Connector Symbols

Most of connector symbols in wiring diagrams are shown from the terminal side.

• Connector symbols shown from the terminal side are enclosed by a single line and followed by the direction mark.

  

• Connector symbols shown from the harness side are enclosed by a double line and followed by the direction mark.

• Certain systems and components, especially those related to OBD, may use a new style slide-locking type harness connector. For description and how to disconnect, refer to PG section, “Description”, “HARNESS CONNECTOR”.

• Male and female terminals

  

  Connector guides for male terminals are shown in black and female terminals in white in wiring diagrams.

HOW TO REPAIR ALUMINUM WIRES : How to Repair Aluminum Wires

PRECAUTIONS FOR THE HANDLING OF ALUMINUM WIRES

• If an aluminum wire is damaged (e.g. broken), never perform the repair method for copper wires (soldering).

• Never perform electrotap for connecting broken aluminum wires.

• To secure the wire fixing strength (a force to protect aluminum wire from being disconnected from crimp terminal) and electrical conductivity, always use the dedicated harness repair kit and caulking tool [SST: KV99112600] when repairing broken wires.

HOW TO DISTINGUISH ALUMINUM WIRES

Wiring color: Lavender (Color code: LA)

HOW TO REPAIR BROKEN WIRES

1. Insert heat shrinkable tube into the target aluminum wire beforehand.

   

2. Strip wire terminal approximately 10 mm and insert it into crimp terminal .

   CAUTION:

   Check wire size and use appropriate crimp terminal.

3. Set crimp terminal to the die (tooth) of caulking tool [SST: KV99112600].

   

   CAUTION:

   Use appropriate die (tooth) of caulking tool [SST: KV99112600] according to the crimp terminal size.

4. Apply load until the handle of caulking tool [SST: KV99112600] is released.

   

   NOTE:

   The handle of the specified caulking tool [SST: KV99112600] is not opened until crimping is completed.

5. After crimping both sides, pull wire at both ends to check that they are not disconnected from crimp terminals.

   

6. Cover the crimp terminal with heat shrinkable tube and heat the tube with industrial dryer .

   

7. After heating heat shrinkable tube , check that adhesive is squeezed out from both ends of tube to the entire perimeter.

   

8. Wind insulating tape around heat shrinkable tube for the purpose of waterproof and anticorrosion.

   

HOW TO EXTEND WIRES

When repairing a broken aluminum wire, it can be extended by connecting aluminum wire with copper wire by using crimp terminal .

HOW TO USE THIS MANUAL : Tightening Torque of Standard Bolts

Discription

This vehicle has both new standard based on ISO* and previous standard bolts/nuts. There are some differences between these two types of bolts/ nuts; shape of the head, grade of strength, hexagonal width across flats and the standard tightening torque.

• For guidance in discriminating.

• The new standard machine screws and tapping screws have a head of ISO standard torx recess.

• If the tightening torque is not described in the description or figure.

*ISO: International Organization for Standardization

Tightening Torque Table (New Standard Included)

CAUTION:

• The special parts are excluded.

• The bolts/nuts in these tables have a strength (discrimination) number/symbol assigned to the head or the like. As to the relation between the strength grade in these tables and the strength (discrimination) number/symbol, refer to “DISCRIMINATION OF BOLTS AND NUTS”.

PREVIOUS STANDARD

CAUTION:

The parts with aluminum or the cast iron washer surface/thread surface are excluded.

NEW STANDARD BASED ON ISO

CAUTION:

1. Use tightening torque with lubricant for the new standard bolts/nuts in principle. Friction coefficient stabilizer is applied to the new standard bolts/nuts.

2. However, use tightening torque without lubricant for the following cases. Friction coefficient stabilizer is not applied to the following bolts/nuts.

   • Grade 4.8, M6 size bolt, Conical spring washer installed

   • Paint removing nut (Size M6 and M8) for fixing with weld bolt
