Indicator
The MIL on your CRF keeps you informed, alerts
you to possible problems, and makes your riding
safer and more enjoyable. Refer to the MIL
frequently.
The MIL flashes when there is any abnormality in
the PGM-FI system. It should also light for a few
seconds and then go off when the engine is started.
If the MIL comes on at any other time, reduce
speed and refer to an official Honda Shop Manual
available for purchase from your Honda dealer.
If the MIL does not come on when it should, have
your Honda dealer check it for problems.
The MIL will blink the appropriate DTC number if
the ECM detects an active problem while the
engine is running at less than 4,000 min
–1
(rpm).
The MIL will stay on when engine speed is over
4,000 min
–1
(rpm).
The MIL has two types of blinks: a long blink and
short blink. The long blinking lasts for 1.2 seconds,
the short blinking lasts for 0.4 seconds.
One long blink is the equivalent of ten short blinks.
For example, when one long blink is followed by
two short blinks, the MIL is 12 (one long blink =
10 blinks, plus two short blinks).
When the ECM stores more than one DTC, the
MIL will indicate them by blinking in the order
from the lowest number to highest number.
The DTC is indicated in two ways according to the
failure status.
– In the case that the ECM detects an active
problem, the MIL will come on and will start to
blink the DTC when the engine is started.
– In the case that the ECM does not detect an
active problem but has recorded a previous
problem in its memory, the MIL will not come
on. If it is necessary to retrieve any past
problems stored in the memory, refer to an
official Honda Shop Manual.
