1. CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS  .
   1. Disconnect the A/C control module connector.
   2. Using the tester, measure the resistance between terminals.

      Connector & terminal 

      (i80) No. 2 - (i80) No. 3:

   Is the resistance 400 Ω or more?

   Yes: Related lines between A/C 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 the tester, measure the resistance between terminals.

   Connector & terminal 

   (i80) No. 2 - (i74) No. 3:

   (i80) No. 3 - (i74) No. 2:

   Is the resistance 10 Ω or more?

   Yes: Repair or replace the open circuit of A/C control module related lines.

   No: Check the DTC of A/C control module. Ref. to HVAC SYSTEM (DIAGNOSTICS)>READ DIAGNOSTIC TROUBLE CODE (DTC) .
