[AUTOMATIC AIR CONDITIONER]

AUTOMATIC AIR CONDITIONER SYSTEM

ECM judges whether compressor can be turned ON, based on each sensor status (refrigerant pressure sen-

sor signal, throttle angle sensor, etc.). If it judges compressor can be turned ON, it sends compressor ON sig-

nal to IPDM E/R, via CAN communication line.

Upon receipt of compressor ON signal from ECM, IPDM E/R turns air conditioner relay ON to operate com-

pressor.

SELF-DIAGNOSIS FUNCTION

A/C Auto Amp. Self-Diagnosis

INFOID:0000000007356348

A/C SYSTEM SELF-DIAGNOSIS FUNCTION

The self-diagnosis function is built into the A/C auto amp. to quickly locate the cause of malfunctions.

DESCRIPTION

The self-diagnostic system diagnoses sensors, CAN system, and battery voltage on A/C auto amp. Refer to

applicable sections (items) for details. Fault codes (if any are present) will be displayed in the ambient temper-

ature display area. Refer to 

HAC-25, "A/C System Self-Diagnosis Code Chart"

.

SELF-DIAGNOSTIC MODE

NOTE:

Radio must be OFF.

1. Turn the ignition switch ON.

2. On the A/C and AV switch assembly, press the "SETTING" but-

ton and twist the volume knob clockwise and counterclockwise

until the Self-Diagnosis screen shows on the display. 

3. Scroll down to "Confirmation/Adjustment" and press the

"ENTER" button.

4. Scroll down to "Climate Control" and press the "ENTER" button.

5. The fan bars will flash on the display during the self-test, and

then the fault codes will display in the ambient temperature area.

They will continue scrolling until diagnostic mode is exited.

6. Exit by pressing the "BACK" button on A/C and AV switch

assembly until display returns to its normal operation screen.

HVAC system will be OFF or by turning the ignition switch OFF.

The self-diagnostic system diagnoses sensors, CAN system, and battery voltage on A/C auto amp. Refer to

applicable sections (items) for details. Fault codes (if any are present) will be displayed in the ambient temper-

ature display area. Refer to 

HAC-25, "A/C System Self-Diagnosis Code Chart"

.

• Press the “BACK” switch and the “UP” switch within 10 seconds

after turning the ignition switch from OFF to ACC and hold them for

3 seconds or more. Then the buzzer sounds, all indicators of the

preset switch illuminate, and the self-diagnosis mode starts.

• The continuity of each switch and control dials (A/C and AV switch

assembly only) at the ON position can be checked by pressing

each switch and turning each control dial. The buzzer sounds and

LED's will illuminate if the switch is normal.

Finishing self-diagnosis mode

Self-diagnosis mode is canceled when turning the ignition switch OFF.
