to terminals 1 and 2 of instrument speaker LH and RH.
When one of audio steering wheel switch is pushed to volume up, seek up, or mode ON, resistance in steering
switch circuit changes depending on which button is pushed.
When one of audio steering wheel switch is pushed to volume down, seek down, or power ON, resistance in
audio steering wheel switch circuit changes depending on which button is pushed.
BOSE SYSTEM
Refer to Owner's Manual for audio system operating instructions.

A/C and AV Switch Self-Diagnosis FunctionAKS00BMP
It can check ON/OFF operation of each switch in the A/C and AV switch and diagnose the input signals to the
audio steering wheel switch.
STARTING THE SELF-DIAGNOSIS MODE
1. Turn ignition switch from OFF to ACC.
2. Within 10 seconds press and hold the switches “MUTE/II ” and
“PREV ” simultaneously for 3 seconds.
DIAGNOSIS FUNCTION
The following are checked:
All the indicators (LED) in the A/C and AV switch.
Continuity of the switches by sounding the buzzer when the A/C and AV switch is pressed.
Continuity of harness between A/C and AV switch and audio steering wheel switch.
EXITING THE SELF-DIAGNOSIS MODE
Turn ignition switch OFF.
Trouble DiagnosisAKS00BMQ
The majority of the audio malfunctions are the result of outside causes (bad CD/cassette, electromagnetic
interference, etc.). Check the symptoms below to diagnose the malfunction.
MALFUNCTION WITH RADIO, TAPE AND CD (BASE SYSTEM)
Make sure that operation excepting audio system can be done with A/C and AV switch. If not, refer AV- 8 4 , "A/
C and AV Switch Does Not Operate" to repair malfunctioning parts.

FOR RADIO ONLY
NOTE:
This is noise resulting from variations in field strength, such as fading noise and multi-path noise, or external
noise from trains and other sources. It is not a malfunction.
Fading noise: This noise occurs because of variations in the field strength in a narrow range due to moun-
tains or buildings blocking the signal.
Multi-path noise: This noise results from the waves sent directly from the broadcast station arriving at the
antenna at a different time from the waves which reflect off of mountains or buildings.

Noise InspectionAKS00BMR
The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunction.
Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and opera-
tion of each piece of electrical equipment, and determine the cause.
NOTE:
The source of the noise can be found easily by listening to the noise while removing the fuses of electrical
components, one by one.
TYPE OF NOISE AND POSSIBLE CAUSE
Occurrence condition Possible cause
Occurs only when engine is
ON.A continuous growling noise occurs. The speed
of the noise varies with changes in the engine
speed.
Ignition condenser
A whistling noise occurs while the engine speed
is high. A booming noise occurs while the engine
is running and the lighting switch is ON.
Alternator
The occurrence of the noise is linked with the operation of the fuel pump.
Fuel pump condenser
Noise only occurs when various
electrical components are oper-
ating.A cracking or snapping sound occurs with the
operation of various switches.
Relay malfunction, radio malfunction
The noise occurs when various motors are oper-
ating.
Motor case ground
Motor
The noise occurs constantly, not just under certain conditions.
Rear window defogger coil malfunction
Open circuit in printed heater
Poor ground of antenna amplifier or
antenna feeder line
Mirror type film is attached on the rear win-
dow glass
After-market TV antenna and/or electrical
accessories such as radio are attached on
the rear window glass.
A cracking or snapping sound occurs while the vehicle is being driven, especially
when it is vibrating excessively.
Ground wire of body parts.
Ground due to incorrectinstallation of
parts.
Wiring connections or ashort circuit.
