1. CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS  .
   1. Disconnect the MFD connector.
   2. Using a tester, measure the resistance between terminals in MFD connector.

      Connector & terminal 

      (i122) No. 19 - (i122) No. 20:

   Is the resistance 400 Ω or more?

   Yes  : Related lines between MFD 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  .

   Using a tester, measure the resistance between MFD connector and audio or navigation unit connector.

   Connector & terminal 

   (i122) No. 19 - (i87) No. 9:

   (i122) No. 20 - (i87) No. 10:

   Is the resistance 10 Ω or more?

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

   No  : The communication harness is normal. Check DTC of MFD. Ref. to MULTI-FUNCTION DISPLAY (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) .
