Horn System Test (Part 2 Of 2):

Refer to Horn System Test below. If the horn does not sound, check horn fuse located in the intelligent power module. If the fuse is blown, replace with the correct fuse. If the horns fail to sound and the new fuse blows when depressing the horn switch, a short circuit in the horn or the horn wiring between the fuse terminal and the horn is responsible, or a defective horn switch allowed the horn to burn out is responsible.

If the fuse is OK, test horn relay (Refer to HORN RELAY - DIAGNOSIS AND TESTING).

If the relay is OK, test horn. Refer to Horn System Test.

CAUTION: Continuous sounding of horn may cause horn relay to fail.

Should the horn sound continuously:
- Unplug the horn relay from intelligent power module.
- Refer to (Refer to HORN RELAY - DIAGNOSIS AND TESTING).
