      1 (HU) - 12 (EL) Dimmer switch in high position Below 1 Ω
      Fog Light Switch
      Tester Connection Condition Specified Condition
      4 (BFG) - 12 (EL)*2 Fog light switch in front position Below 1 Ω
      13 (B) - 12 (EL)*3 Fog light switch in rear position Below 1 Ω
      Turn Signal Switch
      Tester Connection Condition Specified Condition
      9 (TR) - 12 (EL) Turn signal switch in neutral position 10 kΩ or higher
      3 (TL) - 12 (EL) Turn signal switch in neutral position 10 kΩ or higher
      9 (TR) - 12 (EL) Turn signal switch in right turn position Below 1 Ω
      9 (TR) - 12 (EL) Turn signal switch in full right turn position Below 1 Ω
      9 (TR) - 11 (CR) Turn signal switch in full right turn position Below 1 Ω
      11 (CR) - 12 (EL) Turn signal switch in full right turn position Below 1 Ω
      3 (TL) - 12 (EL) Turn signal switch in left turn position Below 1 Ω
      3 (TL) - 12 (EL) Turn signal switch in full left turn position Below 1 Ω
      3 (TL) - 11 (CR) Turn signal switch in full left turn position Below 1 Ω
      11 (CR) - 12 (EL) Turn signal switch in full left turn position Below 1 Ω

      • *1: w/ Light Control Switch off Position

      • *2: w/ Front Fog Light

      • *3: w/ Rear Fog Light

      Tech Tips


      • The left turn or right turn condition indicates a condition in which the turn signal switch will return to the neutral position after releasing your hand from the turn signal switch (turn signal switch is operated approximately 7°).

      • The full left turn or full right turn condition indicates a condition in which the turn signal switch will not return to the neutral position after releasing your hand from the turn signal switch (turn signal switch is operated 12°).

      If the result is not as specified, replace the turn signal switch.
