  8. Ensure the steering wheel and the front wheels are in the straight ahead position.
    1. With foot OFF the brake pedal and the shift lever in the PARK position put the vehicle in the accessory mode. This will unlock the steering column for 5 minutes.
    2. Turn the steering wheel to verify the steering column is NOT locked.
    3. Disconnect the steering column lock control module electrical connectors.
    4. With foot OFF the brake pedal and the shift lever in the PARK position, press the ignition and start switch once. This will place the ignition system in the OFF mode and leave the steering column unlocked as long as the electrical connectors are disconnected.
  9. CAUTION:

    With wheels of the vehicle facing straight ahead, secure the steering wheel utilizing steering column anti-rotation pin, steering column lock, or a strap to prevent rotation. Locking of the steering column will prevent damage and a possible malfunction of the SIR system. The steering wheel must be secured in position before disconnecting the following components:

    • The steering column
    • The intermediate shaft(s)
    • The steering gear

    After disconnecting these components, do not rotate the steering wheel or move the front tires and wheels. Failure to follow this procedure may cause the SIR coil assembly to become un-centered and cause possible damage to the SIR coil. If you think the SIR coil has become un-centered, refer to your specific SIR coil's centering procedure to re-center SIR Coil.

  10. If replacing the steering column, verify the front wheels are in the straight ahead position and LOCK the steering column using the lock pin from the NEW steering column.
  11. If removing and reinstalling the steering column, verify the front wheels are in the straight ahead position and SECURE the steering column as best as possible to prevent any rotation of the steering column shaft and steering wheel.
  12. Place match marks on the steering gear shaft and the intermediate steering shaft to aid in installation.
  13. Upper Intermediate Steering Shaft Bolt (1) - Remove

  18. CAUTION:

    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.

  19. Steering Column (2) - Remove
  20. If replacing the steering column, transfer components as necessary.
  21. If replacing the steering column, copy the match marks from the OLD steering column to the NEW steering column.
