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

      Connector & terminal 

      (R25) No. 2 - (R25) No. 7:

   Is the resistance 400 Ω or more?

   Yes  : A related line between radar sensor LH 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 steering sensor connector.
   2. Using a tester, measure the resistance between the radar sensor LH connector and steering sensor connector.

      Connector & terminal 

      (R25) No. 2 - (i74) No. 3:

      (R25) No. 7 - (i74) No. 2:

   Is the resistance 10 Ω or more?

   Yes  : Repair or replace the open circuit of the Blind Spot Detection/Rear Cross Traffic Alert related lines.

   No  : The communication harness is normal. Check DTC of radar sensor. Ref. to BLIND SPOT DETECTION/REAR CROSS TRAFFIC ALERT (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) .
