  • 4. 
    When testing an electric window fault it appears that battery voltage is being recieved at both sides of the motor, is this correct or incorrect?
    • A. 

      Incorrect as the motor would burn out

    • B. 

      Correct, as one of the voltages will change when operated

    • C. 

      Correct as both of the voltages would drop to zero when operated

    • D. 

      Incorrect, as the motor requires a difference in voltages to operate

  • 5. 
    When related to multiplexed systems which is the most accurate statement?
    • A. 

      A traditionally wired electrical systems seding and recieving signals to remote control units

    • B. 

      A traditionally wired electrical system incorporating electronic components

    • C. 

      A data bus system recieving signals from remote control units

    • D. 

      A data bus system carrying signals to and from remote control units

  • 6. 
    If a GPS unit fails to locate a vehicle posistion what is the most likely fault? 
    • A. 

      The system has not located the satelittes yet and would continue to send and recieve signals until an exact location is achieved.

    • B. 

      The system needs a minimum of four satelittes in view to operate

    • C. 

      The system needs an input from various sensors on the vehicle to pin point location

    • D. 

      Only two satellites are in view of the reciever

  • 7.

  • 8. 
    If a leak in an air conditioning system was present what would you expect to happen?
    • A. 

      The TXV Valve would prevent refrigerant flow

    • B. 

      The system would operate normally unit the gas had been exhausted

    • C. 

      The compessor would have its drive disconnected due to low level refrigerant

    • D. 

      The system would regulate the refrigerant flow for optimum performance

  • 9. 
    If an open circuit within the earth circuit was identified on an electric window what would be the most likely outcome
    • A. 

      The window would not go down

    • B. 

      The window would not operate at all

    • C. 

      The window would go down but not go back up

    • D. 

      The window would operate normally as it has a switched earth
