11.12.2 Description and operation

11.12.2.1 Description and operation

The horn is arranged in the engine cabin and fixed at the both sides of the radiator at the front of
the vehicle. The high tone horn arranged at the right side and the bass horn arranged at the left side
are controlled by a steering wheel horn switch jointly. When the steering wheel horn button is
pressed down, the horn circuit is electrified, so that the horn makes a sound.

A compound horn is used as anti-theft horn at the same time, which is driven to beep by
controlling the relay grounding through the BCM.

11.12.3 System work principle

11.12.3.1 System operating Principle

The control mode of the horn is to control the power supply end, i.e., the horn switch controls the
closing of the horn relay, then the relay provides supply to the horn; and the horn is normally
grounded. The BCM controls the grounding of the relay and sounding by the horn to achieve an
anti-theft action.
