ASE A5 Brakes Practice Test

61. The 40-amp fuse for the ABS/EBCM control module has blown. The work order indicates another technician recently replaced the same fuse. Which of the following is MOST likely causing this fuse to burn?

  • A. A short to ground.
  • B. High resistance in the EBCM connector.
  • C. A faulty wheel speed sensor.
  • D. An open ground circuit.

61.

Answer A is correct. A short to ground will overload the circuit and cause the fuse to blow.

Answer B is wrong. If the circuit's fuse continues to blow, inspect the harness and wiring for damaged insulation.

Answer C is wrong. Technician A is correct.

Answer D is wrong. Technician A is correct.

62. The motor generator of a hybrid passenger car propels the vehicle and charges the battery. Technician A says the vehicle has a regenerative braking system. Technician B says this vehicle's brake pads and rotors tend to wear and may require more frequent replacement. Who is correct?

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

62.

Answer A is correct. Hybrid and electric vehicles use regenerative braking systems that create electricity while braking.

Answer B is wrong. Because regenerative braking does much of the stopping, there is less wear on the vehicle's conventional friction brake system.

Answer C is wrong.Technician A is correct.

Answer D is wrong. Technician A is correct.

63. A vehicle with an automatic transmission will not shift out of PARK with the engine running and the brake pedal depressed. Technician A says a faulty stop light fuse will result in this condition. Technician B says a defective brake light switch will cause this condition. Who is correct?

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

63.

Answer A is wrong. A blown brake light fuse or a faulty brake switch will result in no brake lights.

Answer B is wrong. A modern transmission requires the voltage signal from the brake switch to operate the shift interlock solenoid.

Answer C is correct. Both Technicians are correct. The brake lights, push-button ignition, shift interlock, cruise control, and ABS/TCS require the brake switch signal to function properly.

Answer D is wrong. Both Technicians are correct. Learn more about brake light switches by clicking the Read More button.

Parking Brake Circuit

64. The parking brake warning light in the diagram is continuously illuminated. Which of these is MOST likely the cause?

  • A. A short to ground at point C of the diagram.
  • B. An open at point D of the diagram.
  • C. High Resistance at point A of the diagram.
  • D. A short to ground at point B of the diagram.

64.

Answer A is correct. A short to ground after the bulb in a ground controlled circuit will illuminate the bulb.

Answer B is wrong. An open in the ground will prevent the light from illuminating.

Answer C is wrong. High resistance in the circuit would likely make the light dim or possibly not functional at all.

Answer D is wrong. A short to ground before the bulb would likely leave the bulb not illuminated at all. A short to ground in a circuit will likely blow the fuse.

65. The red brake warning light on the instrument panel illuminates when the brakes are applied. Which of the following results in this condition?

  • A. A burned brake light bulb.
  • B. Air in the hydraulic brake system.
  • C. A damaged wheel speed sensor tone ring.
  • D. An open in the brake switch circuit.

65.

Answer A is wrong. Some vehicles have a brake light failure indicator. This is typically amber. A burned brake light bulb will not illuminate the red brake warning light.

Answer B is correct. The red brake warning light will illuminate if there's a loss in pressure in one of the two hydraulic brake circuits if the parking brake is engaged or if the key is in the ON/RUN position.

Answer C is wrong. If the ABS controller senses a damaged tone ring by an erratic wheel speed sensor signal, it will illuminate the amber ABS light.

Answer D is wrong. The brake lights would not illuminate if the brake switch has an open circuit.
