Centering



  1. Before servicing the vehicle, refer to the Precautions Section.
    CAUTION
    The new Supplemental Inflatable Restraint (SIR) coil assembly will be centered. Improper alignment of the SIR coil assembly may damage the unit, causing an inflatable restraint malfunction.


    NOTE
    If a double wire harness strap is installed onto the wire harness assembly and column, you must reuse the holder for the wire straps during installation.

  2.  
  3. Remove the wire harness strap(s) where necessary.
