Check that the LED lights (diff-lock, reverse, neutral and ECT/FI) immediately after turning the ignition

If the LED fails in operation, replace the combination meter unit with a new one after checking its wire har-
ness/coupler.

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 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 " A " (RUN) position.
