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

      Connector & terminal 

      (i105) No. 7 - (i105) No. 17:

   Is the resistance 400 Ω or more?

   Yes:  A related line between DCM 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 DCM connector and audio or central gateway Control Module connector.

      Connector & terminal 

      (i105) No. 7 - (i88) No. 13:

      (i105) No. 17 - (i88) No. 12:

   Is the resistance 10 Ω or more?

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

   No:  CHECK DTC of the telematics. Refer to TELEMATICS SYSTEM (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) .
