  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 DTC REFERENCE NO.

  3. 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 as a continuance operation. DTC code or more two.
  4. Diagnostic procedure. refer to AIR CONDITIONING SYSTEM DIAGNOSIS .
  5. Fail safe
  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. Humidity sensor: Control with the value of 10%
  5. Temperature sensor : Control with the value of -2°C (28.4°F)
  6. 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.
  7. 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.
