Code 13

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.
  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 connector (if equipped), accessible through finish plate in glove box. See Figure.
  2. Measure resistance between terminals of spiral cable upper connector. If resistance is less than 1000 ohms, go to step 7). If resistance is 1000 ohms or more, connect a jumper wire between terminals of spiral cable upper connector. Connect a jumper wire between terminals of passenger-side air bag connector (if equipped).
  3. 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.
  4. 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 13 is displayed, replace center air bag sensor. If Code 13 is not displayed, turn ignition switch to LOCK position.
  5. 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 LOCK position. Wait at least 20 seconds. Turn ignition switch to ACC or ON position. Wait at least 20 seconds. Clear codes. See CLEARING CODES  under SELF-DIAGNOSTIC SYSTEM.
  6. 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 13 is displayed, replace steering wheel pad. If Code 13 is not displayed, system is functioning properly at this time. Check for intermittent fault. See AIR BAG WARNING LIGHT INTERMITTENT  under DIAGNOSIS.
  7. Disconnect spiral cable lower connector. Release shorting bar spring in spiral cable lower connector. See RELEASING SHORTING BAR SPRING  under DIAGNOSIS. Measure resistance between terminals of spiral cable upper connector. If resistance is not infinite, replace spiral cable.
  8. If resistance is infinite, disconnect center air bag sensor connector. Release shorting bar spring in center air bag sensor connector. See RELEASING SHORTING BAR SPRING  under DIAGNOSIS.
  9. Measure resistance between terminals of harness side of spiral cable lower connector. If resistance is not infinite, replace harness between center air bag sensor and spiral cable.
  10. If resistance is infinite, reconnect center air bag sensor connector. Measure resistance between terminals of spiral cable lower connector (connector half that leads to center air bag sensor). If resistance is less than 1000 ohms, replace center air bag sensor. If resistance is 1000 ohms or more, system is functioning properly at this time. Check for intermittent fault. See AIR BAG WARNING LIGHT INTERMITTENT  under DIAGNOSIS.
