Control Assembly: Testing and Inspection

SELF-DIAGNOSIS

1. Self-diagnosis process
The F.A.T.C. module self test feature will detect electrical malfunction and provide error codes for system components with suspected failures.






NOTE: DTC data can be retrieved from the control panel directly or from the DLC using the Hi-Scan Pro.

2. How to read self-diagnostic code
After the display panel flickers three times every 0.5 second, the corresponding fault code flickers on the setup temperature display panel every 0.5 second and will show two figures. Codes are displayed in numerical format






3. Fault code display
1. Continuance operation DTC code is one.






2. Continuance operation : DTC code is more two.






3. STEP operation
A. Normal or one fault code is same as a continuance operation.
B. DTC code os more two.






4. If fault codes are displayed during the check, Inspect malfunction causes by referring to fault codes.
5. Fail sate
1. In-car temperature sensor: Control with the value of 25 °C (77 °F)
2. Ambient temperature sensor: Control with the value of 20 °C (67 °F)
3. Evaporator temperature sensor: Control with the value of -2 °C (28.4 °F)
4. Photo sensor: Control with the value of 0 w/sq.m
5. Temperature control actuator (Air mix potentiometer):
- If temperature set 17 °C - 24.5 °C, fix at maximum cooling position.
- If temperature set 25 °C - 32 °C, fix at maximum heating position.


6. Mode control actuator (Direction potentiometer):
- Fix vent position, while selecting vent mode.
- Fix defrost position, while selecting all except vent mode.

7. A.Q.S sensor: AQS operation OFF.
Intake position : the position before selecting AQS switch.
8. Water temperature sensor: control with the value of -2 °C (28.4 °F)
9. Intake control actuator
- Fix FRE position, while selecting FRE mode.
- Fix REC position, while selecting REC mode.
