CIRCUIT - SYSTEM SCHEMATIC DIAGRAM 61-83
System description:
The battery current is output from the fuses F28 and F19 in the engine compartment fuse
box to the pins 1 and 3 of the horn relay R13; after passing through the horn relay R13
coil, it is output from the pin 2 to the pin D18 of the engine electronic control module, and 61
then from the pin D5 to the horn switch through the clock spring. When the horn switch is
pressed, the horn switch is earthed, the signal is output from the pin D18 form the engine
electronic control module, and the horn relay R13 coil is electrified to generate a magnetic
field to close the horn relay R13; thus the current is output from the pin 5 through the horn
relay R13 contact to the pin 1 of high-tone horn and the pin 1 of low-tone horn, and then
earthed after passing through the coil in the horn, to activate the horn.
