Issues with DPS. Coupler failed. Advice welcome.

This is my first post to this forum. I have a 2013 Commander 800 DPS. I am starting to have wear and tear issues and have found this forum to be helpful in the past so I thought I would join and ask for some advice. A few weeks back, I noticed my DPS steering was beginning to be sluggish. As if it was not responding at certain positions while turning like it was sticking somewhere. I road it for a few more hours and then my steering went out completely! Lucky it was at a slow speed and I was not hurt or killed. I see an impending lawsuit with this issue for sure. Eventually I have discovered that the coupling joint between the rack and pinion and the DPS unit had failed. The splines wore out and had slipped. So, I removed the rack and pinion and the DPS motor to get the coupling off. However, after I removed the rack and pinion but before removed the dps motor, I started the bike and noticed that the steering still had binding points in it. This did not make sense to me since there was no pressure from the rack and pinion on the motor. Regardless, I have to replace the coupler and I have ordered it but my question is, why would I still get this sluggish reaction from the DPS unit? When I removed it the motor would turn freely using my hand so there is no bearing issue. Could it need to be reset? Will it reset just by me disconnecting it from the electrical system when I removed it? Would like to hear suggestions. Thamks.
