DETECTED FAILURE CONDITION
ITEM
EXCVA position sensor produces fol-
lowing voltage.
0.1 V sensor voltage < 4.9 V
In other than the above range, C46
(P1675) is indicated.
When no actuator control signal is
supplied from the ECM, communica-
tion signal does not reach ECM or
operation voltage does not reach
EXCVA motor, C46 (P1658) is indi-
cated. EXCVA can not operate.
EXCVA position sensor voltage is
higher than specified value.
EXCVA position sensor voltage is
lower than specified value.
When no actuator control signal is
supplied from the ECM, communica-
tion signal does not reach ECM or
operation voltage does not reach
EXCVA motor, C46 (P1658) is indi-
cated. EXCVA motor can not operate.
PAIR control solenoid valve voltage is
not input to ECM.
Cooling fan relay signal is not input to
ECM.
EVAP system purge control solenoid
valve voltage is not input to ECM.
Speedometer does not recieve signal
from the vehicle speed sensor for
more than 6 sec. when the motorcycle
is running.
ECM does not receive signal from the
vehicle speed sensor for more than 6
sec. when the motorcycle is running.
Failure in communication between
ECM and speedometer with reference
to vehicle speed.
