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.

pressure and cylinder-#1 intake air pressure).
• Generate the pressure difference by cranking
the engine with the starter, without actually
starting the engine.
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.
Displays the intake air temperature.
• Check the temperature in the air filter case.
