Description And Operation: Horn: Notes

There are three separate conditions that can cause the horn to sound. The horn will sound if the driver presses the horn switch(es), when the vehicle security module is armed, or when the tire pressure module (TPM) is in the calibration mode. The horn system uses a horn relay to provide voltage to the horns, while the horn switches, vehicle security module and TPM provide the grounds to engage the horn relay. The horn switch is integrated into the air bag. For the removal and installation of the air bag, refer to DUAL-STAGE DRIVER-SIDE AIR BAG MODULE .

The vehicle security module is located behind the right quarter trim panel. For the removal and installation of the vehicle security module, refer to MODULE COMMUNICATIONS NETWORK .
