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 and terminal 

   (AB6) No. 13 - (AB6) No. 22:

   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 sensor connector.
   2. Using a tester, measure the resistance between the steering 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 .

   Connector and terminal 

   (AB6) No. 13 - (i74) No. 3:

   (AB6) No. 22 - (i74) No. 2:

   Is the resistance 10 Ω or more?

   Yes:  Repair or replace the open circuit portion of airbag control module related lines.

   No:  Check DTC of airbag control module. Ref. to AIRBAG (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) .
