Removal Procedure

Important:  If the steering column connectors are disconnected with the ignition in the ON position, the BCM will enter a fail enable mode and prevent steering column lock operation. The PCM will also inhibit vehicle motion by disabling fuel. To clear the BCM fail enable mode, disconnect the BCM fuse #25 for 15 seconds.

1. Disable the SIR system. Refer to DISABLING SYSTEM .
2. Turn the steering wheel far enough to the left to gain access to the upper coupling bolt.
