WARNING: This page is about a different car, the 2006 Acura MDX, 2005 Acura MDX, 2004 Acura MDX, and 2003 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.

Mode 2 is an easy way to identify a problem circuit with out having to test the circuit with a DVOM. Mode 2 will confirm a switch/circuit is working by flashing the ignition key light and sounding the beeper as the circuit is used. The multiplex control system will confirm inputs as they are grounded except for the following circuits:

Turning the intermittent wiper ring (several confirmations as ring is turned).
Turning the dash light illumination dimmer (several confirmations as the knob is turned).
The Audio unit, Navigation display, RES display, DVD player (confirmation as any one component is disconnected).
