Step	Check	Yes	No
1 CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS. Disconnect the power steering Control Module connector. Using the tester, measure the resistance between terminals. Connector & terminal (B450) No. 9 - No. 10:	Is the resistance 400 Ω or more?	Related lines or main wiring harness between power steering Control Module and 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 (B450) No. 9 - (B40) No. 6: (B450) No. 10 - (B40) No. 14:	Is the resistance 10 Ω or more?	Repair or replace the open circuit portion of power steering Control Module related lines.	Check DTC of power steering Control Module. <Ref. to OPERATION , Read Diagnostic Trouble Code (DTC).>
