Removal Procedure

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
    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 became un-centered, refer to INFLATABLE RESTRAINT STEERING WHEEL MODULE COIL CENTERING procedure to re-center SIR Coil.
  1. Turn the steering wheel to the straight-ahead position and secure the steering wheel.
  2. Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection .
