This manual provides electrical circuit information of related vehicles. The circuits can be divided into circuits
of different systems by their functions. In each system circuit, the relations between power supply, fuses,
EG
controls, power consuming devices and earthing points are described actually (in all circuit diagrams, the
ignition switch is at OFF position).
TR
In the event of any failure of the system circuit, it is necessary to understand how the circuit (refer to System
Circuit section) works first, then status of power supply (refer to Power Supply section) and finally, the
AX operation process of circuit operation (refer to System Overview). When understanding the working
conditions of the entire system circuit, analyze and solve practical problems based on the phenomenon of the
FR failure (depending on the relays, controls, electrical consuming devices, plug & socket connectors between
harnesses, sensors, actuators, switches, and earthing points of the circuits used in the system, as well as
locations of plug & socket connectors of the electrical appliances and layout of the wiring harnesses).
