Horn Switch: Testing and Inspection

The horn contact consists of,
- A contact switch is mounted between the Driver Airbag Module and steering wheel
- The horn wire is attached to Driver Airbag Module 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 carried to the horn relay and horn sounds.

Horn Contact - Typical:

1. Ground horn wire.
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.
