Horn Switch: Testing and Inspection
HORN SWITCH
The most reliable, efficient, and accurate means to diagnose the horn system requires the use of a scan tool and the proper Diagnostic
Procedures information.
For complete circuit diagrams, refer to the appropriate wiring information.
WARNING: Disable the airbag system before attempting any steering wheel, steering column, seat belt tensioner, side airbag, or instrument
panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the airbag system
capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to take the
proper precautions could result in accidental airbag deployment and possible personal injury.
