FAIL-SAFE FUNCTION
If malfunction occurs in the ABS electric system, this sets valve relay OFF. Consequently, motor relay will be
set OFF and the indicator light ON, and no current will be applied to motor solenoid valve inactivating ABS
and turning ABS indicator light ON. In this case, it functions as the normal brake. However, if
a
malfunction
occurs while ABS is being activated, when ABS control unit diagnoses that the operation can continue, it will
effectuate ABS provisional control (turning the ABS indicator light ON). Upon the moment when ABS provi-
sional control is over, the valve relay will be set OFF.
SELF-DIAGNOSIS FUNCTION AND ABS INDICATOR LIGHT
The ABS control unit performs the self-diagnosis and can store any electronically detected malfunctions as
diagnostic trouble codes. If a malfunction has occurred, the indicator light lights up to inform the rider of the
malfunction. The special tool, when connected to the mode select coupler, enables the ABS indicator light to
display the diagnostic trouble codes.
ABS INDICATOR LIGHT
The ABS indicator light informs the rider of any ABS malfunc-
tions. If a malfunction occurred, the ABS indicator light flashes,
during the self-diagnosis, to indicate the diagnostic trouble code
so that the correct part can be repaired.
• When the ignition switch is turned to ON, the ABS indicator
light lights up even if no malfunction has occurred, to indicate
that the bulb is not burnt out. It will go off after the motorcycle
is ridden at more than 5 km/h (3.1 mile/h).
• If an ABS malfunction has occurred, the ABS indicator light
keeps lighting up.
• When a malfunction has occurred in the ABS, connect the
special tool to the mode select coupler to display the diagnos-
tic trouble code on the ABS indicator light. (
