Diagnostic Procedure

  1. Turn ignition switch to LOCK position. Disconnect negative battery cable. Wait at least 90 seconds. Access and disconnect air bag sensor assembly connector C16 (center connector). See AIR BAG SENSOR ASSEMBLY under REMOVAL & INSTALLATION .
  2. Measure resistance between ground and air bag sensor assembly connector C16, terminal No. 19 (circuit Tc, Pink/Black wire). See Figure. If resistance is one megohm or more, replace air bag sensor assembly. If resistance is less than one megohm, replace harness and connector.
