1. CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS  .
   1. Disconnect the auto headlight beam leveler Control Module connector.
   2. Using a tester, measure the resistance between the auto headlight beam leveler Control Module connector terminals.

      Connector & terminal 

      (B78) No. 15 - (B78) No. 16:

   Is the resistance 400 Ω or more?

   Yes:  A related line between auto headlight beam leveler Control Module and main wiring harness is open, or main wiring harness is open at two places or more.

   No:  Go to  2.

2. CHECK RELATED LINES  .
   1. Disconnect the central gateway Control Module connector.
   2. Using a tester, measure the resistance between auto headlight beam leveler Control Module connector and central gateway Control Module connector.
