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 

      (L107) No. 2 - (L107) 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 central gateway Control Module connector.
   2. Using a tester, measure the resistance between radar sensor LH connector and central gateway Control Module connector.

      Connector & terminal 

      (L107) No. 2 - (i88) No. 34:

      (L107) No. 7 - (i88) No. 33:

   Is the resistance 10 Ω or more?

   Yes:  Repair or replace the open circuit of the Subaru Rear Vehicle Detection related lines.

   No:  CHECK DTC of radar sensor. Refer to BLIND SPOT DETECTION/REAR CROSS TRAFFIC ALERT (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) .
