Horn Relay: Testing and Inspection
1. Remove horn relay
2. Using ohmmeter, test between relay connector terminals 85 to 86 for 70 to 80 ohms resistance. If resistance not OK, replace relay. If OK, go to
3. Test for continuity between ground and terminal 85 of horn relay.
a. When the horn switch is not depressed, no continuity should be present.
4. Using voltmeter, check battery voltage at:
a. Terminals 30 and 86 of the horn relay to body ground.
5. Insert a jumper wire between terminal 30 and 87 of the Power Distribution Center.
a. If horn sounds, replace relay
Horns Will Not Sound
System. If voltage is OK, on one side of fuse, the fuse is blown, replace fuse and try horns again. If fuse blows go to Fuse Blown.
necessary. If no continuity go to Step 3.
3. Check for continuity to ground at cavity 5 of the relay connector. If continuity to ground there is a short to ground repair as necessary If no
continuity, connect the wire connectors to the horns and go to Horn Relay Test.
Horns Sound Continuously
CAUTION: Continuous sounding of horns may cause relay and horn to tail.
The horn switch (membrane) sometimes can be the cause without the switch being depressed.
a. If continuity is detected, proceed to Step 3.
3. Remove the Driver's Airbag Module from the steering wheel and disconnect the horn connector.
a. If horn does not sound, replace Driver's Airbag Module.
