What should a technician enter if the air pump drive belt has been removed from the vehicle?

• A. Enter the AIR system as 'Not Present'.
• B. Leave the AIR system entry blank.
• C. Enter the AIR system as 'Missing'.
• D. Enter the AIR system as 'Removed'.

Answer: (C)

When documenting the AIR system, you reflect the actual status of its components. If the air pump is still mounted but its drive belt has been removed, the correct entry is that the system is Missing. This communicates that a part needed for the system to operate—the belt—is absent, so the pump cannot run. Not Present would mean the whole AIR system isn’t installed at all, which isn’t the case here. Leaving the entry blank would fail to show the issue, and Removed would imply the pump or system itself was taken out. So, Missing appropriately captures that only a component (the belt) is missing.
