ASE A4 Steering Suspension Practice Test

6. On cold mornings, the warning lamp on a vehicle with a TPMS tire pressure monitoring system stays illuminated for several minutes before it goes out. Which of these is MOST likely the cause of this condition.

  • A. Clogged TPMS sensor.
  • B. Worn tread on one of the tires.
  • C. TPMS initialization.
  • D. Low tire pressure.

6.

Answer A is wrong. The TPMS sensor has a port to sense the tires air pressure. If the port becomes clogged, the sensor will indicate low air pressure to the module and the TPMS light will be illuminated and stay illuminated until repaired. Tires heat up as the vehicle is driven, raising the tires air pressure to acceptable levels. These levels are located on a sticker on the drivers side door or door jam.

Answer B is wrong. The TPMS sensor senses air pressure not the tread depth of the tire.

Answer C is wrong. Initialization is a process of synchronizing a sensor to the controller. It senses and registers important information like the sensors ID.

Answer D is correct. When the light stays on for several minutes of driving and then goes out, one of the tires could have low air pressure. As the tire heats from driving, the air pressure increases and the light goes out. Check all four tires and the spare for proper air pressure.

7. A front wheel drive vehicle is pulling to the left. Loose engine cradle bolts are noticed during the initial inspection. Technician A says loose engine cradle bolts will cause a vibration, but have no affect on the vehicle's steering system. Technician B says if the engine cradle is not centered before fastening the bolts, the wheel alignment angles will be affected. Who is correct?

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

7.

Answer A is wrong. A misaligned cradle will cause a vehicle to pull. Loose cradle bolts will affect the steering system.

Answer B is correct. Most cradles have alignment holes/pins that assist in cradle alignment.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.

8. Two technicians are discussing an electronic air suspension system. Technician A says the suspension switch must be turned off before lifting the vehicle. Technician B says to use soapy water to visually inspect this system for leaks. Who is correct?

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

8.

Answer A is wrong. Both technicians are correct.

Answer B is wrong. Both technicians are correct.

Answer C is correct. Lifting a vehicle without disabling or turning this switch off may cause damage to the air suspension system. Spraying the suspected area with soapy water helps detect any leaks in the system.

Answer D is wrong. Both technicians are correct.

9. Loose tie rods are discovered during the initial inspection of a vehicle's steering linkage. Technician A says loose tie rods will cause a clunking or popping noise while turning. Technician B says loose tie rods will result in constant steering correction and vehicle wander. Who is correct?

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

9.

Answer A is wrong. Both of these technicians are correct. Loose tie rods make a clunking or popping sound when the wheel is turned and cause a vehicle to wander.

Answer B is wrong. As the vehicle travels down the road, the steering wheel will require correction from left to right to compensate for the loose steering linkage.

Answer C is correct. Both technicians are correct.

Answer D is wrong. Both technicians are correct.

10. Technician A says a directional tire must be kept on the same side of the vehicle during a tire rotation. Technician B says tire inflation pressure is considered cold as long as the vehicle has been driven less than ten miles. Who is correct?

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

10.

Answer A is correct. Directional tires have arrows pointing toward the front of the vehicle and must be installed accordingly. Directional tires can only be rotated front to rear and should not be crossed from side to side.

Answer B is wrong. A tire is considered cold when driven less than three miles.

Answer C is wrong. Technician A is correct.

Answer D is wrong. Technician A is correct.
