PROBLEM SYMPTOMS TABLE
The suspected circuits or parts for each problem symptom are shown in the t\
able below. Use this table to
troubleshoot the problem when a Normal code is displayed in the diagnostic trouble c\
ode chart but the prob-
lem is still occurring. Numbers in the table indicate the order in which\
the circuits or parts should be checked.
HINT:
When the problem is not detected by the diagnostic system even though the pr\
oblem symptom is present,
it may be that the problem is occurring outside the detection range of t\
he diagnostic system.
