8G - 2 HORNS

DIAGNOSIS AND TESTING

HORN

(1) Disconnect wire connector at horn.
(2) Using a voltmeter, connect one lead to ground
terminal and the other lead to the horn relay output
wire terminal (Fig. 1).
(3) Depress the horn switch, battery voltage
should be present.
(4) If no voltage, refer to Horn Does Not Sound. If
voltage is OK, go to Step 5.
(5) Using ohmmeter, test ground wire for continu-
ity to ground.
(6) If no ground repair as necessary.
(7) If wires test OK and horn does not sound,
replace horn.

HORN CONTACT SWITCH

The horn contact consist of,
• A contact switch is mounted between the Driver
Airbag Module and steering wheel
• The horn wire is attached to Driver Airbag Mod-
ule mounting bracket.
• When the Driver Airbag Module is pressed the
contact ring touches the bracket mounting bolts and
makes contact to ground. The ground signal is car-
ried to the horn relay and horn sounds.
CIRCUIT NAME
(1) Ground horn wire (Fig. 2).
(2) If horn does not sound, check for corrosion on
wire, bracket or airbag contact ring and ensure horn
wire is properly connected.
(3) If bracket needs to be replaced, the steering
wheel must be replaced. If contact ring is bad the
Driver Airbag Module must be replaced.
(4) Refer to Group 8W, Wiring Diagrams if wire
circuit needs to be repaired.

HORN RELAY

(1) Remove horn relay from the Junction Block
(Fig. 3).

(2) Using ohmmeter, test between the Junction
Block relay terminal 7 and ground for continuity.
