Disarming the System

Print

Air Bag Fuse Method



  1. Turn the steering wheel so that the vehicles wheels are pointing straight ahead.
  2.  
  3. Place the ignition in the OFF position.
    NOTE
    The sensing and diagnostic module (SDM) may have more than one fused power input. To ensure there is no unwanted SIR deployment, personal injury, or unnecessary SIR system repairs, remove all fuses supplying power to the SDM. With all SDM fuses removed and the ignition switch in the ON position, the AIR BAG warning indicator illuminates. This is normal operation, and does not indicate a SIR system malfunction.

  5. Locate and remove the fuse(s) supplying power to the SDM.
