A/C and AV Switch Self-Diagnosis Function

AKS005RI

Performing self-diagnosis makes it possible to check operation of A/C and AV switch indicator (LED) and other
switch.

STARTING THE SELF-DIAGNOSIS MODE

1.

Turn ignition switch from OFF to ACC.

2.

Within 10 seconds press 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 pressed.

●

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

NOTE:

●

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

→

“REC”

→

“FRE” every time the REC/FRE switch

is pressed. (These two do not turn on at the same 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.

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.
