1. INSPECT HEADLIGHT DIMMER SWITCH ASSEMBLY (for LHD)

1. Measure the resistance of the switch.

   Standard resistance (Light control switch):

     Tester Connection | Switch Condition | Specified Condition
     13 (B1) - 10 (T1) | OFF | 10 kΩ or higher
     12 (RF) - 11 (ED) | OFF | 10 kΩ or higher
     13 (B1) - 10 (T1) | TAIL | Below 1 Ω
     13 (B1) - 10 (T1) | HEAD | Below 1 Ω
     12 (RF) - 11 (ED) | HEAD | Below 1 Ω

   Standard resistance (Headlight dimmer switch):

     Tester Connection | Switch Condition | Specified Condition
     11 (ED) - 9 (HU) | FLASH | Below 1 Ω
     11 (ED) - 8 (HL) | FLASH | Below 1 Ω
     11 (ED) - 8 (HL) | LO BEAM | Below 1 Ω
     11 (ED) - 9 (HU) | HI BEAM | Below 1 Ω
     11 (ED) - 8 (HL) | HI BEAM | Below 1 Ω

   Standard resistance (Turn signal switch):

     Tester Connection | Switch Condition | Specified Condition
     7 (E) - 6 (TR) | Right turn | Below 1 Ω
     7 (E) - 5 (TL) | Neutral | 10 kΩ or higher
     7 (E) - 6 (TR) | Neutral | 10 kΩ or higher
     7 (E) - 5 (TL) | Left turn | Below 1 Ω

   If the result is not as specified, replace the dimmer switch assembly.

2. INSPECT HEADLIGHT DIMMER SWITCH ASSEMBLY (for RHD)

1. Measure the resistance of the switch.

   Standard resistance (Light control switch):

     Tester Connection | Switch Condition | Specified Condition
     5 (B1) - 8 (T1) | OFF | 10 kΩ or higher
     6 (RF) - 7 (ED) | OFF | 10 kΩ or higher
     5 (B1) - 8 (T1) | TAIL | Below 1 Ω
     5 (B1) - 8 (T1) | HEAD | Below 1 Ω
     6 (RF) - 7 (ED) | HEAD | Below 1 Ω

   Standard resistance (Headlight dimmer switch):

     Tester Connection | Switch Condition | Specified Condition
     7 (ED) - 9 (HU) | FLASH | Below 1 Ω
     7 (ED) - 10 (HL) | FLASH | Below 1 Ω
     7 (ED) - 10 (HL) | LO BEAM | Below 1 Ω
     7 (ED) - 9 (HU) | HI BEAM | Below 1 Ω
     7 (ED) - 10 (HL) | HI BEAM | Below 1 Ω

   Standard resistance (Turn signal switch):

     Tester Connection | Switch Condition | Specified Condition
     11 (E) - 13 (TR) | Right turn | Below 1 Ω
     11 (E) - 12 (TL) | Neutral | 10 kΩ or higher
     11 (E) - 13 (TR) | Neutral | 10 kΩ or higher
     11 (E) - 12 (TL) | Left turn | Below 1 Ω

   If the result is not as specified, replace the dimmer switch assembly.
