The horn system uses a non-switched source of bat- • Clockspring • Horn • Horn relay • Horn switch OPERATION The horn system is activated by a horn switch con- cealed beneath the driver side airbag module trim HORN DESCRIPTION The horn is secured with a bracket to the left front inner fender shield just ahead of the left front wheel The horn cannot be repaired or adjusted and, if faulty or damaged, it must be replaced. OPERATION Within the two halves of the molded plastic horn housing are a flexible diaphragm, a plunger, an elec- is secured in suspension around its perimeter by the mating surfaces of the horn hous- ing. The plunger is secured to the center of the dia- and extends into the center of the electromagnet. The contact points control the current When the horn is energized, electrical current flows through the closed contact points to the electro- DIAGNOSIS AND TESTING - HORN For complete circuit diagrams, refer to the appro- priate wiring information. (1) Disconnect the wire harness connectors from the horn connector receptacles. Measure the resis- (2) Check for battery voltage at the horn relay out- put circuit cavity of the horns wire harness connec- (3) Depress the horn switch. There should now be battery voltage at the horn relay output circuit cavity TJ HORN 8H - 1 |
