Removal & Installation



  1. Before servicing the vehicle, refer to the Precautions Section.
    NOTE
    When performing service on or near the SRS components, or SRS wiring the SRS must be disabled. Failure to observe the correct procedure could cause deployment of the SRS components. Serious injury can occur.

  2.  
  3. Position the steering wheel so the front wheels are in the straight ahead position.
  4.  
  5. Be sure the ignition switch is in the OFF position.
  6.  
  7. Disconnect the negative battery cable.
    NOTE
    The SDM may have more than one fused power input. To ensure that there is no unwanted SRS deployment, personal injury, or unnecessary SRS 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 will illuminate. This is normal and does not indicate a SRS system malfunction.

  8.  
  9. Locate and remove the fuses supplying power to the SDM.
  10.  
  11. Wait one minute before working on the vehicle.
  12.
