How to read electric wire code (Hybrid)
• This section describes the wire code unique to the hybrid models.
• 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.
Example) AEX0.85L: Indicates blue, heat-resistant, low-voltage wire for automobile, having nominal No. of
0.85
Indicates type of wire by symbol.
Type, symbol, and material of wire are shown in Table 1.
AEX
(Since the use of AV, AVS, AVSS, and CAVS wires depends on size (nominal No.), their
symbols are not indicated on the electrical circuit diagram.)
Indicates size of wire by nominal No.
0.85
Sizes (Nominal Nos.) are shown in Table 3.
Indicates color of wire by color code.
L
Color codes are shown in Table 7.
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 but different from AV, AVS, and AVSS in material of the cover.
CAVS has a circular compressed conductor and different appearance from AV and AVS.
