Self-diagnosis Function
EJS000JK
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 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 AUTO switch or turning the ignition switch OFF. Shifting from one
step to another is accomplished by means of turning temperature dial, as required.
Additionally shifting from STEP-5 to AUXILIARY MECHANISM is accomplished by means of pushing (fan)
UP switch.
