If a continuity test on an affected
harness does not slove the problem,
proceed to check by following the
inspection items listed in the chart
from left to right.
If any abnormality is found in any
inspection item, refer to the "INSPEC­
TION" section and carry out further
inspection following the procedures
described therein. In some cases, the
description of an inspection item overlaps
that of the preceding item. In
such case, the overlapping description
of the present inspection item may be
omitted.
Note that any component part of
the electronic fuel injection system
must be replaced as an assembly if it is
found to be faulty, since no repairing
is allowed.
