A/C AUTO AMP.

A/C AUTO AMP.

Description

INFOID:0000000003941321

COMPONENT DESCRIPTION

A/C Auto Amp. (Air Conditioner Automatic Amplifier)

The A/C auto amp. (1) has a built-in microcomputer that processes
information sent from various sensors needed for air conditioner
operation. The air mix door motors, the mode door motor, the intake
door motor, the blower motor and the compressor are then con-
trolled.
When the various switches and temperature control dial are oper-
ated, data is input to the A/C auto amp. from the A/C control.

Component Function Check

INFOID:0000000003940728

1.

CHECK OPERATION

1.

Press the AUTO switch, and then check that “AUTO” is shown on the display. 

2.

Operate the temperature control dial (driver side). Check that the fan speed or outlet changes. (The dis-
charge air temperature or fan speed varies depending on the ambient temperature, in-vehicle tempera-
ture, and temperature setting.) 

Does it operate normally?

YES

>> INSPECTION END

NO

>> Perform trouble diagnosis for the A/C system. Refer to 

HAC-192, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000003940729

1.

INSPECTION BY FAIL-SAFE FUNCTION

1.

Turn the ignition switch ON.

2.

After approximately 30 seconds, check that the air conditioner is operated by the fail-safe function (the
operation display of air conditioner is not performed). Refer to

CONDITIONER SYSTEM : Fail-Safe"

 (WITHOUT INTELLIGENT AIR CONDITIONER SYSTEM) or 

HAC-

223, "WITH INTELLIGENT AIR CONDITIONER SYSTEM : Fail-Safe"

 (WITH INTELLIGENT AIR CONDI-

TIONER SYSTEM).

Is the fail-safe function operated? 

YES

>> GO TO 3.

NO

>> GO TO 2.

2.

CHECK A/C AUTO AMP. POWER SUPPLY CIRCUIT AND GROUND

Check A/C auto amp. power supply circuit and ground circuit. Refer to 

HAC-192, "Diagnosis Procedure"

.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace parts according to the inspection results.

3.

CHECK PRESET SWITCH

Check the preset switch. Refer to 

AV-164, "Symptom Table"

 (BASE AUDIO AND DISPLAY SYSTEM), 

AV-372,

"Symptom Table"

 (BOSE AUDIO WITHOUT NAVIGATION) or 

AV-640, "Symptom Table"

 (BOSE AUDIO WITH

NAVIGATION). 
Is the inspection result normal?
