Code 11

WARNING: This page is about a different car, the 1994 Lexus LS 400. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: During testing, if codes other than Code 11 are displayed, disregard them.
  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. At center air bag sensor connector (harness side), measure resistance between terminals +SR and -SR and terminals +SL and -SL. See Figure. If resistance is not 755-885 ohms, go to step 21).
  3. If resistance is 755-885 ohms, measure resistance between body ground and terminals +SR and +SL of center air bag sensor connector (harness side). If resistance is infinite, go to next step. If resistance is not infinite, replace harness between center air bag sensor and front air bag sensor.
  4. Measure resistance between body ground and each terminal of spiral cable upper connector (spiral cable side of connector). If resistance is infinite, go to next step. If resistance is not infinite, go to step 23).
  5. Measure resistance between body ground and each terminal of passenger-side air bag connector (harness side). If resistance is infinite, go to next step. If resistance is not infinite, replace harness between center air bag sensor and passenger-side air bag.
  6. Remove cover from seat belt pretensioner check connector located under right rear seat. See Fig 1. Measure resistance between body ground and terminals No. 2, 3, 6 and 7 of seat belt pretensioner check connector. If resistance is infinite, go to next step. If resistance is not infinite, replace harness between seat belt pretensioner check connector and seat belt pretensioner.
  7. Measure resistance between body ground and terminals No. 1, 4, 5 and 8 of seat belt pretensioner check connector. If resistance is infinite, go to next step. If resistance is not infinite, replace harness between seat belt pretensioner check connector and center air bag sensor.
  8. Reconnect center air bag sensor connector. Securely install cover onto seat belt pretensioner check connector. Connect jumper wire between terminals of spiral cable upper connector (spiral cable side of connector). Connect jumper wire between terminals of passenger-side air bag connector (harness side).
  9. Connect jumper wires between terminals of both seat belt pretensioner connectors (harness side). 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.
  10. Turn ignition switch to LOCK position. Wait at least 20 seconds. 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 11 is not displayed, go to next step. If Code 11 is displayed, replace center air bag sensor.
  11. Turn ignition switch to LOCK position. Disconnect negative battery cable. Wait at least 90 seconds. Reconnect spiral cable upper connector. Reconnect negative battery cable. Wait at least 2 seconds.
  12. 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.
  13. Connect jumper wire between terminals Tc and E1 of DLC. See Figure. If Code 11 is not displayed, go to next step. If Code 11 is displayed, replace steering wheel pad.
  14. Turn ignition switch to LOCK position. Disconnect negative battery cable. Wait at least 90 seconds. Reconnect passenger-side air bag connector. Reconnect negative battery cable. Wait at least 2 seconds. Turn ignition switch to ACC or ON position. Wait at least 20 seconds.
  15. 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. Connect jumper wire between terminals Tc and E1 of DLC. See Figure. If Code 11 is not displayed, go to next step. If Code 11 is displayed, replace passenger-side air bag.
  16. Turn ignition switch to LOCK position. Disconnect negative battery cable. Wait at least 90 seconds. Reconnect left seat belt pretensioner connector. Securely install cover onto seat belt pretensioner check connector. Reconnect center air bag sensor connector.
  17. 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. Turn ignition switch to ACC or ON position. Wait at least 20 seconds.
  18. Connect jumper wire between terminals Tc and E1 of DLC. See Figure. If Code 11 is not displayed, go to next step. If Code 11 is displayed, replace left seat belt pretensioner.
  19. Turn ignition switch to LOCK position. Disconnect negative battery cable. Wait at least 90 seconds. Reconnect right seat belt pretensioner connector. 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.
  20. Turn ignition switch to LOCK position. Wait at least 20 seconds. 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 11 is displayed, replace right seat belt pretensioner. If Code 11 is not displayed, check for intermittent fault. See AIR BAG WARNING LIGHT INTERMITTENT  under DIAGNOSIS & TESTING.
  21. Disconnect left front air bag sensor connector. At left front air bag sensor connector, measure resistance between terminals +S and +A (755-885 ohms), +S and -S (infinite ohms), and -S and -A (less than one ohm). See Figure. Repeat procedure on right front air bag sensor.
  22. If resistance is not as specified, replace front air bag sensor. If resistance is as specified, replace harness between center air bag sensor and front air bag sensor.
  23. Disconnect spiral cable lower connector. Measure resistance between body ground and each terminal of spiral cable upper connector (spiral cable side of connector). If resistance is infinite, replace harness between center air bag sensor and spiral cable. If resistance is not infinite, replace spiral cable.
