SYSTEM CIRCUITS
Electrical circuits of each system are shown from the power supply through
ground points. Wiring connections and their positions are shown and
classified by code according to the connection method. (Refer to the
section, “How to use this manual”).
The “System Outline” and “Service Hints” useful for troubleshooting are also
contained in this section.
JGROUND POINTSShows ground positions of all the parts described in this manual.
KOVERALLWIRING DIAGRAMProvides circuit diagrams showing the circuit connections.HOW TO USE THIS MANUAL
This manual provides information on the electrical circuits installed on vehicles by
dividing them into a circuit for each system.
The actual wiring of each system circuit is shown from the point where the power source
is received from the battery as far as each ground point. (All circuit diagrams are shown
with the switches in the OFF position.)
When troubleshooting any problem, first understand the operation of the circuit where
the problem was detected (see System Circuit section), the power source supplying
power to that circuit (see Power Source section), and the ground points (see Ground
Points section). See the System Outline to understand the circuit operation.
When the circuit operation is understood, begin troubleshooting of the problem circuit
to isolate the cause. Use Relay Location and Electrical Wire Routing sections to find
each part, junction block and wiring harness connectors, wiring harness and wiring
harness connectors, splice points, and ground points of each system circuit. Internal
wiring for each junction block is also provided for better understanding of connection
within a junction block.
Wiring related to each system is indicated in each system circuit by arrows (from
, to ). When overall connections are required, see the Overall Wiring Diagram
at the end of this manual.
*The system shown here is an EXAMPLE ONLY. It is different
to the actual circuit shown in the SYSTEM CIRCUITS SECTION.HOW TO USE THIS MANUAL
