If resistance is more than one ohm, repair or replace harness or connector between right-side air bag squib harness connector and air bag sensor assembly.
  3. Reconnect air bag sensor assembly connector C8 to air bag sensor assembly. See Figure. Connect jumper wire between Yellow/Red wire (circuit SFR+) and Yellow/Green wire (circuit SFR-) of right-side air bag squib harness connector. Connect negative battery cable. Wait at least 2 seconds. Turn ignition switch to ON position. Wait at least 20 seconds. Clear DTCs. See CLEARING CODES  under DIAGNOSTICS. Turn ignition switch to LOCK position. Wait at least 20 seconds.
