Standard Horn

Horn System:

WARNING: ON VEHICLES EQUIPPED WITH AIR- BAG. DISCONNECT THE NEGATIVE CABLE FROM THE BATTERY BEFORE SERVICING COMPONENTS INVOLVING THE AIRBAG SYSTEM. ACCIDENTAL DEPLOYMENT OF AIRBAG AND PERSONAL INJURY CAN RESULT.

The horn circuit consists of a horn switch, clock-spring, horn relay, horns and Body Control Module. The horn switch is a membrane switch located in the airbag cover. The horns are located forward of the left front wheel behind the bumper fascia. The horn relay plugs into the junction block.

CIRCUIT OPERATION
The horn system is powered by a 20 amp fuse located in cavity 20 of the Power Distribution Center (PDC). The fuse is HOT at all times, on circuit F62, and supplies Voltage to the coil and to the contact side of the horn relay

When the operator presses the horn switch, a ground path is completed on the coil side of the horn relay through the switch, on circuit X3. The horn relay, located in the PDC, then CLOSES the relay contacts. Voltage is passed through the CLOSED relay contacts on circuit X2 to the horns.

Grounding for the horns is on the Z1 circuit to the right cowl panel.

On vehicles equipped with Vehicle Theft Security System (VTSS), the X3 circuit is spliced to the Body Control Module (BCM).
