  1. Disconnect negative battery cable. Wait at least 90 seconds. Remove steering wheel pad. See STEERING WHEEL PAD & SPIRAL CABLE  under REMOVAL & INSTALLATION. Disconnect passenger-side air bag harness connector, accessible through finish plate in glove box. See Figure. Disconnect seat belt pretensioner connectors.
  2. Disconnect center air bag sensor connector. Measure resistance between terminals of spiral cable upper connector (spiral cable side of connector). If resistance is less than one ohm, go to step 5). If resistance is more than one ohm, go to next step.
  3. Disconnect spiral cable lower connector. Measure resistance between terminals of spiral cable upper connector (spiral cable side of connector). If resistance is less than one ohm, go to next step. If resistance is one ohm or more, replace spiral cable.
  4. Measure resistance between terminals of spiral cable lower connector (center air bag sensor side of connector). If resistance is less than one ohm, go to next step. If resistance is more than one ohm, replace harness between center air bag sensor and spiral cable.
  5. Reconnect center air bag sensor connector. Reconnect spiral cable lower connector. Connect jumper wire between terminals of spiral cable upper connector, passenger-side air bag connector and both seat belt pretensioner connectors (harness side of each connector).
  6. Reconnect negative battery cable. Wait at least 2 seconds. Turn ignition switch to ACC or ON position. Wait at least 20 seconds. Clear codes. See CLEARING CODES  under SELF-DIAGNOSTIC SYSTEM. Turn ignition switch to LOCK position. Wait at least 20 seconds.
  7. Turn ignition switch to ACC or ON position. Wait at least 20 seconds. Connect jumper wire between terminals Tc and E1 of DLC. See Figure. If Code 14 is not displayed, go to next step. If Code 14 is displayed, replace center air bag sensor.
  8. Turn ignition switch to LOCK position. Disconnect negative battery cable. Wait at least 90 seconds. Reconnect spiral cable upper connector (steering wheel pad). Reconnect negative battery cable. Wait at least 2 seconds.
  9. Turn ignition switch to ACC or ON position. Wait at least 20 seconds. Clear codes. See CLEARING CODES  under SELF-DIAGNOSTIC SYSTEM. Turn ignition switch to LOCK position. Wait at least 20 seconds. Turn ignition switch to ACC or ON position. Wait at least 20 seconds.
  10. Connect jumper wire between terminals Tc and E1 of DLC. See Figure. If Code 14 is displayed, replace steering wheel pad. If Code 14 is not displayed, check for intermittent fault. See AIR BAG WARNING LIGHT INTERMITTENT  under DIAGNOSIS & TESTING.
