the temperature of the air drawn into the air fil-
ter case. Push the “RESET” button to switch

intake temperature display.
NOTE:
• Even if the air intake temperature is set to be
displayed, the coolant temperature warning
light comes on when the engine overheats.
• When the key is turned to “ON”, the coolant
temperature is automatically displayed, even
if the air intake temperature was displayed
prior to turning the key to “OFF”.
• When the air intake temperature display is
selected, “A” is displayed before the temper-
ature.
Self-diagnosis device
This model is equipped with a self-diagnosis
device for various electrical circuits.
If any of those circuits are defective, the engine
trouble warning light will come on, and then the
display will indicate a two-digit error code.
This model is also equipped with a self-diagno-
sis device for the immobilizer system.
If any of the immobilizer system circuits are
defective, the immobilizer system indicator
light will flash, and then the display will indicate
a two-digit error code.
NOTE:
If the display indicates error code 52, this could
be caused by transponder interference. If this
error code appears, try the following.
1. Use the code re-registering key to start the
engine.
NOTE:
Make sure there are no other immobilizer 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
interference, which may prevent the engine
from starting
2. If the engine starts, turn it off and try start-
ing 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.
If the display indicates any error codes, note
the code number, and then have a Yamaha
dealer check the vehicle.
