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.

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 .
  4. Remove the steering column covers and the switch levers. Refer to Turn Signal Multifunction Switch Replacement and to Windshield Wiper and Washer Switch Replacement .

  21. Notice: Once the steering column is removed from the vehicle, the column is extremely susceptible to damage. Dropping the column assembly on the end could collapse the steering shaft or loosen the plastic injections, which maintain column rigidity. Leaning on the column assembly could cause the jacket to bend or deform. Any of the above damage could impair the columns collapsible design. Do NOT hammer on the end of the shaft, because hammering could loosen the plastic injections, which maintain column rigidity. If you need to remove the steering wheel, refer to the Steering Wheel Replacement procedure in this section.

  22. Guide the steering column assembly out of the steering shaft flange and carefully lay down the assembly.
