AV Switch Self-Diagnosis FunctionEKS00BIF
It can check ON/OFF operation of each switch in the AV switch and diagnose the input signals from the steer-
ing switch.
STARTING THE SELF-DIAGNOSIS MODE
1. Turn ignition switch from OFF to ACC.
2. Within 10 seconds press and hold the switches “MEMORY 1”
and “MEMORY 6 ” simultaneously for 3 seconds.
Then the self-diagnosis operates. A single beep indicates self-
diagnosis mode is active.
3. Press each switch and listen for beep. NOTE:
CD player LOAD and EJECT buttons are not included in this test
and will not beep when pressed.
EXITING THE SELF-DIAGNOSIS MODE
Turn ignition switch OFF. Then the self-diagnosis ends.

NOTE:
1. The following noise results 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 mountains or buildings.
FOR CD ONLY
FOR SATELLITE RADIO TUNER (FACTORY INSTALLED) ONLY
NOTE:
Pressing the SAT button, the display unit will display `NO SAT' when the following conditions exist:

Loss of power to the satellite radio tuner (factory installed)

Open or short in the REQ1, TXD, or RXD circuits.
If the satellite antenna is disconnected or inoperative, the display unit will display ANTENNA.
Noise InspectionEKS00BIH
The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning.
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.
