System is equipped with self diagnostics. Perfrom the self doiagnostic to check if there are any trouble codes.
1. Self-diagnosis process
Fig. 111: Self-Diagnosis Process Flow Chart
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
a) Continuance Operation : DTC Code is One.
Fig. 112: Continuance Operation - DTC Code Is One
b) Continuance Operation : DTC Code is two.
Fig. 113: Continuance Operation - DTC Code Is Two step operation
3. Normal or one fault code is same as a continuance operation.
A. DTC Code is more two.
Fig. 114: Continuance Operation - DTC Code As More Two
B. Diagnostic procedure refer to DTC code.
a) In-car temperature sensor: Control with the value of 25 C (771 F)
b) Ambient temperature sensor: Control with the value of 20 C (67 F)
c) Evaporator temperature sensor: Control with the value of -2 C (28.4 F)
d) Humidity sensor: Control with the value of 10%
e) Water temperature sensor : Control with the value of -2 C (28.4 F)
e)Temperature control actuator (Air mix potentiometer):
f)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.
8. Intake control actuator:
Fix fresh position, while selecting fresh mode. Fix recirculation position, while selecting recirculation mode.
