  4. Measure resistance between ground and BOB test pin No. 3. If resistance is infinite, go to next step. If resistance is not infinite, repair or replace Yellow-Red wire between air bag control module connector and passenger-side air bag module harness connector. See WIRING DIAGRAMS . Go to step  6.
