HOW TO READ CIRCUIT DIAGRAMS
The circuit of each system from the fuse (or fusible link) to ground is shown. The power supply is shown at the top and the ground at the bottom to facilitate understanding of how the current flows. Some variations are included in one circuit diagram. Accordingly, some diagrams may not be applicable for individual vehicles. The circuit diagrams show the state when switches are operated.

CONNECTOR/GROUNDING INDICATIONS
Scheme 555
CONNECTOR/GROUNDING MARKINGS REFERENCE CHART Item No. Connector/Grounding Symbol Contents Connector and terminal marking 1 The male and female terminals are indicated as shown. The connector with male terminal(s) is called as male connector and indicated by two connector contour lines, while the connector with female terminal(s) is called as female connector and indicated by single connector contour line. Connector symbol marking 2 The symbol indicates the connector is viewed as shown. At a device connection, the connector symbol on the device side is shown. For an intermediate connector, the male connector symbol is shown. For spare connectors and check connectors, no device is connected, and so the harness-side connector symbol is shown for these connectors. However, a data link connector is exceptional. Connector connection marking 3 Connection between a device and the harness is either by direct insertion in the device (direct connection type) or by connection with a harness connector furnished on the device side (harness connection type). The two types are indicated as illustrated. 4 5 Ground marking 6 Grounding is either by body ground, device ground or control unit interior ground. These are indicated as illustrated. 7 8

WIRE COLOR CODES REFERENCE CHART
If a cable has two colors, the first of the two color code characters indicates the basic color (color of the cable coating) and the second indicates the marking (tracer) color.
| No. | Meaning |
|---|---|
| 1 | Flexible wire |
| Twisted wire | |
| 2 | Wire size (mm 2 ) (1) |
| 3 | Basic color (color of the cable coating) |
| 4 | Marking color |
| (1) No code indicates 0.5 mm 2 (0.0008 in 2 ). Cable color code in parentheses indicates 0.3 mm 2 (0.0005 in 2 ). | |
| (1) | No code indicates 0.5 mm 2 (0.0008 in 2 ). Cable color code in parentheses indicates 0.3 mm 2 (0.0005 in 2 ). |

JOINT CONNECTOR
Note. IN THE ACTUAL VEHICLES, SOME OF THE J/C TERMINALS IN THE SAME BUS ARE USED, SO IN SOME CASES, THE TERMINAL ARRANGEMENT INDICATED ON THE CIRCUIT DIAGRAMS DOES NOT AGREE WITH THE ONES IN THE ACTUAL VEHICLES. AS FOR J/C (CAN1, 2, 3, 4), REFER TO CONTROLLER AREA NETWORK (CAN) or CONTROLLER AREA NETWORK (CAN) . IN ADDITION, ON J/C (CAN1, 2, 3, 4), THE TERMINAL NUMBERS INDICATED ON THE CIRCUIT DIAGRAMS SHOULD ALWAYS AGREE WITH THE TERMINAL ARRANGEMENT IN THE ACTUAL VEHICLES.
