ACCS (ADVANCED CLIMATE CONTROL SYSTEM) : System Description

INFOID:0000000009652524

SYSTEM DIAGRAM

DESCRIPTION

ACCS (advanced climate control system) controls passenger room air. It maintains the cleanliness of the pas-
senger room air using a high performance filter and a combination of each of the following functions.
• Automatic intake control (exhaust gas/outside odor detecting mechanism)
• Plasmacluster

 ion

NOTE:
• Plasmacluster

 ion technology developed by Sharp Corporation is installed in this item.

• Plasmacluster

 is a trademark of Sharp Corporation.

AUTOMATIC INTAKE CONTROL (EXHAUST GAS/OUTSIDE ODOR DETECTING MECHANISM)

Description

In addition to air inlet automatic control of front automatic air conditioning system, A/C auto amp. controls
automatically air inlet according to signal from exhaust gas/outside odor detecting sensor, so that exhaust gas
and unpleasant outside odor does not enter in passenger room. 

Operation Description

• When AUTO intake switch is pressed while front blower motor is activated, AUTO intake indicator and REC

indicator turn ON. Air inlet is fixed to recirculation for approximately 5 minutes, and then is switched to auto-
matic intake control (exhaust gas/outside odor detecting mechanism).

• Air inlet switches to recirculation when ambient atmospheric CO,

NO

2

 and unpleasant odor is detected while automatic intake con-

trol (exhaust gas/outside odor detecting mechanism) is operated.
After that, air inlet switches to fresh air intake when exhaust gas
and unpleasant outside odor becomes not detectable.

• When the AUTO intake switch is turned ON, ambient atmosphere

status is indicated on the display in the front A/C control according
to the signal from the exhaust gas/outside odor detecting sensor.
Refer to 

HAC-44, "ACCS (ADVANCED CLIMATE CONTROL SYS-

TEM) : Switch Name and Function"

.

NOTE:
• Sensitivity of exhaust gas/outside odor detecting sensor can be

changed. Refer to 

HAC-85, "Exhaust Gas/Outside Odor Detecting Sensor Sensitivity Adjustment Function"

.

• Automatic intake control (exhaust gas/outside odor detecting mechanism) does not operate when air outlet

is D/F, DEF mode or ambient temperature is 0

°

C (32

°

F) or less. In this case, control is only for control of

automatic air inlet of automatic air conditioning system.
