INTRODUCTION

CIRCUIT CONNECTION A circuit connection is indicated by lines showing the electric wires connecting the electrical devices.

Wire size and color code As shown below, the number indicates the size of the wire (nominal sectional area of the conductor, mm2), and the letter at the end of each number indicates the color of the covering.

CEL7058A

Wire color code and symbol The color of a wire covering is indicated by an alphabetical symbol. There are two types of wire colors; one is of a unicolor, the other of a ground unicolor with an identifying stripe color.

Indication of wire joint When another wire is connected to a wire on the route, the joint position is indicated in the wiring circuit by a black dot and the wire joined thereto by an arrow, as shown in the figure.

CEL6004A

Indication of joint to same terminal The figure below indicates that a terminal connecting to a unit is also used to connect the wire leading to another unit.

CEL6005A

EL-1-3

INTRODUCTION

Indication of joint between connectors A single lead or wire is indicated by a connector at the joint in wiring diagrams. Multiple leads or wires are indicated by terminals of a connector at the joints. The connector style is separately indicated near the joints to identify the terminals.

CEL6006A

Indication of joint between unit and connector (When unit is provided with terminals) When leads emerge directly from a unit or when a unit is provided with a terminal connector, the terminal numbers corresponding to the leads are indicated by the 1st connector counting from the unit as shown in the figure.

CEL7061A

Indication of ground and battery The ground (GND) symbol is indicated only when a unit or component is directly grounded to body metal (GND) without using a lead. A combination of the ground and connector symbols are indicated for a unit or component which is grounded using a lead.

CEL7062A

Two types of batteries that are used are as shown in the figure.

CEL6008B

Diode check Check continuity using an ohmmeter. Diode is functioning properly if test results are as shown in the figure at left. Specifications may vary depending on the type of tester. Before performing this inspection, be sure to refer to the instruction manual of the tester to be used.

CEL6122K

EL-1-4

INTRODUCTION

Indication of switch The switches are illustrated as in the normal state. The switch which is off in the normal state is called a ‘‘normal open switch’’, and that which is on in the normal state is called a ‘‘normal close switch’’.

CEL6-009

NOTE + The circuit makes when the normal open switch is operated and it breaks when the normal close switch is operated.

EL-1-5

INTRODUCTION

Indication of relay The relays use normal open relays. As shown in the figure, the normal open relay makes when it is operated. The relay that breaks when it is operated is called a normal closed relay. Similar to conventional switches, relays are shown in the ‘‘OFF’’ state in wiring diagrams.

CEL6010A

Circuit operation chart All wiring diagrams show the relays in a ‘‘break’’ state in which current does not flow through the electrical components. With the exception of the above, relays which switch from one position to another, such as multi-position switches, are shown in the circuit operation chart to clearly indicate the relationship of the connections.

CEL6011D

CEL6011E

ILLUSTRATION OF CONNECTORS Connectors shown in wiring diagrams are represented in accordance with a specified standard. From the connector symbol, the number, style, type (female or male), etc. of connectors can be clearly identified to facilitate identification with those in actual vehicles.

Example 1 a. The connector symbol is divided into six sections which indicates a 6-pole connector. b. The black rectangular section (Shown at the top of the connector symbol) indicates a ‘‘male’’ connector. c. Both sides of the connector symbol are rounded to indicate a ‘‘W’’ type connector.

CEL6012B

EL-1-6

INTRODUCTION

Example 2 a. The connector symbol is divided into 8 square sections which indicates an 8-pole connector. b. The white rectangular section at the top of the connector symbol indicates a ‘‘female’’ connector. c. The four corners of the connector symbol are 90° so the symbol indicates an ‘‘M’’ type connector.

CEL6012C

HOW TO TRACE CONNECTIONS When tracing a connection between two connections, match them with connector guide placed on the other guide (as if you were closing a book). The squares facing each other in this condition are the corresponding terminals. It is wrong to trace in parallel. NOTE + The connector guide is the positioning convex part of the connector.

How to trace SMJ connections The SMJ connector is designed so that each terminal position is indicated by an alphanumerical ‘‘address’’. Since only the ‘‘address’’ is indicated in wiring diagrams, the SMJ connector chart should also be used as a guide in determining a terminal position on the SMJ connector side. The terminals of the SMJ connector can be traced in a manner similar to a conventional connector. CEL7063A

EL-1-7

INTRODUCTION

How to trace respective system power supply In each wiring diagram, power supplies located upstream of the applicable fuses are abbreviated as shown in Figures EL-13-2 & EL-13-4. To trace a power supply, the leading wiring diagrams (pages EL-13-1 to EL-13-4) should be referred to first and the required power supply can be traced back from the applicable fuse.

NOTE + The type is the nominal designation in accordance with JASO standards. + The above battery performance is based on an electrolyte specific gravity of 1.280 [20°C (68°F)]. CAUTION PRECAUTIONS FOR HANDLING ELECTRICAL UNITS + Before servicing the electrical units, be sure to disconnect the negative (−) cable from the battery to ensure safety. + Be sure to turn the key switch to ‘‘OFF’’ before disconnecting the negative (−) cable from the battery. + If any of the electrical systems and wiring are changed or modified arbitrarily, there is the possibility of vehicle trouble as well as fire due to an overloaded circuit or short circuit.

EL-3-1

BATTERY AND CIRCUIT PROTECTOR

Inspection 1. Check the electrolyte level. The battery electrolyte should be maintained between the upper and lower levels on the case. If low, add distilled water to the specified level and charge the battery for at least 30 minutes.

CT-019E

2. Using a gravimeter, measure the specific gravity of the electrolyte in each cell. Maintenance standard [Electrolyte temperature at 20°C (68°F)] 1.200 - 1.290 NOTE + Read the indication at the upper end of the electrolyte surface. + The measured specific gravity of the electrolyte must be corrected to the 20°C (68°F) standard. S20 = St + 0.0007 (t − 20) Where, S20: Specific gravity of electrolyte at standard temperature 20°C (68°F) St: Specific gravity measured at t°C t: Temperature of measured electrolyte (°C)

BATTERY AND CIRCUIT PROTECTOR

WARNING + Be careful not to spill battery electrolyte on any part of your body, clothes or finished surfaces of parts. + Do not touch your eyes with dirty hands. After handling battery electrolyte, wash your hands thoroughly under running water. + If electrolyte should come into contact with your eyes, rinse the eyes for at least fifteen minutes and immediately see a doctor. 3. Check that the battery and battery terminals are free from corrosion and dirt.

Charging the battery 1. Charge the battery with a charger while measuring the specific gravity of the electrolyte every 30 minutes. Charge until the specific gravity reads between 1.25 and 1.29 for 3 consecutive readings and all cells reach a voltage of 2.5 to 2.7 volts. NOTE + Charging should be done in a well ventilated area free from fire. + Be careful not to allow the temperature of the electrolyte to go over 45°C (113°F). + If the electrolyte level lowers during charging, add distilled water.

CEL1045A

2. When distilled water is added to the battery due to low electrolyte, always charge the battery according to step 1 above.

FUSE Inspection 1. Visually inspect each fuse. 2. If any fuse is cracked or blown, trace the cause, repair the trouble, and then replace the fuse. NOTE + Always use a fuse of the specified capacity. CEL5003A

HARNESS LAYOUT

HARNESS LAYOUT SCHEMATIC DIAGRAM The schematic diagram illustrates how each harness (main harness, chassis harness, floor harness, floor upper harness, body side harness, etc.) is wired on the actual vehicle. Depending on the vehicle model, however, the arrangements of the wires and units may sometimes be different, so the respective schematic diagrams must be carefully checked to see if they coincide with the arrangements in the actual vehicle.
