   *a	Component without harness connected (Headlight leveling switch)
   *b	Battery

   
   

   1. Check the ratio.

      
      

      1. Remove the head light leveling switch assembly.

      2. Connect the positive (+) battery lead to terminal 1 and the negative (-) battery lead to terminal 4.

      3. Check the ratio which is obtained by dividing the voltage between terminals 2 and 4 by the voltage between 1 and 4. The voltages must be measured using a voltmeter.

         Standard Ratio
         Tester Connection Switch Condition Specified Condition 1 (B) - 4 (E) 2 (T) - 4 (E) 0 0.87 to 0.93 1 (B) - 4 (E) 2 (T) - 4 (E) 1 0.76 to 0.82 1 (B) - 4 (E) 2 (T) - 4 (E) 2 0.66 to 0.72 1 (B) - 4 (E) 2 (T) - 4 (E) 3 0.55 to 0.61 1 (B) - 4 (E) 2 (T) - 4 (E) 4 0.44 to 0.50 1 (B) - 4 (E) 2 (T) - 4 (E) 5 0.34 to 0.40

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

   2. Check the illumination operation.

         Apply battery voltage to the head light leveling switch assembly connector.

         Standard
         Tester Connection Specified Condition Battery positive (+) →Terminal 3 (ILL+) Battery positive (-) →Terminal 4 (E) The illumination comes on

         If the illumination does not illuminate, replace the headlight leveling switch.
