Horn Relay: Description and Operation
SYSTEM OPERATION
The horn relay is a International Standards Organization (ISO) micro-relay The terminal designations and functions are the same as a conventional
ISO relay. However, the micro-relay terminal orientation (or footprint) is different, current capacity is lower, and the relay case dimensions are
smaller than on the conventional ISO relay.
The horn relay is a electromechanical device that switches current to the horn when the horn switch on the steering wheel is depressed.
The horn relay is located in the Power Distribution Center (PDC), in the engine compartment. Refer to the PDC label for horn relay identification
and location.
If a problem is encountered with a continuously sounding horn, it can usually be quickly resolved by removing the horn relay from the PDC until
further diagnosis is completed. The horn relay cannot be repaired and, if faulty, it must be replaced.
The horn relay is a electromechanical device that switches current to the horn when the horn switch or the high-line Central Timer Module (CTM)
grounds the relay coil. The horn relay is located in the Power Distribution Center, in the engine compartment.
