• Check the LCD and LED operations when the resistance is
adjusted to the specified values.
If either one or all indications are abnormal, replace the combi-
nation meter with a new one.
NOTE:
If the engine stop switch is turned OFF or side-stand/ignition
inter-lock system is not working while the ignition switch is ON,
the LCD displays “CHEC”. But it is not a malfunction.
This condition implies that combination meter receives no signal
from the ECM.
In that case, they are restored to normal indication by turning the
engine stop switch to RUN position.
When connecting and disconnecting the engine cool-
ant temperature sensor lead wire coupler, make sure
to turn OFF the ignition switch, or electronic parts
