## WIRING DIAGRAM

## INSPECTION PROCEDURE

1.INSPECT FUSE (TAIL)

1. Remove the TAIL fuse from the instrument panel junction block (driver side junction block).

1. Measure the resistance of the fuse.

   Standard resistance:
     Below 1 Ω

| NG |

REPLACE FUSE

OK |

2.CHECK COMBINATION METER BUZZER OPERATION

1. Check the key reminder warning buzzer operation.

   1. Turn the ignition switch OFF with the key inserted into the ignition key cylinder.

   2. Open the driver side door.

      OK:
        Warning buzzer sounds

1. Check the light reminder warning buzzer operation.

   1. Turn the ignition switch OFF.

   2. Set the light control switch to the TAIL or HEAD position.

   3. Open the driver side door.

      OK:
        Warning buzzer sounds

      Result:

        Result | Proceed to
        Key reminder warning buzzer does not sound | A
        Light reminder warning buzzer does not sound | B

| B |

Go to step 5

A |

3.INSPECT UNLOCK WARNING SWITCH ASSEMBLY

1. Remove the unlock warning switch.

1. Measure the resistance of the switch.

   Standard resistance:

     Tester Connection | Condition | Specified Condition
     1 - 2 | Pushed (ON) | Below 1 Ω
     1 - 2 | Not pushed (OFF) | 10 kΩ or higher

| NG |

REPLACE UNLOCK WARNING SWITCH ASSEMBLY

OK |

4.CHECK WIRE HARNESS (UNLOCK WARNING SWITCH - COMBINATION METER AND BODY GROUND)

1. Disconnect the U1 switch connector.

1. Disconnect the C8 meter connector.

1. Measure the resistance of the wire harness side connectors.

   Standard resistance:

     Tester Connection | Specified Condition
     U1-1 - C8-10 | Below 1 Ω
     U1-2 - Body ground | Below 1 Ω

| OK |

Go to step 7

NG |

REPAIR OR REPLACE HARNESS AND CONNECTOR

5.INSPECT HEADLIGHT DIMMER SWITCH ASSEMBLY

1. Remove the headlight dimmer switch.

1. Measure the resistance of the switch.

   Standard resistance:

     LHD
     Tester Connection | Switch Condition | Specified Condition
     13 (B1) - 10 (T1) | HEAD | Below 1 Ω
     13 (B1) - 10 (T1) | TAIL | Below 1 Ω
     13 (B1) - 10 (T1) | OFF | 10 kΩ or higher

   RHD:

     Tester Connection | Switch Condition | Specified Condition
     5 (B1) - 8 (T1) | HEAD | Below 1 Ω
     5 (B1) - 8 (T1) | TAIL | Below 1 Ω
     5 (B1) - 8 (T1) | OFF | 10 kΩ or higher

| NG |

REPLACE HEADLIGHT DIMMER SWITCH ASSEMBLY

OK |

6.CHECK WIRE HARNESS (HEADLIGHT DIMMER SWITCH - COMBINATION METER AND BATTERY)

1. Disconnect the C10 switch connection.

1. Disconnect the C8 meter connection.

1. Measure the voltage of the wire harness side connectors.
