FRE ( ) when the D/F ( ) or DEF ( ) is selected.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Check mode door system. Refer to HAC-80, "MODE DOOR MOTOR : Diagnosis Procedure"
.

3. Listen for the intake door position change. (Slight change of blower sound can be heard.)
NOTE:
Confirm that the A/C compressor clutch is engaged (sound or visual inspection) and the FRE ( ) switch is
pressed when the D/F ( ) or DEF ( ) is selected.
Is the inspection result normal?
YES >> GO TO 5.
NO >> Check intake door system. Refer to HAC-81, "INTAKE DOOR MOTOR : Diagnosis Procedure"
.
5.CHECK A/C SWITCH
1. Press the A/C switch.
2. The A/C switch indicator is turned ON.
Confirm that the A/C compressor clutch engages (sound or visual inspection).

6.CHECK TEMPERATURE DECREASE
1. Operate the A/C compressor.
2. Operate the temperature control switch (drive r side) and lower the temperature setting to 18°C (60 °F).
3. Check that the cool air blows from the outlets.
Is the inspection result normal?
YES >> GO TO 7.
NO >> Check for insufficient cooling. Refer to HAC-96, "Diagnosis Procedure"
.
7.CHECK TEMPERATURE INCREASE
1. Operate the temperature control switch (drive r side) and raise the temperature setting to 32°C (90 °F) after
warming up the engine.
2. Check that the warm air blows from the outlets.
Is the inspection result normal?
YES >> GO TO 8.
NO >> Check for insufficient heating. Refer to HAC-98, "Diagnosis Procedure"
.
8.CHECK DUAL MODE FUNCTION
1. Press the DUAL mode switch, and then check that “DUAL” is shown on the display.
2. Operate the temperature control switch (driver si de). Check that the discharge air temperature (driver
side) changes.
3. Operate the temperature control switch (passenger side). Check that the discharge air temperature (pas-
senger side) changes.
4. Press the DUAL mode switch, and then check that the temperature setting (driver/passenger) is unified to
the driver side temperature setting.
Is the inspection result normal?
YES >> GO TO 9.
NO >> Refer to HAC-94, "Diagnosis Chart By Symptom"
and perform the appropriate diagnosis.
9.CHECK AUTO MODE
1. Press the AUTO switch, and then check t hat “AUTO” is shown on the display.
2. Operate the temperature control switch (driver side) . Check that the fan speed, outlet air or intake air
changes. The discharge air temperature or fan speed varies depending on the ambient temperature, in-
vehicle temperature, and temperature setting.
Is the inspection result normal?
YES >> Inspection End
NO >> Refer to HAC-94, "Diagnosis Chart By Symptom"
and perform the appropriate diagnosis.

SYSTEM SETTING
Temperature Setting TrimmerINFOID:0000000009463111
Description
If the temperature felt by the customer is different
than the airflow temperature controlled by the temperature
setting, the auto amplifier control temperature can be adjusted to compensate for the temperature setting.
How to set
Using CONSULT, perform “TEMP SET CORRECT” in “WORK SUPPORT” of HVAC.
NOTE:
• When the temperature setting is set to 25.0 °C (77 °F) and −3.0 °C ( −6 °F), the temperature controlled by auto amp is 25.0 °C (77 °F) −
3.0 °C (6 °F) = 22.0 °C (71 °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 10V or less, the setting of the
difference between the temperature setting and control temperature may be cancelled.
Foot Position Setting TrimmerINFOID:0000000009463112
Description
In the FOOT mode, the air blowing to the DEF can be turned ON/OFF.
How to set
Using CONSULT, perform “BLOW SE T” in “WORK SUPPORT” of HVAC.
NOTE:
When the battery cable is disconnec ted from the negative terminal or when the battery voltage becomes 10V
or less, the setting of the discharge air mix ratio in FOOT mode may be cancelled.
