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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition 11 (H) - 12 (A) - 13 (T) - 19 (EL) Light control switch OFF 10 kΩ or higher 13 (T) - 19 (EL) Light control switch TAIL Below 1 Ω 11 (H) - 13 (T) - 19 (EL) Light control switch HEAD Below 1 Ω 12 (A) - 19 (EL) Light control switch AUTO Below 1 Ω

      
      

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

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition 14 (HF) - 19 (EL) Headlight dimmer switch FLASH Below 1 Ω 15 (HL) - 19 (EL) Headlight dimmer switch LOW BEAM Below 1 Ω 19 (EL) -20 (HU) Headlight dimmer switch HIGH BEAM Below 1 Ω

      
      

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

      Tech Tips

      Perform the "LOW BEAM" and "HIGH BEAM" inspection with the light control switch on "HEAD".

3. Check the turn signal switch.
