1. CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS  .
   1. Disconnect the airbag control module connector.
   2. Using a tester, measure the resistance between terminals in airbag control module connector.
      CAUTION: To measure the voltage and resistance of airbag system component, be sure to use the specified test harness. Ref. to AIRBAG (DIAGNOSTICS)>General Description>PREPARATION TOOL .

      Connector & terminal 

      (AB6) No. 18 - (AB6) No. 19:

      Is the resistance 400 Ω or more?

      Yes  : A related line between airbag 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 steering angle sensor connector.
   2. Using a tester, measure the resistance between the steering angle sensor connector and airbag control module connector.
      CAUTION: To measure the voltage and resistance of airbag system component, be sure to use the specified test harness. Ref. to AIRBAG (DIAGNOSTICS)>General Description>PREPARATION TOOL .
