Steering Column Replacement Notchback

Important: Remove the steering column only if:

   • The steering column requires replacement.
   • The steering and the ignition lock housing require replacement.
   • Another operation requires the removal of the steering column.

Removal Procedure

    Notice: Refer to Steering Column in Lock Position Notice in the Preface section.

    Important: Ensure the front wheels are in the straight-ahead position.

  1. Adjust the steering wheel to the straight-ahead position.
  2. Caution: The sensing and the diagnosis module (SDM) can maintain sufficient voltage to deploy the airbags and pretensioners for up to 1 minute after the ignition has been turned OFF and the fuse has been removed. If the airbags and pretensioners are not disconnected, do not begin service until one minute has been passed after disconnecting power to the SDM. Failure to do so may cause personal injury.

  3. Disconnect the negative battery cable and let the vehicle sit for 1 minute. Refer to Battery Negative Cable Disconnection and Connection.
