A/C System Self-diagnosis FunctionEJS006BG
DESCRIPTION
The self-diagnostic system diagnoses sensors, door motors, blower motor, etc. Refer to applicable sections
(items) for details. Shifting from usual control to the self-diagnostic system is accomplished by turning the igni-
tion switch ON and pressing the down blower arrow switch while turning the passenger temperature dial in
either direction (hold momentarily). Within 3 seconds of doing this, press the AUTO switch. The blower bars
will flash and the ambient temperature display will indicate 0°during the self-diagnosis. Fault codes (if any are
present) will be displayed in the ambient temperature display area. Refer toAT C - 5 6 , "
