Code 15

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.
  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. Disconnect center air bag sensor connector. At center air bag sensor connector, measure resistance between terminals +SR and -SR, and between terminals +SL and -SL. See Figure. If resistance is not 755-885 ohms, go to step 7). If resistance is 755-885 ohms:
    • Go to step 4)
  3. Reconnect negative battery cable. Turn ignition switch to ON position. Measure voltage between body ground and terminals +SR and +SL of center air bag sensor connector. If voltage is one volt or more, replace harness between center air bag sensor and front air bag sensor or repair front air bag sensor connector. See WIRE REPAIR . If voltage is less than one volt, go to next step.
  4. Turn ignition switch to LOCK position. Disconnect negative battery cable. Reconnect center air bag sensor connector. 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).
  5. 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.
  6. Use Wiring Check Harness (09843-18020) to connect terminals Tc and E1 of DLC. See Figure. If Code 15 is displayed, replace center air bag sensor. If Code 15 is not displayed, system is functioning properly at this time. Check for intermittent fault. See AIR BAG WARNING LIGHT INTERMITTENT  under DIAGNOSIS & TESTING.
  7. Disconnect left front air bag sensor connector. At left front air bag sensor connector (connector half that leads to front air bag sensor), measure resistance between terminals +S and +A , +S and -S, and -S and -A . See Figure. See FRONT AIR BAG SENSOR RESISTANCE table below. Repeat procedure on right front air bag sensor. If resistances are not as specified, replace 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
  8. If resistances are okay, disconnect center air bag sensor connector. At center air bag sensor connector, connect a jumper wire between terminals +SR and -SR, and another jumper wire between terminals +SL and -SL.
  9. At front air bag sensor connector (connector half that leads to front air bag sensor), measure resistance between terminals +SR and -SR (right sensor), and between terminals +SL and -SL (left sensor).
  10. If resistance is less than one ohm, replace front air bag sensor connector. See WIRE REPAIR . If resistance is one ohm or more, replace harness between center air bag sensor and front air bag sensor or repair front air bag sensor connector. See WIRE REPAIR .
