51
Change-over switch
connector is loose
connection
Plug change-over switch
connector (CN8) again,
and then turn on
If it works normally,
change-over switch
connector fails on contact
Plug in connector
(CN8) firmly
52
Change-over switch is
defective
Take change-over switch
connector (CN 8) out,
then check conduction
with circuit tester
If it does't conduct when
turned on switch,
change-over switch is
defective
Replace a change-
over switch
53
Fuel viscosity is
increased by low
ambient temperature
Check whether ambient
temperature is not under
minus 4 dgree Fahrenheit
(-20
℃
) and make sure
winter fuel is used
If temperature is under
minus 4 degree
Fahrenheit or summer
fuel is used, fuel is not
sprayed normally from
the nozzle because fuel
viscosity is increased by
low ambient temperature
Warming up fuel,
refueling winter fuel
or mixing kerosene
with fuel in order to
decrease fuel
viscosity
