A/C Operation Check Mode
• The front climate control unit forces operation of output related moving parts as indicated in the operation check
table regardless of input related parts, while simultaneously changing the display on the information display as
well as illuminating each switch indicator light automatically. A malfunctioning part can be determined by
verifying that each transition is as indicated in the operation check table through visual inspection, listening to
the operation sound, or placing a hand on the air vent.
