DESCRIPTION AND OPERATION

HORN SYSTEM

DESCRIPTION

A dual-note electric horn system is standard facto-

ry-installed equipment on this model. The standard
equipment horn system features one low-note horn
unit and one high-note horn unit. The horn system
uses a non-switched source of battery current so that
the system will remain functional, regardless of the
ignition switch position. The horn system includes
the following components:

• Clockspring

• Horns

• Horn relay

• Horn switch

• Remote Keyless Entry (RKE) receiver (only with

the RKE system)

Refer to Clockspring in the Description and Oper-

ation section of Group 8M - Passive Restraint Sys-
tems for more information on this component. Refer
to Remote Keyless Entry System in the Descrip-
tion and Operation section of Group 8P - Power Lock
Systems for more information on this component.
Refer to Horn/Cigar Lighter in the Contents of
Group 8W - Wiring Diagrams for complete circuit
diagrams. Following are general descriptions of the
remaining major components in the horn system.

OPERATION

The horn system is activated by a horn switch con-

cealed beneath the driver side airbag module trim
cover in the center of the steering wheel. Depressing
the center of the driver side airbag module trim cover
closes the horn switch. Closing the horn switch acti-
vates the horn relay. The activated horn relay then
switches the battery current needed to energize the
horns.

Refer to the owner’s manual in the vehicle glove

box for more information on the features, use and
operation of the horn system.

REMOTE KEYLESS ENTRY RECEIVER

The Remote Keyless Entry (RKE) receiver can also

operate the horn system. An RKE receiver is used on
this vehicle when it is equipped with the optional
RKE system. The RKE receiver controls and inte-
grates the additional electronic functions and fea-
tures

included

models

with

this

option. A

customer programmable feature of the RKE system
enables the RKE receiver to momentarily energize
the horn relay through a hard wired circuit as an
audible verification that the receiver has received a
valid lock request from the RKE transmitter.

Refer to Remote Keyless Entry System in the

Description and Operation section of Group 8P -
Power Lock Systems for more information on this
feature.

HORN

DESCRIPTION

The dual electromagnetic diaphragm-type horns

are standard equipment on this model. The low-note
horn is secured with a bracket to the left radiator
closure panel brace, behind the front bumper. The
high-note horn is secured with a bracket to the right
radiator

closure

panel

brace,

behind

the

front

bumper. Both horns are grounded through their
mounting brackets and receives battery feed through
its wire harness connector and circuit from the closed
contacts of the horn relay.

The horns cannot be repaired or adjusted and, if

faulty

damaged,

they

must

individually

replaced.
