Disabling Procedure - Air Bag Fuse

WARNING: This page is about a different car, the 2017 Chevrolet Spark. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn the steering wheel so that the vehicles wheels are pointing straight ahead.
  2. Place the ignition in the OFF position.
  3. Locate and remove the fuse(s) supplying power to the Inflatable Restraint Sensing and Diagnostic Module. Refer to SIR Schematics  or Electrical Center Identification Views .
    WARNING: The 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.
  4. Wait 2 minutes before working on the system.
