ASE G1 Maintenance & Lt. Repair Practice Test

6. A vehicle's engine is slow cranking. The 12-volt battery passes all tests and is in good condition. Which of the following should the technician test next?

  • A. The starter motor.
  • B. The starter circuit.
  • C. The battery state of charge.
  • D. The charging system.


Answer A is wrong. Perform a voltage drop test to find excessive resistance in a circuit. Voltage drop is the voltage dropped or "lost" as it passes through a component or resistance in a circuit.

Answer B is correct. A slow cranking engine is often caused by resistance in the circuit, usually a loose or corroded battery terminal or connection. A visual inspection and a voltage drop test are the best way to find resistance in a starter circuit.

Answer C is wrong. The battery in this question has passed all tests and is in good condition.

Answer D is wrong. Voltage must be present in the circuit to perform this test. Use a voltmeter at different points in the circuit.

Suspension components.

7. View the illustration above and choose the correct answer below.

  • A. The item in the illustration protects suspension components from metal to metal contact.
  • B. The items in the illustration fit over strut inserts.
  • C. Both A and B are correct.
  • D. Neither A or B is correct.


Answer A is wrong. Jounce bumpers and bump stops absorb the sudden impact that occurs when a vehicle bottoms out.

Answer B is wrong. Two symptoms of missing and worn bump stops include noise and vibration. They’re caused by the metal to metal contact while carrying a load or hitting bumps and potholes in the road.

Answer C is correct. They’re hard foam and rubber parts that perform the same function but come in different shapes and sizes.

Answer D is wrong. Learn more about jounce bumpers by clicking the Read more… button below.

8. A technician is unable to balance a tire on a vehicle that vibrates at speeds above 40 mph. Each time the tire is spun, a weight must be added to a different location on the rim. Which of the following is MOST likely causing this condition?

  • A. The tire's belt is separated.
  • B. There is liquid inside the tire.
  • C. The TPMS sensor is shifting.
  • D. The tire's tread is cupped.


Answer A is wrong. The tire most likely has liquid or something inside. Each time the technician spins the tire, the liquid settles in a different place, and a weight must be added to a different location on the rim. The technician should not just keep adding weights.

Answer B is correct. Dismount the tire and inspect the inside of the tire and rim. Inspect the TPMS sensor; it can become clogged and malfunction, resulting in a TPMS warning light.

Answer C is wrong. Today's direct TPMS systems contain a sensor located in each wheel and sometimes the spare.

Answer D is wrong. The tire must be dismounted to verify this condition. Unbalanced tires cause a vibration that increases with vehicle speed.

9. There is a clunking and popping sound coming from the front of a vehicle that only occurs when turning. Which of the following is causing this condition?

  • A. Loose rod ends.
  • B. A faulty power steering pump.
  • C. Weak coil springs.
  • D. Worn brake pads.


Answer A is correct. Loose tie rods cause a clunking or popping sound when taking turns. They result in wander, requiring constant correction from left to right to compensate for the loose steering linkage.

Answer B is wrong. A faulty power steering pump makes a whining or growling sound when taking turns.

Answer C is wrong. Sagging and weak coils affect the vehicle's ride height. Vehicle riding height or ground clearance is a vital measurement that should be checked before performing a wheel alignment. It affects the toe, caster, and camber angles. Measurements are taken with a tape measure or special tool from the ground to the fender well, bumper, or control arm.

Answer D is wrong. Worn brake pads should be replaced and can result in a loud squeal when the pads metal plate contacts the rotor.

10. A FWD vehicle drifts to the left at all speeds. Technician A says a misaligned engine cradle results in this condition. Technician B says loose motor mounts result in this drift. Who is correct?

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


Misaligned engine cradle can cause a vehicles steering to pull.

Answer A is correct. A misaligned or loose engine cradle affects a FWD vehicle's wheel alignment angles. The engine cradle has the lower control arms attached. Inspect the cradle for damage or excessive wear, especially the lower control arm bushings.

Answer B is wrong. Engine mounts insulate and prevent engine vibrations from transferring to the passenger compartment. This is one of the most common causes of passenger compartment noise and vibration; this is especially true in front wheel drive vehicles.

Answer C is wrong. A crooked or misaligned engine cradle affects the camber. A vehicle pulls to the side with the most positive (+) camber.

Answer D is wrong. Technician A is correct.
