1. CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS  .
   1. Disconnect the audio or navigation unit connector.
   2. Using a tester, measure the resistance between audio or navigation unit connector terminals.

      Connector and terminal 

      (i87) No. 9 - (i87) No. 10:

   Is the resistance 400 Ω or more?

   Yes:  A related line between the navigation unit and the 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 body integrated unit connector.
   2. Using a tester, measure the resistance between audio or navigation unit connector and body integrated unit.

      Connector and terminal 

      (i87) No. 9 - (B281) No. 17:

      (i87) No. 10 - (B281) No. 19:

   Is the resistance 10 Ω or more?

   Yes:  Repair or replace the open circuit of infotainment system related lines.
