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 

      (B150) No. 15 - (B150) 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 audio or navigation unit connector.
   2. Using a tester, measure the resistance between audio or navigation unit connector and auto headlight beam leveler control module connector.
