WARNING: This page is about a different car, the 2011 Nissan 370Z. However, it is still accessible from the selected car via links, so may be relevant.

The ON/OFF operation (continuity) of each switch in the multifunction switch and preset switch can be checked.

Press the "BACK" switch and the "UP" switch of the 8-direction switches within 10 seconds after turning the ignition switch from OFF to ACC and hold them for 3 seconds or more. Then the buzzer sounds, all indicators of the preset switch illuminate, and the self-diagnosis mode starts.
The continuity of each switch at the ON position can be checked by pressing the switch. The buzzer sounds if the switch is normal.
