TROUBLE DIAGNOSIS
Self-diagnosis FunctionBJS000FX
DESCRIPTION
The self-diagnosis system diagnoses sensors, door motors, blower motor, etc. by system line. Refer to appli-
cable 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 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 AUTO switch or turning the ignition switch OFF. Shifting to the next step is
accomplished by means of pressing temperature control switch (driver side), as required.
Additionally sifting from STEP-5 to AUXILIARY MECHANISM is accomplished by means of pressing (fan)
control switch (UP).
