°C (90°F) by operating the temperature control dial.

2. Press OFF switch.

3. Turn ignition switch OFF.

4. Turn ignition switch ON.

5. Press AUTO switch.

6. Check that set temperature is maintained.
Is the inspection result normal?

YES

>> GO TO 2.

NO

>> GO TO 10.

2.

CHECK AIR FLOW

1. Start engine.

2. Operate fan control dial.

3. Check that air flow changes. Check operation for all fan speeds.
Is the inspection result normal?

YES

>> GO TO 3.

NO

>> GO TO 10.

3.

CHECK AIR OUTLET

1. Operate fan control dial to set the fan speed to maximum speed.

2. Operate MODE switch and DEF switch.

3. Check that air outlets change according to each indicated air outlet by placing a hand in front of the air

outlets. Refer to

VTL-5, "System Description"

.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> GO TO 10.

4.

CHECK AIR INLET

1. Press intake switch to set the air inlet to recirculation. [Intake switch indicator (

side) turns ON.]

2. Listen to intake sound and confirm air inlets change.
3. Press intake switch again to set the air inlet to fresh air intake. [Intake switch indicator (

side) turns

OFF and (

side) turns ON.]

4. Listen to intake sound and confirm air inlets change.
Is the inspection result normal?

YES

>> GO TO 5.

NO

>> GO TO 10.

5.

CHECK COMPRESSOR

4. Check that compressor stops.
Is the inspection result normal?

YES

>> GO TO 6.

NO

>> GO TO 10.

6.

CHECK DISCHARGE AIR TEMPERATURE

1. Operate temperature control dial.

2. Check that discharge air temperature changes.

Check condition : Engine running at normal operating temperature.

CHECK TEMPERATURE DECREASE

1. Operate compressor.

2. Operate temperature control dial and lower the set temperature to 18

°C (60°F).

3. Check that cool air blows from the air outlets.
Is the inspection result normal?

YES

>> GO TO 8.

NO

>> GO TO 10.

8.

CHECK TEMPERATURE INCREASE

1. Operate temperature control dial and raise the set temperature to 32

°C (90°F).

2. Check that warm air blows from the air outlets.
Is the inspection result normal?

YES

>> GO TO 9.

NO

>> GO TO 10.

9.

CHECK AUTO MODE

1. Press AUTO switch to confirm that “AUTO” is indicated on the display.

2. Operate temperature control dial to check that air outlet or air flow changes (the air outlet or air flow varies

depending on the ambient temperature, in-vehicle temperature, set temperature, and etc.).

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> GO TO 10.

10.

CHECK SELF-DIAGNOSIS WITH CONSULT

1. Perform self-diagnosis with CONSULT.

2. Check that any DTC is detected.
Is any DTC detected?

YES

>> Refer to

HAC-33, "DTC Index"

and perform the appropriate diagnosis.

NO

>> GO TO 11.

11.

CHECK FAIL-SAFE ACTIVATION

Check that symptom is applied to the fail-safe activation. Refer to

HAC-33, "Fail-safe"

.

>> Refer to

Temperature Setting Trimmer

INFOID:0000000012200030

DESCRIPTION

If the temperature felt by the customer is different from the air flow temperature controlled by the temperature

setting, the A/C auto amp. control temperature can be adjusted to compensate for the temperature setting.

HOW TO SET

With CONSULT

Perform “TEMP SET CORRECT” of HVAC work support item.

NOTE:

• When

−3.0°C (−6°F) is corrected on the temperature setting set as 25.0°C (77°F) the temperature controlled

by A/C auto amp. is 25.0

°C (77°F) −3.0°C (−6°F) = 22.0°C (72°F) and the temperature becomes lower than

the temperature setting.

• When the battery cable is disconnected from the negative terminal or when the battery voltage becomes 10

V or less, the setting of the difference between the set temperature and control temperature may be can-

celled.

Inlet Port Memory Function (REC)

INFOID:0000000012200031

DESCRIPTION

• If the ignition switch is turned to the OFF position while the intake switch is set to ON (recirculation), “Per-

form the memory” or “Do not perform the memory” of intake switch ON (recirculation) condition can be

selected.

• If “Perform the memory” was set, the intake switch will be ON (recirculation) when turning the ignition switch

to the ON position again.

• If “Do not perform the memory” was set, the air inlets will be controlled automatically when turning the igni-

tion switch to the ON position again.

HOW TO SET

With CONSULT

Perform the “REC MEMORY SET” of HVAC work support item.
