAS sensor calibration tool.

69.

Answer A is correct. The dotted targets are used to calibrate the rearview mirror camera used by the Lane Departure Assist system.

Answer B is wrong. Calibrate the rearview mirror camera with a scan tool and targets in the service bay, and perform dynamic calibration at certain speeds and distances during a test drive.

Answer C is wrong. The Lane Departure Assistance system warns the driver when the vehicle drifts out of its lane. It uses EPS electric power steering, the ABS brake system, or both to keep the vehicle centered.

Answer D is wrong. Read more about Lane Keep and Park Assist systems by clicking the Read More button.

70. A technician is bleeding air from a hydraulic power steering system. All of the following are true about bleeding hydraulic power steering systems EXCEPT:

  • A. Raise the front tires off the ground.
  • B. Turn the steering wheel left and right from stop to stop to remove air from the system.
  • C. Flush with clean power steering fluid.
  • D. Hold the wheel against each steering stop for at least ten seconds.

Answer A is wrong. The tires are raised in the air to prevent flat spots.

Answer B is wrong. Turn the wheel left and right from stop to stop to bleed air from the system.

Answer C is wrong. Use the recommended fresh power steering fluid.

Answer D is correct. Do not hold the wheel against the steering stops for more than five seconds. Doing so quickly increases system pressure and can damage power steering components.
