BASIC INSPECTION
In many cases, by carrying out the basic engine check shown in the following flow chart, the location causing
the problem can be found quickly and efficiently. Therefore, use of this check is essential in engine trouble-
shooting.
If there is a problem, and a normal code is displayed, proceed to the matrix chart of problem symptoms on page
EG±408. Make sure that every likely cause of the problem is checked.
EG±408.
Is battery positive voltage 11 V or more when engine is stopped?
Is engine cranked?
Does engine start?
Check air filter.
Charge or replace battery.
Proceed to matrix chart of problem symptoms
on page EG±408.
Repair or replace.
Remove air filter.
Visually check that the air filter is not excessive dirty or
oily.
If necessary, clean the air filter with compressed air. First
blow from inside thoroughly, then blow from outside of
