    In order to avoid the above conditions, observe the following guidelines:
       • Refer to SRS Component Views in order to determine if you are performing service on or near the SRS components or the SRS wiring.

    3. Important: 

       • Ensure that the coil assembly is centered.
       • The coil assembly becomes uncentered under the following conditions:
          - The steering column is seperated from the steering gear and allowed to rotate.
          - The centering spring is pushed down allowing the hub to rotate while the coil is removed from the steering column.
          - In the event that this occurs, refer to Inflatable Restraint Coil Centering - Off Vehicle (Column Shift and Floor Shift) in Steering Wheel and Column.

    Important: Gently pull on the lower coil assembly wire in order to remove any wire kinks inside of the column assembly. Ensure that there are no kinks or bends in the SRS coil assembly wire. If a kink or a bend is present, interference may occur with the shaft lock mechanism. Turning the steering wheel may cut or damage the wire.
