TROUBLE DIAGNOSIS
Self-diagnosis Function
EJS001GX
DESCRIPTION
The self-diagnostic system diagnoses sensors, door motors, blower motor, etc. by system line. Refer to appli-
cable sections (items) for details. Shifting from normal control to the self-diagnostic system is accomplished
by starting the engine (turning the ignition switch from OFF to 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 A/C switch or turning the ignition switch OFF.
Shifting from one step to another is accomplished by means of turning temperature dial, as required.
