      20 (H) - 12 (EL) Light control switch off 10 kΩ or higher
      18 (T) - 12 (EL)
      18 (T) - 12 (EL) Light control switch tail Below 1 Ω
      18 (T) - 12 (EL) Light control switch head Below 1 Ω
      20 (H) - 12 (EL)

    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      17 (HF) - 12 (EL) Headlight dimmer switch flash Below 1 Ω

      14 (CR) - 12 (EL) Turn signal switch neutral 10 kΩ or higher
      13 (TR) - 12 (EL)
      15 (TL) - 12 (EL)
      15 (TL) - 12 (EL) Turn signal switch left lane change Below 1 Ω
      14 (CR) - 12 (EL) Turn signal switch left turn Below 1 Ω
      15 (TL) - 12 (EL)

    4. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Switch 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

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