Code 11

WARNING: This page is about a different car, the 1995 Toyota Paseo. 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. At center air bag sensor connector, measure resistance between terminals +SR and -SR, and terminals +SL and -SL. See Figure. If resistance is not 755-885 ohms, go to step 13).
  3. If resistance is 755-885 ohms, measure resistance between body ground and terminals +SR and +SL of center air bag sensor connector. If resistance is not infinite, replace harness between center air bag sensor and front air bag sensor or repair front air bag sensor connector. See WIRE REPAIR .
  4. If resistance is infinite, measure resistance between body ground and each terminal of spiral cable upper connector. If resistance is not infinite, go to step 15). If resistance is infinite:
    • Go to next step (with passenger-side air bag)
    • Go to step 6) (without passenger-side air bag).
  5. Measure resistance between body ground and each terminal of passenger-side air bag 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.
  6. 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 (if equipped). 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 center air bag sensor.
  8. 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.
  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 steering wheel pad. If Code 11 is not displayed:
    • Go to next step (with passenger-side air bag)
    • Go to step 14) (without passenger-side air bag).
  10. 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.
  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. Use Wiring Check Harness (09843-18020) to connect terminals Tc and E1 of DLC. See Figure.
  12. 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 & TESTING.
  13. Disconnect left front air bag sensor connector. At harness side of left front air bag sensor connector, measure resistance between terminals +S and +A , +S and -S, and -S and -A . See Fig 1. See FRONT AIR BAG SENSOR RESISTANCE table below. Repeat procedure on right front air bag sensor.

    FRONT AIR BAG SENSOR RESISTANCE

    Terminals Resistance (Ohms)
    +S - -A Less Than 1
    +S - -S Greater Than 1,000,000
    +S - -A 755 - 855
  14. 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 or repair front air bag sensor connector. See WIRE REPAIR .
  15. Disconnect spiral cable lower connector. Measure resistance between body ground and each terminal of spiral cable upper connector. If resistance is infinite, replace harness between center air bag sensor and spiral cable. If resistance is not infinite, replace spiral cable.
