11.11.7.4 Woven leading wire repair of rear windscreen glass defrost 

Notes: 

The rear windshield defroster bus lead 
or terminal can be reconnected 
through re-brazing. Weld through a 
welding rod containing 3% of silver 
and rosin. 

1.  Before welding lead line of CAN, 

it is necessary to clean repair 
position to bright condition with 
fine steel wire. 

2.  Apply a little amount of resin to 

repair positions of lead wire and 
CAN line by using brush. 

3.  Use soldering iron to dip welding 

material enough to ensure repair 
use.

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.
