Horn - Description

DESCRIPTION

The horn system features one low-note horn unit. The horn system uses a non-switched source of battery current so that the system will remain functional, regardless of the ignition switch position. The horn system includes the following components:

- Horn - The horn is located in the engine bay directly behind the left head lamp.
- Horn fuse - The horn fuse is located in the Total Integrated Power Module (TIPM).
- Horn switch - The horn switch is located under the driver airbag assembly.

On vehicles with an optional Electronic Vehicle Information Center (EVIC), the horn switch shares the same circuit as the right EVIC switch. This switch is also a LIN bus slave, sharing a LIN input circuit to the CCN (LIN master) with the Steering Control Module (SCM), which is also a LIN bus slave. The right EVIC switch also shares an IOD feed and a ground feed in common with the SCM.
Vehicles with an optional EVIC and steering wheel mounted switches (except LX) have a unique horn switch electrical architecture. For more information on the EVIC Electronic Vehicle Information Center - Description.
