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

      Connector and terminal 

      (i87) No. 3 - (i87) No. 4:

      Is the resistance 400 Ω or more?

      Yes  : A related line between Driver Monitoring Unit 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 Driver Monitoring Unit connector and central gateway control module connector.

      Connector and terminal 

      (i87) No. 3 - (i88) No. 5:

      (i87) No. 4 - (i88) No. 6:

      Is the resistance 10 Ω or more?

      Yes  : Repair or replace the open circuit of Driver Monitoring Unit related lines.

      No  : Check DTC of Driver Monitoring Unit. Ref. to DRIVER MONITOR (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) .
