Diagnostic mode table
Set the meter display from the regular mode to the diagnosis mode. For the setting method, refer to
"DIAGNOSTIC MODE".
NOTE:
• Check the intake temperature and coolant temperature as close as possible to the area in which
the respective sensor is mounted.
• If it is not possible to check it with an atmospheric pressure gauge, judge it by using 760 mmHg
(29.9 inHg) as the standard.
• If it is not possible to check the intake temperature, use the ambient temperature as reference
(use the compared values for reference).

Description of action
Displays the throttle angle.
• Check with throttle fully closed.
• Check with throttle fully open.
Displays the atmospheric pressure.
* Use an atmospheric pressure gauge to check the atmo-
spheric pressure.
Displays the pressure difference (atmospheric pressure -
intake air pressure).
Engine stop switch is on.
* 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 cleaner case.
Displays the coolant temperature.
* Check the temperature of the coolant.
Displays the accumulation of the vehicle pulses that are gen-
erated when the tire is spun.
Displays the lean angle cut-off switch values.
Displays the fuel system voltage (battery voltage).
Engine stop switch is on.
Displays that the switch is ON or OFF. (When the gear is in a
position other than neutral.)
Displays that the switch is ON or OFF.
After 1 second has elapsed from the time the engine stop
switch has been turned from OFF to ON, it actuates ignition
coil #1 for five times every second and illuminates the engine
trouble warning light.
* Connect an ignition checker.
* If the engine stop switch is ON, turn it OFF once, and then
turn it back ON.
After 1 second has elapsed from the time the engine stop
switch has been turned from OFF to ON, it actuates ignition
coil #2 for five times every second and illuminates the engine
trouble warning light.
* Connect an ignition checker.
* If the engine stop switch is ON, turn it OFF once, and then
turn it back ON.
