A/C and AV Switch Self-Diagnosis FunctionAKS007OE
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
“MAP ”simultaneously for 3 seconds.
Then the self-diagnosis operates.
EXITING THE SELF-DIAGNOSIS MODE

Turn ignition switch OFF. Then the self-diagnosis ends.
DIAGNOSIS FUNCTION

It can illuminate all the indicators (LED) in the A/C and AV switch.

It can check for continuity of the switches by sounding the buzzer when the A/C and AV switch is pressed.

It can check for continuity of harness between A/C and AV switch and audio steering wheel switch.
