1. CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS  .
   1. Disconnect the remote engine start control module connector.
   2. Using a tester, measure the resistance between remote engine start control module connector terminals.

      Connector & terminal 

      Without push button start 

      (B180) No. 1 - (B180) No. 2:

      With push button start 

      (i291) No. 2 - (i291) No. 3:

      Is the resistance 400 Ω or more?

      Yes  : A related line between remote engine start 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  .
   1. Disconnect the audio or navigation unit connector.
   2. Using a tester, measure the resistance between audio or navigation unit connector and remote engine start control module connector.
