Diagnostic mode table
Switch the meter display from the regular mode to the diagnosis mode. To switch the display, refer to
"DIAGNOSTIC MODE".
NOTE:
S Check the intake air temperature and coolant temperature as close as possible to the intake air tem-
perature sensor and the coolant temperature sensor respectively.
S If it is not possible to check it with an atmospheric pressure gauge, judge it by using 101.3 kPa as the
standard.
S If it is not possible to check the intake air temperature, use the ambient temperature as reference.

Description of action
Displays the throttle angle.
S Check with throttle fully closed.
S Check with throttle fully open.
Displays the atmospheric pressure.
* Use an atmospheric pressure gauge to check the
atmospheric pressure.
Displays the 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
generated 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 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 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.
