  1. CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS  .
    1. Turn the ignition switch to OFF.
    2. Disconnect the airbag control module connector.
    3. 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

      (AB42) No. 45 - (AB42) No. 46:

    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 central gateway control module connector.
    2. Using a tester, measure the resistance between airbag control module connector and central gateway control module connector.
