General description

GENERAL DESCRIPTION

The car horn system is formed of two horns with different tones: one high tone and the other low tone: they are both activated simultaneously.

The horns are operated conventionally pressing the button located in the centre of the steering wheel (versions without airbag) or one of the two switches on the spokes at the side of the airbag cushion (versions with airbag).

For the obvious safety reasons the horns can be activated at all times even if the ignition key is not engaged.

FUNCTIONAL DESCRIPTION

The horns relay switch I3, located in fusebox G1, is supplied by the battery through fuse F2, also in G1.

The coil of relay switch I3 is energized with an earth signal leading from the horn control switch which is connected to the lever unit B68 (this connection is made in a special way for the versions with airbag: see "Checking Components").

This way the supply is sent by the relay switch to the horns O2, which are already connected to earth.
