ELECTRICAL SYSTEM 

 

ELECTRICAL PARTS 
Battery cable

 

·Before disconnecting connector or removing 
    electrical parts, disconnect the negative battery 
  cable. 

 

 

 

 

 

 

 

Wiring Harness 
·To remove the wiring harness from the clip in the 
    engine room, pry up the hook of the clip using a   
  flathead screwdriver. 
 

 

 

 

 

 

CONNECTORS 
Disconnecting connectors 
·When disconnecting connector, grasp the   
    connectors, not the wires.

 

 

 

 

 

 

 

 
·Connectors can be disconnected by pressing or 
    pulling the lock lever as shown. 
 

 

 

 

 

 

GI-8

Locking connector   
·when locking connectors, listen for a click   
    indicating they are securely locked.

 

 

 

 

 

 

 

 

 

Inspection 
·When a tester is used to inspect for continuity or 
    measuring voltage, insert the tester probe from 
    the wiring harness side. 
 
 
 
 
 
 
 
·Inspect the terminals of waterproof connectors 
    from the connector side since they cannot be 
    accessed from the wiring harness side. 
 
      Caution  

·To prevent damage to the terminal, wrap   

a thin wire around the tester probe before 

  inserting into terminal

 

 

 

 

Terminals 
Inspection  
·Pull lightly on individual wires to verify that they   

are secured in the terminal. 

 

 

 

 

 

 

 

GI-9

Replacement 
·Use the appropriate tools to remove a terminal as 
    shown. When installing a terminal, be sure to 
    insert it until it locks securely. 
·Insert a thin piece of metal from the terminal side 
    of the connector and with the terminal locking tab 
    pressed down, pull the terminal out from the   
  connector. 

 

 

 

Sensors, Switches, and Relays 
·Handle sensors, switches, and relays carefully. 
    Do not drop them or strike them against other 
  objects. 

 

 

 

 

 
Wiring Harness 
Wiring color codes 
·Two-color wires are indicated by a two-color code symbol. 
·The first letter indicates the base color of the wire and the second the color of the stripe.

Fuse 
Replacement 
·When replacing a fuse, be sure to replace it with 
    one of the same capacity. If a fuse fails again, the 
    circuit probably has a short and the wiring should 

be inspected. 

·Be sure the negative battery terminal is 
    disconnected before replacing a main fuse. 
·When replacing a pullout fuse, use the fuse 
  puller.

ELECTRICAL TROUBLESHOOTING TOOLS 
Jumper wire 
·A jumper wire is used to create a temporary 
    circuit. Connect the jumper wire between the 
    terminals of a circuit to bypass a switch. 
       

Caution 

      ·Do not connect a jumper wire from the 

  power source line to a body ground. This 
  wiring harnesses or electronic 
 components. 

 
Voltmeter 
·The DC voltmeter is used to measure circuit 
    voltage. A voltmeter with a range of 15V or more 
    is used by connecting the positive (+) probe (red 
    lead wire) to the point where voltage will be 
    measured and the negative (-) probe (black lead 
    wire) to a body ground. 
 
 
 
 
Ohmmeter 
·The ohmmeter is used to measure the resistance 
    between two points in a circuit and to inspect for 
    continuity and short circuits. 
      Caution 
      ·Do not connect the ohmmeter to any 

circuit where voltage is applied. This will

damage the ohmmeter.
