Self-diagnosis FunctionEJS004GT
DESCRIPTION
The self-diagnostic system diagnoses sensors, door motors, blower motor, etc. by system line.
Self-diagnosis is step-1 to 7. There are two ways of changing method during self-diagnosis.

Switching to self-diagnosis step-1 to 4.
Shifting from usual control to the self-diagnostic system is accomplished by starting the engine (turning
the ignition switch from OFF to ON) and pressing A/C switch for at least 5 seconds. The A/C switch must
be pressed within 10 seconds after starting the engine (ignition switch is turned ON). This system will be
canceled by either pressing intake switch or turning the ignition switch OFF. Shifting from one step to
another is accomplished be means of turning fan control dial, as required.

Switching to self-diagnosis step-5 to 7 (Auxiliary mechanism).
Shifting from usual control to the self-diagnostic system is accomplished by starting the engine (turning
the ignition switch from OFF to ON) and pressing intake switch for at least 5 seconds. The intake switch
must be pressed within 10 seconds after starting the engine (ignition switch is turned ON). This system
will be canceled by either pressing A/C switch or turning the ignition switch OFF. Shifting from one step to
another is accomplished by means of turning fan control dial, as required.

FUNCTION CONFIRMATION PROCEDURE
1. SET IN SELF-DIAGNOSTIC MODE (STEP-1 TO 4)
1. Set the fan control dial to OFF position.
2. Turn ignition switch ON.
3. Set in self-diagnostic mode as follows. Within 10 seconds after starting engine (ignition switch is turned
ON.), press A/C switch for at least 5 seconds.
CAUTION:
If battery voltage drops below 12V during diagnosis step-3, actuator speed becomes slower and as a
result, the system may generate an error even when operation is usual. To avoid this, start engine
before performing this diagnosis.
>> GO TO 2.
2. STEP-1: LEDS ARE CHECKED
Check intake and A/C switch LEDs illumination.
OK >> GO TO 3.
NG >> Refer to ATC-108, "
Self-Diagnosis" .
3. CHECK TO ADVANCE SELF-DIAGNOSIS STEP-2
1. Turn fan control dial to AUTO position.
CAUTION:
When switched to STEP-2, LED of REC position blinks for
approximately 25 seconds.
2. Advance to self-diagnosis STEP-2?
Check A/C switch LED illumination.
YES >> GO TO 4.
NO >> Replace controller.
4. CHECK TO RETURN SELF-DIAGNOSIS STEP-1
Turn fan control dial to OFF position.
Return to self
-diagnosis STEP-1?
YES >> GO TO 5.
NO >> Replace controller.

AUXILIARY MECHANISM: TEMPERATURE SETTING TRIMMER
The trimmer compensates for differences in range of ±3°C between temperature setting (Temperature control
dial position) and temperature felt by driver.
Operating procedures for this trimmer are as follows:
1. Set temperature at 25°C.
2. Set fan control dial to OFF.
3. Turn ignition switch ON.
4. Set in self-diagnostic mode as follows. Within 10 seconds after starting engine (ignition switch is turned
ON.), press intake switch for at least 5 seconds.
5. Turn temperature control dial as desired. Temperature will change at a rate of 1°C each time a dial is
turned.
When battery cable is disconnected, trimmer operation is canceled. Temperature set becomes that of initial
condition, i.e. 0°C.
AUXILIARY MECHANISM: FOOT POSITION SETTING TRIMMER
Wind distribution ratio in FOOT mode can be set.
Operating procedures for this trimmer are as follows:
1. Set temperature at 25°C.
2. Set fan control dial to AUTO.
3. Turn ignition switch ON.
4. Set in self-diagnostic mode as follows. Within 10 seconds after starting engine (ignition switch is turned
ON.), press intake switch for at least 5 seconds.
5. Turn temperature control dial as desired.

TROUBLE DIAGNOSIS

Starting Fan Speed Control
Start Up from COLD SOAK Condition (Automatic mode)
In a cold start up condition where the engine coolant temperature is below 56°C (133°F), the blower will not
operate for a short period of time (up to 150 seconds). The exact start delay time varies depending on the
ambient and engine coolant temperature.
In the most extreme case (very low ambient) the blower starting delay will be 150 seconds as described
above. After this delay, the blower will operate at low speed until the engine coolant temperature rises above
56°C (133°F), and then the blower speed will increase to the objective speed.
Start Up from Usual or HOT SOAK Condition (Automatic mode)
The blower will begin operation momentarily after the A/C switch is pushed. The blower speed will gradually
rise to the objective speed over a time period of 3 seconds or less (actual time depends on the objective
blower speed).
Blower Speed Compensation
Sunload
When the in-vehicle temperature and the set temperature are very close, the blower will be operating at low
speed. The low speed will vary depending on the sunload. During conditions of low or no sunload, the blower
low speed is usual low speed (approx. 4V). During high sunload conditions, the auto amp. causes the blower
fan speed to increase.(Approx. 7V)
Fan Speed Control Specification
COMPONENT DESCRIPTION
Fan Control Amp.
The fan control amp. is located on the intake unit. The fan control
amp. receives a gate voltage from the auto amp. to steplessly main-
tain the blower fan motor voltage in the 4 to 12 volt range.
DIAGNOSTIC PROCEDURE FOR BLOWER MOTOR
SYMPTOM: Blower motor operation is malfunctioning.
