1. CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS  .
   1. Disconnect the seat ventilation Control Module connector.
   2. Using a tester, measure the resistance between the seat ventilation Control Module connector terminals.

      Connector & terminal 

      (St41) No. 9 - (St41) No. 10:

   Is the resistance 400 Ω or more?

   Yes:  A related line between seat ventilation Control Module 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  .

   Using a tester, measure the resistance between seat ventilation Control Module connector and central gateway Control Module connector.

   Connector & terminal 

   (St41) No. 9 - (i88) No. 6:

   (St41) No. 10 - (i88) No. 5:

   Is the resistance 10 Ω or more?

   Yes:  Repair or replace the open circuit of seat ventilation related lines.

   No:  CHECK DTC of ventilation seat system. Refer to VENTILATION SEAT (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) .
