Electric Steering with Fail-Safe: No eBay module needed. Pics & Videos !
It has been couple of years since I first posted the Electric Steering idea. My car has progressed far enough and I was ready for it as well so I though I would share the direction I went.
Couple of months ago, I was at my location pic-a-part and ran into a 2010 Toyota Corolla and a 2009 Toyota Prius and I pulled both of them and took a risk. To my amazement, both of these worked on the bench with only the Ignition On, heavy gauge Power and Ground. That's it! 3 wire connection. After further digging and finding the service manuals, I found that these units go in to a Fail-Safe mode and provide steering effort that is just about right when the CAN BUS not present in about 10 seconds. No eBay module needed!
I was not done. I pulled a 2014 Kia Soul EPS, a 2010 Nissan Cube and a 2008 Nissan Versa and all worked in a Fail-Safe mode and without the eBay module. I also pulled a 2007 Toyota Yaris that also works in fail safe mode but requires a VSS signal.
The biggest advantage is obviously they all work in fail safe mode but also they have a remotely mounted ECU that can be unplugged. It's important to get the ECU when pulling the Electric Steering Column.
My testing leads me to believe that just about any Japanese car brand with Electric Steering works in Fail-Safe mode. I did test the Chevy Cobalt and does not work in Fail-Safe just like Saturn Vue even though they are all made by Koyo. For me, I would trust any EPS working in Fail-Safe mode as intended by the manufacture over adding external non-factory module. Lots of testing and development goes on in to these systems.
Below is the list of Car that I know of that has Fail-Safe Electric Steering:
2004-2009 Toyota Prius
2009-2013 Toyota Corolla
2006-2011 Toyota Yaris - (With ABS works in Fail-Safe).
2006-2011 Toyota Yaris - (Non-ABS needs VSS signal or flashing LED)
2007-2009 Nissan Versa
2009-2012 Nissan Cube
2012-2014 Kia Soul
I will be updating this list as I find more information.
