1. CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS. 
   1. Disconnect the impact sensor connector.
   2. Using the tester, measure the resistance between terminals.

      Connector & terminal 

      (B367) No. 5 - No. 6:

   Is the resistance 400 Ω or more?

   • Yes  : Related lines between the impact sensor 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 

   (B367) No. 6 - (B40) No. 14:

   (B367) No. 5 - (B40) No. 6:

   Is the resistance 10 Ω or more?

   • Yes  : Repair or replace the open circuit of the impact sensor system related lines.
   • No  : The communication harness is normal. Check the impact sensor.
