Self-diagnosis devices
1. Engine trouble warning light “U”
2. Immobilizer system indicator light “ ”
This model is equipped with a self-diag-
nosis device for various electrical cir-
cuits. If any of those circuits are defec-
tive, the engine trouble warning light
will start flashing. If this occurs, have a
Yamaha dealer check the vehicle.
This model is also equipped with a
self-diagnosis device for the immobi-
lizer system.
Turn the key to "ON". If any of the im-
mobilizer system circuits are defec-
tive, the immobilizer system indicator
light will flash, and it will indicate an er-
ror code.
If this occurs, have a Yamaha dealer
check the vehicle. However, if the indi-
cator light slowly flashes five times,
and then quickly flashes two times re-
peatedly, this error could be caused by
signal interference. If this occurs, try
the following.
1. Use the code re-registering key to
start the engine.
NOTE:
Make sure there are no other immobi-
lizer keys close to the main switch,
and do not keep more than one immo-
bilizer key on the same key ring! Im-
mobilizer system keys may cause sig-
nal interference, which may prevent
the engine from starting.
2. If the engine starts, turn it off and
try starting the engine with the
standard keys.
3. If one or both of the standard keys
do not start the engine, take the
vehicle, the code re-registering
key and both standard keys to a
Yamaha dealer and have the
standard keys re-registered.
