DITIONER SYSTEM : CONSULT-III Function" (WITH INTELLIGENT AIR CONDITIONER SYSTEM).
NOTE:
Perform the ACTIVE TEST after starting the engine because the compressor is operated.
2. Refer to the table and check the outlet, inlet, air flow temperature, blower motor control signal, magnet
clutch operation, and air mix ratio. Visually check each operating condition, by listening for noise, touching
air outlets with a hand, etc.
NOTE:
 Perform the inspection of each output device after starting the engine because the compressor is oper-
ated.
 When choosing to “MODE 7”, error message is displayed but it is not malfunction.
