Code 11

WARNING: This page is about a different car, the 1995 Toyota Tercel. 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 (if equipped), accessible through finish plate in glove box. See Figure.
  2. Disconnect center air bag sensor connector. Measure resistance between body ground and each terminal of spiral cable upper connector. If resistance is infinite, go to next step. If resistance is not infinite, go to step 10).
  3. Measure resistance between body ground and each terminal of passenger-side air bag harness connector. 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.
  4. Reconnect center air bag sensor connector. Connect jumper wire between terminals of spiral cable upper connector. Connect jumper wire between terminals of 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.
  5. 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. Use Wiring Check Harness (09843-18020) to connect terminals Tc and E1 of DLC. See Figure. If Code 11 is displayed, replace center air bag sensor.
  6. If Code 11 is not displayed, 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.
  7. 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. Use Wiring Check Harness (09843-18020) to connect terminals Tc and E1 of DLC. See Figure. If Code 11 is displayed, replace steering wheel pad.
  8. Turn ignition switch to LOCK position. Disconnect negative battery cable. Wait at least 20 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.
  9. 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. Use Wiring Check Harness (09843-18020) to connect terminals Tc and E1 of DLC. See Figure. If Code 11 is displayed, replace passenger-side air bag. If Code 11 is not displayed, system is functioning properly at this time. Check for intermittent fault. See AIR BAG WARNING LIGHT INTERMITTENT  under DIAGNOSIS.
  10. Disconnect spiral cable lower connector. Measure resistance between each terminal of spiral cable upper connector and body ground. If resistance is infinite, replace wiring harness between spiral cable and center air bag sensor. If resistance is not infinite, replace spiral cable.
