AV Switch Self-Diagnosis Function

EKS00G5J

It can check ON/OFF operation of each switch in the AV switch (with NAVI) or audio unit (without NAVI) and
diagnose the input signals from the steering switch.

STARTING THE SELF-DIAGNOSIS MODE (EXCEPT BOSE SYSTEM WITH NAVI)

1.

Turn ignition switch from OFF to ACC.

2.

Press and hold the “CLOCK” switch and turn the volume control dial clockwise or counterclockwise for 30
clicks or more.

Then the self-diagnosis operates. A single beep indicates self-diagnosis mode is active.

3.

Initially, all display segments will be illuminated.

4.

Press each switch. When each switch is pressed, its name and communication code will be displayed.
NOTE:
CD player LOAD and EJECT buttons are not included in this test and will not change the display when
pressed.

STARTING THE SELF-DIAGNOSIS MODE (BOSE SYSTEM WITH NAVI)

1.

Turn ignition switch from OFF to ACC.

2.

Within 10 seconds press and hold the switches “PAUSE/MUTE”
and SCAN" 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.

DIAGNOSIS FUNCTION 

●

It can check for continuity of the switches by sounding the beep when each AV switch and steering switch
is pressed.

●

It can check for continuity of harness between AV switch and steering switch.

Trouble Diagnosis

EKS00G5K

The majority of the audio troubles are the result of outside causes (bad CD, electromagnetic interference,
etc.). Check the inspection items below to diagnose the malfunction.
