The ºCurrent Flow Chartº section, describes which parts each power source (fuses, fusible links, and circuit breakers)
transmits current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each system
are explained. Since all System Circuit diagrams start from the power source, the power source system must be fully
understood.

PROBLEM SYMPTOMS TABLE
The suspected circuits or parts for each problem symptom are shown in the table below. Use this table to
troubleshoot when, during a DTC check, a ºNormalº code is displayed but the problem is still occurring. Num-
bers in the table show the inspection order in which the circuits or parts should be checked.
HINT:
In some cases, the problem is not detected by the diagnostic system even though a problem symptom is
present. It is possible that the problem is occurring outside the detection range of the diagnostic system, or
that the problem is occurring in a completely different system.
