Horn Operation
The horn switch uses sets of contacts separated by springs. The lower
set is connected to ground and the upper set is connected to the horn
signal circuit. When the driver airbag is pressed, it pushes down on the
upper set of contacts, collapsing the springs and allowing the contacts
to touch. When the contacts touch, it completes the circuit and
provides a ground signal through the clockspring to the BCM horn input.
The BCM then grounds the integrated horn relay coil in the BCMC
to energize the non-serviceable relay. When energized, the horn relay
provides voltage to the horn, enabling the horn to sound.

Nearly all engines consume oil, which is essential for
normal lubrication of the cylinder bore walls and pistons and rings.
Determining the level of oil consumption may require testing by
recording how much oil is being added over a given set of miles...
