Step	Check	Yes	No
1 CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS. Disconnect the remote engine start CM connector. Using the tester, measure the resistance between terminals. Connector & terminal (B180) No. 2 - No. 3:	Is the resistance 400 Ω or more?	Related lines between remote engine start CM 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 (B280) No. 11 - (B180) No. 2: (B280) No. 21 - (B180) No. 3:	Is the resistance 10 Ω or more?	Repair or replace the open circuit portion of remote engine start CM related lines.	Check that the remote engine start function operates normally.
