EAU34133
Multi-function display
WARNING

EWA12311
Be sure to stop the vehicle before
making any setting changes to the
multi-function display.
The multi-function display is equipped
with the following:

a fuel meter

a coolant temperature meter

an odometer (which shows the to-
tal distance traveled)

two tripmeters (which show the
distance traveled since they were
last set to zero)

a fuel reserve tripmeter (which
shows the distance traveled since
the bottom segment of the fuel
meter and fuel level warning sym-bol started flashing)

a self-diagnosis device

a clock

an ambient temperature display

an oil change indicator

a V-belt replacement indicator
NOTE:


Be sure to turn the key to “ON” be-
fore using the “SELECT” and “RE-
SET” buttons.

When the key is turned to “ON”, all
of the display segments of the
multi-function display will appear
one after the other and then disap-
pear, in order to test the electrical
circuit.
Odometer and tripmeter modes
Pushing the “SELECT” button switches
the display between the odometer
mode “ODO” and the tripmeter modes
“TRIP” in the following order:
ODO
→
TRIP (top)
→
TRIP (bottom)

periodic oil change to be indicated at
the correct time. (See page 6-12.)
The electrical circuit of the indicator can
be checked according to the following
procedure.
1. Set the engine stop switch to “ ”
and turn the key to “ON”.
2. Check that the indicator comes on
for a few seconds and then goes
off.
3. If the indicator does not come on,
have a Yamaha dealer check the
electrical circuit.
NOTE:

The oil change indicator may flash
when the engine is revved with the
scooter on the centerstand, but this
does not indicate a malfunction.
V-belt replacement indicator
“V-BELT”
This indicator flashes every 20000 km
(12000 mi) when the V-belt needs to be
replaced.
The electrical circuit of the indicator can
be checked according to the following
procedure.1. Turn the key to “ON” and make
sure that the engine stop switch is
set to “ ”.
2. If the indicator does not come on,
have a Yamaha dealer check the
electrical circuit.
Self-diagnosis device
This model is equipped with a self-diag-
nosis device for various electrical cir-
cuits.
If any of those circuits are defective, the
multi-function display will indicate a
two-digit error code (e.g., 12, 13, 14).
If the multi-function display indicates
such an error code, note the code num-
ber, and then have a Yamaha dealer
check the vehicle.
CAUTION:

ECA11790
If the multi-function display indi-
cates an error code, the vehicle
should be checked as soon as pos-
sible in order to avoid engine dam-
age.
This model is also equipped with a
self-diagnosis device for the immobiliz-er system.
If any of the immobilizer system circuits
are defective, the immobilizer system
indicator light will flash, and then the
multi-function display will indicate a
two-digit error code (e.g., 51, 52, 53)
when the key is turned to “ON”.
NOTE:

If the multi-function display indicates er-
ror code 52, this could be caused by
transponder interference. If this error
appears, 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 immobilizer
key on the same key ring! Immobilizer
system keys may cause signal interfer-
ence, which may prevent the engine
from starting.
2. If the engine starts, turn it off, and
try starting the engine with the
standard keys.
