DESCRIPTION
The dual-note horn system features two electromagnetic horn units. The horn system includes the following major components
- Horn - The two horns are located on the right side of the engine compartment near the right side headlamp.
- Horn Switch - The horn switch is located in the driver airbag cushion pocket, under the airbag trim cover.
OPERATION
The horn system operates on battery current received through a fuse in the Integrated Power Module (IPM). The horn system circuit is designed so that the system will remain operational, regardless of the ignition switch position.
Any diagnosis of the Horn system should begin with the use of the DRB III(R) diagnostic tool. For information on the use of the DRB III(R), refer to BODY DIAGNOSTIC PROCEDURES .
For complete circuit diagrams, refer to SYSTEM WIRING DIAGRAMS .
In most cases, any problem involving continually sounding horns can be quickly alleviated by removing the horn fuse from the Integrated Power Module (IPM).
Note. For additional information on airbag system, refer to RESTRAINTS .
| 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. |
