         Dimmer Switch Tester Connection Condition Specified Condition 11 (HU) - 12 (EL) Dimmer switch in low position 10 kΩ or higher 11 (HU) - 12 (EL) Dimmer switch in high position Below 1 Ω 11 (HU) - 12 (EL) Dimmer switch in high flasher position Below 1 Ω 17 (HF) - 12 (EL) Below 1 Ω
         Turn Signal Switch Tester Connection Condition Specified Condition 13 (TR) - 12 (EL) Right turn Below 1 Ω 13 (TR) - 12 (EL) Neutral 10 kΩ or higher 15 (TL) - 12 (EL) Neutral 10 kΩ or higher 15 (TL) - 12 (EL) Left turn Below 1 Ω
         Front Fog Light Switch*2 Tester Connection Condition Specified Condition 4 (BFG) - 3 (LFG) Front fog light switch off 10 kΩ or higher 4 (BFG) - 3 (LFG) Front fog light switch on Below 1 Ω
         Rear Fog Light Switch Tester Connection Condition Specified Condition 2 (B) - 3 (LFG) Rear fog light switch off 10 kΩ or higher 2 (B) - 3 (LFG) Rear fog light switch on Below 1 Ω

         
         

         • *1: w/ Automatic Light Control

         • *2: w/ Front Fog Light

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