- 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.
- 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 Fault code Fail description Control unit 00 Normal 11 In-car temperature sensor open (High) 12 In-car temperature sensor short (Low) 13 Ambient temperature sensor open (High) 14 Ambient temperature sensor short (Low) 17 Evaporator temperature sensor open (High) 18 Evaporator temperature sensor short (Low) 19 Temp door potentiometer open/short (DR) 20 Temp door motor (DR) 21 Mode door potentiometer open/short 22 Mode door control motor 23 Auto defogging sensor open (High) 24 Auto defogging sensor short (Low) 25 Intake door potentiometer open/short 26 Intake door potentiometer motor 27 AQS sensor open 28 AQS sensor short 31 AQS sensor fault 32 Temp door potentiometer open/short (PA) 33 Temp door motor (PA) 34 Console mode door potentiometer open/short 35 Console mode door potentiometer motor 36 Console temp door potentiometer open/short 37 Console temp door potentiometor motor 43 Auto defogging potentiometer open/short 44 Auto defogging potentiometer motor 45 APT can signal fault 47 RPM can signal fault 48 Vehicle speed can signal fault 49 Engine water temp can signal fault
- Fault code display Continuance operation: DTC code is one Continuance operation: DTC code is more two Step operation Normal or one fault code is same a continuance DTC code is more two
- If fault codes are displayed during the check, Inspect malfunction causes by referring to «FAULT CODES»(ref-590440-S31683731972013121700000) .
- Fail safe In-car temperature sensor: Control with the value of 25°C (77°F) Ambient temperature sensor: Control with the value of 20°C (67°F) Evaporator temperature sensor: Control with the value of -2°C (28.4°F) Temperature control actuator (Air mix potentiometer): If temperature setting 17°C-24.5°C, fix at maximum cooling position. If temperature setting 25°C-32°C, fix at maximum heating position Mode control actuator (Direction potentiometer): Fix vent position, while selecting vent mode. Fix defrost position, while selecting all except vent mode. Intake control actuator: Fix fresh position, while selecting fresh mode. Fix recirculation position, while selecting recirculation mode. AQS sensor: AQS operation OFF. Intake position: The position before selecting AQS switch. Photo sensor: Control with the value 0w/m2 Console temp switch: When the console temperature S/W voltage is less than 0.1 V; Fix cool position. When the console temperature S/W voltage is more than 4.9 V; Fix warm position. Console vent potention meter: When the console temperature S/W voltage is less than 2.5 V; Fix cool position. When the console temperature S/W voltage is more than 2.5 V; Fix warm position. Console temp potention meter: When the console temperature S/W voltage is less than 2.5 V; Fix cool position. When the console temperature S/W voltage is more than 2.5 V; Fix warm position. Console door potention meter: Fix close position, while selecting vent mode. Fix open position, while selecting all except vent mode. Auto defog sensor: Control with the value of 0%.
