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.
IGROUND POINTShows ground positions of all parts described in this manual.
JPOWER SOURCE(Current Flow Chart)Describes power distribution from the power supply to various electrical loads.
KCONNECTOR LISTDescribes the form of the connectors for the parts appeared in this book.This section is closely related to the system circuit.
LPART NUMBER OFCONNECTORSIndicates the part number of the connectors used in this manual.

YARIS (EM01V0U)HOW TO USE THIS MANUALB
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 Point 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 Wiring Routing
sections to find each part, junction block and wiring harness connectors, wiring
harness and wiring harness connectors 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 Electrical
Wiring Diagram at the end of this manual.
