Repair Procedures
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.
Fault code
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 a continuance
B. DTC code is more two
4. If fault codes are displayed during the check, Inspect malfunction causes by referring to fault codes.
5. Fail safe
(1) In-car temperature sensor: Control with the value of 23°C (73.4°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 10 W/m
(5) Temperature control actuator (Air mix potentiometer):
A. If temperature set 15°C-22.5°C, fix at maximum cooling position.
B. If temperature set 23°C-30°C, fix at maximum heating position.
(6) Mode control actuator (Direction potentiometer):
A. INDICATOR OFF : Door close position
B. INDICATOR ON : Door open position
(7) Intake control actuator
A. Fix fresh position, while selecting fresh mode.
B. Fix recirculation position, while selecting recirculation mode.
Replacement
1. Disconnect the negative (-) battery terminal.
2. Remove the mat (A).
3. Remove the upper tray (A).
4. Remove the center facia lower panel (B) by pulling it using a screw driver (-) after loosening a screw. Take care of fixing clips.
5. Disconnect the connectors (A) from the center facia.
6. Remove the heater & A/C controller (A) after loosening the screw.
7. Installation is the reverse order of removal.
