  3. If resistance is less than 10 ohms, check resistance between ground and terminal No. 5 at connector 5A of test harness "A". If resistance is less than 10 k/ohms, replace air bag main wiring harness. If resistance is more than 10 k/ohms, check resistance between ground and terminal No. 5 at connector 5B of test harness "B".
