AUDIOPFP:28111
System DescriptionEKS00INI
WITH CASETTE DECK
Refer to Owner's Manual for audio system operating instructions.
Power is supplied at all times

through 15A fuse [No. 32, located in the fuse and fusible link box]

to audio unit terminal 6.
With the ignition switch in the ACC or ON position, power is supplied

through 10A fuse [No. 4, located in the fuse block (J/B)]

to audio unit terminal 10.
When audio switch is pushed, audio signals are supplied

through audio unit terminals 1, 2, 3, 4, 13, 14, 15, and 16

to terminals 1 and 2 of Front door speaker LH and RH

to terminals 1 and 2 of Rear speaker LH and RH

to terminals 1 and 2 of tweeter LH and RH.
When one of audio steering wheel switches is pushed to volume up, seek up, or source, resistance in steering
switch circuit changes depending on which button is pushed. This will change voltage. Power is supplied

from audio unit terminal 26

through combination switch (spiral cable) terminal 4 and 13

to audio steering wheel switch terminal 3.
Ground is supplied

from audio steering wheel switch

through combination switch (spiral cable) terminal 15 and 7

to audio unit terminal 29.
When one of audio steering wheel switches is pushed to volume down, seek down, or special, resistance in
steering switch circuit changes depending on which button is pushed. This will change voltage. Power is sup-
plied

from audio unit terminal 27

through combination switch (spiral cable) terminal 5 and 14

to audio steering wheel switch terminal 4.
Ground is supplied

from audio steering wheel switch

through combination switch (spiral cable) terminal 15 and 7
