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.

  (i270) No. 7 - No. 17: (MAIN-CAN)
  
  (i270) No. 6 - No. 16: (BODY-CAN)
  
  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.
CHECK RELATED LINES .
1. Disconnect the steering angle sensor connector. (MAIN-CAN)
2. Disconnect the audio or navigation unit connector. (BODY-CAN)
3. Using the tester, measure the resistance between terminals.

  Is the resistance 10 Ω or more?
  
  Yes : Repair or replace the open circuit of telematics system related lines.
  
  No : The communication harness is normal. Check DTC of the telematics. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) .
