Two horns are fitted to the vehicle; a high tone and a low tone.
The horns are mounted on brackets, which are attached to the front end carrier
assembly, on each side of the radiator.
The horns are operated by
pressing one of the two horn switches, located on each side of the driver
airbag, on the steering wheel.
The horns are also used by the vehicle
alarm system. When the alarm system requires the horns to operate, the Central
Junction Box (CJB) provides a ground to the horn relay solenoid, closing the
relay contact which in turn supplies battery voltage to operate the horns.
Anti-Theft - Active (419-01A Anti-Theft -
Active)
The horn circuit is permanently connected to battery voltage
and therefore the horns can be operated at any time, irrespective of ignition
switch position.
The horns are controlled by a relay which is an integral
part of the CJB. The relay contact and solenoid is connected to the vehicle
battery via a fusible link (Link 17) in the battery junction box and a fuse
(F12) in the CJB. The horn switches, when pressed, complete a ground to the
relay which energises the solenoid. The energised solenoid closes the relay
contact and battery voltage is supplied to each of the horns. When the horn
switch is released, the ground for the solenoid is broken, the solenoid is
de-energised and the relay contact opens, cutting the voltage supply to the
horns.
