Diagnostic Procedure

  1. Disable air bag system. See DISABLING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM.
  2. Measure resistance between ground and upper spiral cable connector Yellow-Black wire (circuit D+) and Yellow wire (circuit D-) individually. See WIRING DIAGRAMS . If resistance is more than one megohm, go to next step. If resistance is less than one megohm, go to step  7.
  3. Measure resistance between ground and passenger-side air bag module connector Yellow-Red wire (circuit P+) and Yellow-Green wire (circuit D-) individually. See WIRING DIAGRAMS . If resistance is more than one megohm, go to next step. If resistance is less than one megohm, repair or replace harness or connector between air bag sensor assembly and passenger-side air bag module.
  4. Reconnect air bag sensor assembly connector C21 (center connector). Connect jumper wire between upper spiral cable connector Yellow-Black wire (circuit D+) and Yellow wire (circuit D-). Connect jumper wire between passenger-side air bag module harness connector Yellow-Red wire (circuit P+) and Yellow-Green wire (circuit D-). Connect negative battery cable. Wait at least 2 seconds. Turn ignition switch to ACC or 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. Turn ignition switch to ACC or ON position. Wait at least 20 seconds. Retrieve DTCs. See RETRIEVING CODES  under DIAGNOSTICS. If DTC 11-B0102 is displayed, replace air bag sensor assembly. If DTC 11-B0102 is not displayed, go to next step.
  5. Turn ignition switch to LOCK position. Disconnect negative battery cable. Wait at least 90 seconds. Reconnect upper spiral cable connector (to driver-side air bag module). Leave jumper wire between passenger-side air bag module harness connector connected. Reconnect negative battery cable. Wait at least 2 seconds. Turn ignition switch to ACC or 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. Turn ignition switch to ACC or ON position. Wait at least 20 seconds. Retrieve codes. See RETRIEVING CODES  under DIAGNOSTICS. If DTC 11-B0102 is displayed, replace driver-side air bag module. If DTC 11-B0102 is not displayed, go to next step.
  6. Turn ignition switch to LOCK position. Disconnect negative battery cable. Wait at least 90 seconds. Reconnect driver-side air bag module connector. Reconnect negative battery cable. Wait at least 2 seconds. Turn ignition switch to ACC or 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. Turn ignition switch to ACC or ON position. Wait at least 20 seconds. Retrieve codes. See RETRIEVING CODES  under DIAGNOSTICS. If DTC 11-B0102 is displayed, replace passenger-side air bag module. If DTC 11-B0102 is not displayed, system is functioning properly at this time. Check for intermittent fault. See AIR BAG WARNING LIGHT INTERMITTENT .
  7. Disconnect spiral cable lower connector. Measure resistance between ground and upper spiral cable connector Yellow-Black wire (circuit D+). If resistance is more than one megohm, go to next step. If resistance is less than one megohm, replace spiral cable.
  8. Measure resistance between ground and Yellow-Black wire (circuit D+) of air bag sensor assembly side of upper spiral cable connector. If resistance is less than one megohm, replace wiring harness between spiral cable and air bag sensor assembly. If resistance is more than one megohm, system is functioning properly at this time. Check for intermittent fault. See AIR BAG WARNING LIGHT INTERMITTENT .
