Diagnostic mode table
Switch the meter display from the regular mode to the diagnostic mode. To switch the display, refer
to “DIAGNOSTIC 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.
Diagnostic
code No.
Item Description of action
Data displayed on meter
(reference value)
01
Throttle angle Displays the throttle angle.
• Check with throttle fully closed.
• Check with throttle fully open. 0 ~ 125 degrees
• Fully closed position (12 ~
22)
• Fully open position (95 ~
100)
03
Pressure difference
(atmospheric pressure
and cylinder-#1 intake
air pressure) Displays the pressure difference (atmospheric
pressure and cylinder-#1 intake air pressure).
• Generate the pressure difference by cranking
the engine with the starter, without actually
starting the engine.
• Not cranking: atmospheric
pressure
• Cranking: intake air pres-
sure decreases to less than
the atmospheric pressure.
04
Pressure difference
(atmospheric pressure
and cylinder-#2 intake
air pressure) Displays the pressure difference (atmospheric
pressure and cylinder-#2 intake air pressure).
• Generate the pressure difference by cranking
the engine with the starter, without actually
starting the engine.
• Not cranking: atmospheric
pressure
• Cranking: intake air pres-
sure decreases to less than
the atmospheric pressure.
05
Intake air temperature Displays the intake air temperature.
• Check the temperature in the air filter case. Compare it to the value dis-
played on the meter. (Mini-
mum displayed value: –30 °C
[-22.0 °F])
06
Coolant temperature Displays the coolant temperature.
• Check the temperature of the coolant. Compare it to the value dis-
played on the meter. (Mini-
mum displayed value: –30 °C
[-22.0 °F])
07
Vehicle speed pulse Displays the cumulative number of vehicle
pulses that are generated when the tire is spun. (0 ~ 999; resets to 0 after 999)
OK if the numbers appear on
the meter.
09
Fuel system voltage
(battery voltage) Displays the fuel system voltage (battery volt-
age). 0 ~ 18.7 V
Normally, approximately 12.0
V
24
Throttle switch Displays that the switch is on or off. Throttle open: on
Throttle closed: off
