Diagnostic mode table
Switch the meter display from the regular mode to the diagnostic mode. To switch the display, refer to "DIAG-
NOSTIC MODE".
TIP
• Check the intake air temperature and coolant temperature as close as possible to the intake air temperature
sensor and the coolant temperature sensor respectively.
• If it is not possible to check the intake air temperature, use the ambient temperature as reference.

Description of action
Displays the throttle angle.
• Check with throttle fully closed.
• Check with throttle fully open.
Displays the intake air pressure for cylinders #1, #2, and
#3.
Displays the intake air pressure for cylinder #1.
Displays the intake air temperature.
• Check the temperature in the air filter case.
Displays the coolant temperature.
• Check the temperature of the coolant.
Displays the cumulative number of snowmobile pulses
that are generated when the track is spun.
Displays the fuel system voltage (battery voltage).
Displays that the switch is on or off.
If the grip warmer side of the grip/thumb warmer adjust-
ment switch is pushed, actuates the thumb warmer and
displays the self-diagnosis warning indicator for 120 sec-
onds.
If the grip warmer side of the grip/thumb warmer adjust-
ment switch is pushed, actuates the cylinder-#1 ignition
coil and displays the self-diagnosis warning indicator
(five times at one-second intervals).
If the grip warmer side of the grip/thumb warmer adjust-
ment switch is pushed, actuates the cylinder-#2 ignition
coil and displays the self-diagnosis warning indicator
(five times at one-second intervals).
If the grip warmer side of the grip/thumb warmer adjust-
ment switch is pushed, actuates the cylinder-#3 ignition
coil and displays the self-diagnosis warning indicator
(five times at one-second intervals).
If the grip warmer side of the grip/thumb warmer adjust-
ment switch is pushed, actuates injector #1 and displays
the self-diagnosis warning indicator (five times at one-
second intervals).
If the grip warmer side of the grip/thumb warmer adjust-
ment switch is pushed, actuates injector #2 and displays
the self-diagnosis warning indicator (five times at one-
second intervals).
