- Self-diagnosis process
- 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 DESCRIPTIONS Display Fail description 00 Normal 11 In-car sensor open 12 In-car sensor short 13 Ambient sensor open 14 Ambient sensor short 17 Evaporator sensor open 18 Evaporator sensor short 19 Temp door potentiometer open/short- Drive 20 Temp door potentiometer fault- Drive 21 Mode door potentiometer open/short 22 Mode door potentiometer fault 25 Intake door potentiometer open 26 Intake door potentiometer short 32 Temp door potentiometer open/short - Passenger 33 Temp door potentiometer fault - Passenger 45 APT CAN signal fault 46 - 47 RPM CAN signal fault 48 Vehicle speed CAN signal fault 49 Engine coolant temp CAN signal fault 50 Cluster ion generator fault
- Fault code display Continuance operation: DTC code is one. Continuance operation: DTC code is two more. STEP operation Normal or one fault code is same as a continuance operation. DTC code is two more.
- If fault codes are displayed during the check, Inspect malfunction causes by referring to fault codes.
- Fail safe In-car temperature sensor: Control with the value of 23°C (73.4°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) Water temperature sensor: Control with the value of 85°C (185°F) Temperature control actuator (Air mix potentiometer): If temperature setting 17°C-24.5°C (63°F-76°F), fix at maximum cooling position. If temperature setting 25°C-32°C (77°F-90°F), 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.
