Hybrid
a The information about the wires unique to each hybrid machine model is described.
In the electric circuit diagram, the material, thickness, and color of each electric wire are indicated by symbols.
The electric wire code is helpful in understanding the electric circuit diagram.
1.
Type, symbol, and material
AV, AVS and AVSS are different in only thickness and outside diameter of the cover. AEX is similar to AV
in thickness and outside diameter of AEX and different from AV, AVS and AVSS in material of the cover.
CAVS is circular compressed conductor in conductor and different appearance from AV and AVS.
Example: AEX 0.85 L — Indicates blue, heat-resistant, low-voltage wire for automobile, having nominal No.
of 0.85
Indicates color of wire by color code.
Color codes are shown in Table 3.
Indicates size of wire by nominal No.
Size (Nominal No.) is shown in Table 2.
Indicates type of wire by symbol.
Type, symbol, and material of wire are shown in Table 1.
(Since the use of AV, AVS, AVSS, and CAVS wires depend on size (nominal No.),
their symbols are not indicated on the diagram.)
