Mode 2 is an easy way to identify a problem circuit
without having to test 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)
1. From mode 1, disconnect the special tool from the
multiplex control system (MPCS) inspection
connector for between 5 and 10 seconds, then
reconnect it. The ignition key light should come on
and the beeper should beep for 2 seconds, then
blink/beep twice more at 0.2 second intervals. This
indicates the system has entered mode 2.
2. Operate the switch as described in the charts below.
NOTE: Key cylinder switch tests require a second
key be used to perform.

Turn the key two

prevent inputs from

causing false input
confirmations.
This input cannot be

test.
