A/C and AV Switch Self-Diagnosis Function

AKS005RI

It can check ON/OFF operation of each switch in the A/C and AV switch and diagnose the input signals to the
steering switch.

STARTING THE SELF-DIAGNOSIS MODE

1.

Turn ignition switch from OFF to ACC.

2.

Within 10 seconds push and hold the switches “PAUSE/MUTE”
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 pushed.

Continuity of harness between A/C and AV switch and steering switch.

NOTE:

Indicators (LED) of REC/FRE switch change to “FRE”

“REC”

“FRE” every time the REC/FRE switch is

pushed. (These two do not turn on at a time.)

Impossible to check rear window defogger switch operation (No beep sound even under normal status).

EXITING THE SELF-DIAGNOSIS MODE

Turn ignition switch OFF.

Trouble Diagnosis

AKS005F2

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 AND CD (BASE SYSTEM)

Make sure that other operation except audio system can be performed with A/C and AV switch. If these oper-
ations are inoperative with A/C and AV switch, refer to 

AV-100, "A/C and AV Switch Does Not Operate"

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 Inspection

AKS005F3

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

Check item

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 operat-
