Self-diagnosis Function




DESCRIPTION
The self-diagnosis system diagnoses sensors, door motors, blower motor, etc. by system line. Refer to applicable sections (items) for details. Shifting from usual control to the self-diagnosis system is accomplished by starting the engine (turning the ignition switch ON) and pressing OFF switch for at least 5 seconds. The OFF switch must be pressed within 10 seconds after starting the engine (ignition switch is turned ON). This system will be canceled by either pressing AUTO.ECON switch or turning the ignition switch OFF. Shifting from one step to another is accomplished by means of turning Temperature control dial, as required.

Additionally shifting from STEP-5 to AUXILIARY MECHANISM is accomplished by means of pushing (fan) UP switch.
