Self-diagnosis
INTRODUCTION AND GENERAL DESCRIPTION
The self-diagnostic system diagnoses sensors, door motors,
blower motor, etc. by system line. Refer to applicable sections
(items) for details. Shifting from normal control to the self-diag-
nostic system is accomplished by starting the engine (turning the
ignition switch from ªOFFº to ªONº) and pressing ª
º switch for
at least 5 seconds. The ª
º switch must be pressed within 5
seconds after starting the engine (ignition switch is turned ªONº).
This system will be canceled by either pressing
(AUTO)
switch or turning the ignition switch ªOFFº. Shifting from one step
to another is accomplished by means of turning temperature dial
clockwise or counterclockwise, as required.
Additionally shifting from STEP 4 to AUXILIARY MECHANISM is
accomplished by means of pushing
(fan) switch.
(Ignition switch OFF®ON)
Within 5 seconds after starting engine (ignition
switch is turned ªONº), press
switch for
at least 5 seconds.

ture felt by driver.
Operating procedures for this trimmer are as follows:
lBegin Self-diagnosis STEP 4 mode.
lPress(fan) switch to set system in auxiliary mode.
lTurn temperature dial clockwise or counterclockwise as
desired. Temperature will change at a rate of 1ÉC each time
