VM101- Passenger Vehicle Maintenance Course

This is a prototype course for the purpose of creating and extracting xAPI statements to an LRS.  The statements will be used to calculate a student's learning objective performance value.  

(A) Without the aid of reference, recall the major components of a vehicle's hydraulic brake system and their purpose.

Hydraulic Brake System Content

The major components of a vehicle's hydraulic brake system are the brake pedal, pushrod, master cylinder assembly, hydraulic brake lines, and the brake caliper assembly.

The purpose of the hydraulic brake lines is to carry brake fluid from the master cylinder to the brake caliper assembly.

The purpose of the brake pedal is to transfer the driver’s input requesting to slow the speed of a vehicle to a mechanical action by the entire hydraulic brake system.

Which of the following is NOT a major component of a vehicle's hydraulic brake system?

  • brake pedal
  • pushrod
  • hydraulic brake lines
  • steering wheel

Which of the following describes the purpose of the hydraulic lines?

  • carry the windshield wiper fluid
  • carry the brake fluid from the master cylinder to the brake caliper assembly
  • carry the electrical current from the ignition to the starter
  • cpen the vehicle doors

(B) Without the aid of reference, recall the major components of a vehicle's electrical system and their purpose.

Electrical System Module

The major components of a vehicle electrical system are the engine control unit, alternator, battery, starter solenoid, starter, fuse box, ignition switch, and the starter relay. 

The purpose of the alternator is to recharge the battery of the power it uses while the vehicle is running. 

The purpose of the ignition switch is to activate the electrical power of a vehicle. 

The purpose of the battery is to provide the electrical current needed to start the vehicle. 

The purpose the starter solenoid is to convert electrical current to mechanical motion to enable the starter motor to start the vehicle.

Which of the following is NOT a major component of a vehicle's electrical system?

  • fuse box
  • battery
  • tire
  • alternator

Which of the following describes the purpose of the alternator?

  • recharge the battery
  • inflate the tires
  • open the doors
  • cool the engine down

(C) Without the aid of reference, recall the major components of a vehicle's steering system and their purpose.

Steering System Module

The major components of a vehicle steering system are the steering wheel, steering column, power steering pump, powering steering fluid reservoir, tie rods, rack and pinon unit, and tires.

The purpose of the steering column is to connect the steering wheel to the rack and pinon unit to transfer the driver inputs to the remaining steering assembly.

The purpose of the tie rods is to connect the steering assembly to the wheels and ensure the wheels maintain alignment.

The purpose of the power steering pump is to provide the hydraulic fluid pressure needed to operate the power steering system.

The purpose the power steering fluid reservoir is to store hydraulic fluid needed to operate the power steering system.

Which of the following is NOT a major component of a vehicle's steering system?

  • passenger door
  • power steering pump
  • steering wheel
  • steering column

Which of the following describes the purpose of the steering column?

  • transfer driver inputs to remaining steering assembly
  • inflate the tires
  • carry the electrical current from the ignition to the starter
  • cool the engine down

(D) Without the aid of reference, recall the major components of a gasoline engine and their purpose.

Gasoline Engine Module

The major components of a gasoline engine are the crankshaft, camshaft, timing belt, fuel injector, intake manifold, exhaust manifold, cylinder head cover, pistons, engine block, spark plugs, electric coil, distributor, and oil pan.

The purpose of the crankshaft is to convert the up and down motion of the pistons into rotational motion which enable the turning of the drive train.

The purpose of the fuel injector is to provide the proper fuel air mixture to the engine’s combustion chambers to enable movement of the pistons.

Which of the following is NOT a major component of a gasoline engine?

  • exhaust manifold
  • distributor
  • timing belt
  • steering column

Which of the following describes the purpose of the crankshaft?

  • recharge the battery
  • convert the up and down motion of the pistons into rotational motion
  • increase the speed of the vehicle
  • cool the engine down
