Functional Tests
Now, check that all controls and systems are functioning correctly. Test
horn, lights, and all other safety equipment and accessories. Be sure
they are properly mounted and working correctly.
Check all wheel lug bolts to be sure
none are loose or missing.
Have missing bolts replaced and
loose bolts tightened to the correct
torque before operating truck.
Press the horn button to check horn
function. If the horn or any other part
does not operate, report the failure,
and have it repaired before the truck
is put into operation (key switch must
be ON to operate the horn).
