OPERATION INSPECTION

Work Procedure

INFOID:0000000006545820

The purpose of the operational check is to check that the individual system operates normally.

1.

CHECK MEMORY FUNCTION

1.

Set temperature to 30

°

C 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

1.

Press A/C switch. The A/C switch indicator is turns ON.

2.

Check visually and by sound that the compressor operates.

3.

Press A/C switch again The A/C switch indicator is turns OFF.

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.
