8. Coolant Temperature Indicator —
When the snowmobile is started, this
indicator will flash and LOW TEMP
will be displayed until the engine
reaches operating temperature.
If the coolant temperature rises
above the operating temperature, the
indicator will flash at 70° C (158°
F). Once the coolant temperature
reaches the specified temperature of
75° C (167° F), the temperature sen-
sor will signal the ECM to go into
rich mode to protect the engine
while overheating. At this time, the
indicator will cease flashing and will
remain continuously illuminated.
9. High Beam Indicator — The indica-
tor is on whenever the high beam
mode is selected by the headlight
switch.
10. Low Oil Indicator — The indicator is
designed to alert the snowmobile oper-
ator when the oil in the oil injection
tank gets below a prescribed level.
Once the indicator illuminates during
operation of the snowmobile, the oper-
ator must periodically monitor the level
of oil in the reservoir and must fill the
reservoir the next time gasoline is
added to the gas tank.
11. Fuel Level Indicator — The indica-
tor will display whenever gas is low
in the fuel tank.
Diagnostic Codes
Diagnostic codes are activated by the
ECM and may be displayed on the read-
out screen for a number of reasons.
If a code is displayed while the engine is
running, the ECM is receiving input that
is outside of its established parameters. If
a code has been activated, take the snow-
mobile to an authorized Yamaha Snow-
mobile dealer for service. If not under
warranty, this service is at the discretion
and expense of the snowmobile owner.
CAUTION
If the indicator is illuminated, stop the
engine immediately and allow it to cool
down. If unable to either determine or
remedy the problem, take the snowmo-
bile to an authorized Yamaha Snowmo-
bile dealer for service. If not under
warranty, this service is at the discretion
and expense of the snowmobile owner.
