Code 11

WARNING: This page is about a different car, the 1995 Lexus SC 400 and 1995 Lexus SC 300. 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.
  2. Disconnect center air bag sensor connector. At center air bag sensor connector (harness side), measure resistance between terminals 2 (+SR) and 1 (-SR) and terminals 1 (+SL) and 2 (-SL). If resistance is not 755-885 ohms, go to step 12).
  3. If resistance is 755-885 ohms, measure resistance between body ground and terminals 2 (+SR) and 1 (+SL) of center air bag sensor connector (harness side). See Figure. If resistance is infinite, go to next step. If resistance is not infinite, repair or replace wiring 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 14).
  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 wiring harness between center air bag sensor and passenger-side air bag.
  6. Reconnect center air bag sensor connector. Connect jumper wire between terminals of spiral cable upper connector and passenger-side air bag connector (harness side of each connector). Reconnect negative battery cable. Wait at least 2 seconds.
  7. Turn ignition switch to ACC or ON position. Wait at least 20 seconds. Connect jumper wire between terminals 7 (Tc) and 5 (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.
  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. Turn ignition switch to ACC or ON position. Wait at least 20 seconds. Clear codes. See CLEARING CODES  under SELF-DIAGNOSTIC SYSTEM.
  9. 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 7 (Tc) and 5 (E1) of DLC. See Figure. If Code 11 is not displayed, go to next step. If Code 11 is displayed, replace steering wheel pad.
  10. Turn ignition switch to LOCK position. Disconnect negative battery cable. Wait at least 20 seconds. Reconnect passenger-side air bag connector. Disconnect spiral cable upper connector. Reconnect negative battery cable. Wait at least 2 seconds. Turn ignition switch to ACC or ON position. Wait at least 20 seconds.
  11. 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 7 (Tc) and 5 (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.
  12. Disconnect left front air bag sensor connector. At left front air bag sensor connector (sensor side), 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.
  13. If resistance is not to specification, replace front air bag sensor. If resistance is okay, replace harness between center air bag sensor and front air bag sensor.
  14. 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.
