Issue / Concern

My steering suddenly got very heavy while pulling into a parking spot today, and the Service StabiliTrak message popped up on the DIC. I checked the fluid level but then remembered this is an Electric Power Steering rack. I'm getting a C0450 code on my scan tool and I can't clear it.

Checked the 125A mega fuse on top of the battery and cleaned the main chassis ground under the driver side door.
