Diagnosis

General Information Diagnosis

The troubles on TOD are classified into the group that can
be identified by the lighting status of the TOD indicator
lamps and those that can be recognized as abnormal
phenomena of the vehicle by the driver.
The troubles that can be identified by the lighting status of
the TOD indicator lamps are examined by the procedures
“Diagnosis from Trouble Codes” and “Trouble Diagnosis
Depending on The Status of TOD Indicator”. The troubles
that can be recognized as abnormal phenomena of the
vehicle by the driver are examined by the procedure
“Diagnosis from symptom”.

Self-diagnosis

The control unit has a function of self-diagnosis. If a
trouble occurs in the course of system startup, the control
unit blinks the CHECK lamp and saves the trouble code.

C07RW021

NOTE: If an intermittent fault occurs, the control unit
stops blinking upon removal of the fault. The trouble code
is saved to the control unit.
