of failure checking, the vehicle was working or at standstill, if the engine was hot or not, if
the air/fuel ratio was lean or rich etc.
•
If the vehicle is brought to the workshop without the irregular ignition check, this can be
confirmed by reproducing the frozen image data conditions. Besides, once the repair is
finished, confirm that conditions for an irregular ignition have not been detected (see con-
firming the driving configuration).
•
When the value of SHORT FT or LONG FT in the frozen image data is approx. ±20%, it is
probable that the air-fuel ratio tends to RICH (-20% or less) or LEAN (+20% or more).
•
When the COOLANT TEMP value in the frozen image data is lower than 80°C (176°), an
irregular ignition can be detected only during the warm-up phase.
•
If the irregular ignition can not be reproduced, this can be due to riding with low fuel, to the
inadequate use of fuel, dirty spark plug, etc.
•
An interrupted wire detected at the input line of the ionic signal between the ignition spark
plug unit and the Electronic Control Unit of the Fuel Injection, can be considered an irregular
ignition.
1.
Engine compartment visual check
•
Check the cable harness and connec-
tor connections.
•
Check that suction, bleeding, fuel and
other pipes are not disconnected or
broken, repair or replace, if necessary,
then confirm there is no irregular igni-
tion.
2.
Check the spark plug and spark of the cyl-
inder with irregular ignition
•
Remove the fuel pump relay from the
relay block. Remove the ignition coils
and the spark plugs (cylinders with ir-
regular ignition).
•
Fit the spark plug on the ignition coil.
Connect the ignition coil connector to
the coil.
•
Earth the spark plug.
•
Now, start the engine and check if the
spark plug releases sparks.
•
Otherwise, check according the proce-
dure described for spark plugs.
