  2. Measure resistance between ground and terminal No. 17 and 18 at connector 5A of test harness "B2". If resistance is less than 10 ohms at both terminals, go to next step. If resistance is more than 10 ohms at any terminal, repair body grounding circuit.
  3. Connect connectors AB1 and B31. Disconnect 12-pin Yellow AB6 from air bag control unit. Connect connector AB6 to connector 8B of test harness "B2". See Figure . Measure resistance between ground and terminal No. 11 at connector 5B of test harness "B2". If resistance is more than 10 ohms, replace air bag main wiring harness. If resistance is less than 10 ohms, measure resistance between ground and terminal No 12 at connector 5B of test harness "B2". If resistance is more than 10 ohms, replace air bag main wiring harness. If resistance is less than 10 ohms, replace air bag control unit. See CONTROL UNIT  under REMOVAL & INSTALLATION.
