LIST OF OPERATION METHODS
By operating each of the A/C control switches as shown in the diagram, it is possible to enter the diagnosis check mode.


ACTUATOR CHECK




a. After entering the DTC check mode (Sensor Check Mode) press the R/F switch.
b. Since each damper, motor and relay automatically operates at 1 second intervals beginning in order from 10 in the temperature display, check the temperature and air flow visually and by hand.
If the slower display is desired, press the UPDr switch and change it to step operation. Each time the UPDr switch is pressed, the display changes by 1 step.
