2. Disconnect connector (AB6) from airbag control module, and connect it to test harness B2 connector (8B) terminal.
3. Measure resistance between test harness B2 connector (5B) and test harness C connector (3C) terminals.

CHECK: Connector & terminal
(5B) No.6 - (3C) No.4:
Is resistance less than 10 Ohm?

YES: Go to next

NO: Replace airbag main harness.
