Self-diagnosis FunctionEJS004GT
DESCRIPTION
The self-diagnostic system diagnoses sensors, door motors, blower motor, etc. by system line.
Self-diagnosis is step-1 to 7. There are two ways of changing method during self-diagnosis.

Switching to self-diagnosis step-1 to 4.
Shifting from usual control to the self-diagnostic system is accomplished by starting the engine (turning
the ignition switch from OFF to ON) and pressing A/C switch for at least 5 seconds. The A/C switch must
be pressed within 10 seconds after starting the engine (ignition switch is turned ON). This system will be
canceled by either pressing intake switch or turning the ignition switch OFF. Shifting from one step to
another is accomplished be means of turning fan control dial, as required.

Switching to self-diagnosis step-5 to 7 (Auxiliary mechanism).
Shifting from usual control to the self-diagnostic system is accomplished by starting the engine (turning
the ignition switch from OFF to ON) and pressing intake switch for at least 5 seconds. The intake switch
must be pressed within 10 seconds after starting the engine (ignition switch is turned ON). This system
will be canceled by either pressing A/C switch or turning the ignition switch OFF. Shifting from one step to
another is accomplished by means of turning fan control dial, as required.
