DIAGNOSTICS PROCEDURE

Step	Check	Yes	No
1 CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS. Disconnect the A/C control module connector. Using the tester, measure the resistance between terminals. Connector & terminal (i80) No. 2 - No. 3:	Is the resistance 400 Ω or more?	Related lines between A/C control module and main wiring harness is open, or main wiring harness is open at two places or more.	Go to step 2 .
2 CHECK RELATED LINES. Using the tester, measure the resistance between terminals. Connector & terminal (i80) No. 2 - (B40) No. 6: (i80) No. 3 - (B40) No. 14:	Is the resistance 10 Ω or more?	Repair or replace the open circuit of A/C control module related lines.	Check the DTC of A/C control module. < Ref. to READ DIAGNOSTIC TROUBLE CODE (DTC) . >
