It has been a while since I posted on this forum. I am not making or selling anything. I have posted this on couple of other forums and this is not for everyone.
Some of you have manual steering and I though you might like to see how added electric assisted power steering in my 1964 Falcon. Some of you may have come across the Saturn Vue conversions but I think I have found even cheaper and better alternative with no caster issues!
My testing shows that most Japanese branded cars and SUV with electric steering works in Fail-Safe mode if the control unit (ECU) is disconnected from CAN BUS. The effort in Fail-Safe mode feels just right like my 2013 Honda Civic. Not too much and not too little. Just like Hydraulic Steering, if the Electric Assisted Steering completely fails, the steering is back to completely manual mode maintaining car control.
The biggest advantage of using EPS from Toyota, Nissan and Kia/Hyundai is that the EPS works in Fail-Safe. The ECU for the column is mounted remotely and cab be disconnected and removed. The EPS from Saturn Vue and Chevy Cobalt has the ECU that cannot be disconnected and must be de-soldered for remote mount. More importantly there is no Fail-Safe and a 3rd party eBay module is needed in order for it to work. Additionally , people have reported that with after market eBay module, the Saturn EPS does not self center the steering wheel coming out of a turn. You have to make constant corrections.
Below is the list of Car that I know of that has Fail-Safe Electric Steering. Only 3 wire connection. Ignition On, Power and Ground to the Steering ECU. That's it !
2004-2009 Toyota Prius
2009-2013 Toyota Corolla
2006-2011 Toyota Yaris - (With ABS)
2007-2009 Nissan Versa
2009-2012 Nissan Cube
2012-2014 Kia Soul
ECU Part Numbers:
2004-2009 Toyota Prius 89650-47102
2009-2013 Toyota Corolla 89650-02300
2006-2011 Toyota Yaris - (With ABS) 89650-52120 / 52050
2007-2009 Nissan Versa 28500-EM30A / 991-30303
2009-2012 Nissan Cube 28500-1FC0B / JL501-000932
2012-2014 Kia Soul B2563-99500 / 4PSG1312 / FPSG1312
The output shaft on Toyota is little larger than the rest and therefore the Borgeson 312500, 11/16 36 X 3/4 smooth bore weldable coupling should fits nicely. This couple fits the others as well. The Kia EPS is the biggest and appears to be most heavy duty. The Prius & Corolla EPS are very easy to find at salvage yards so this is the best bet. I picked up these EPS for testing for $35 each at my local pic-a-part

Tested one more EPS / ECU that works in fail-safe/limp home mode with fixed level of assist. 2008-2011 Scion XD
2008-2011 Scion XD It's almost identical to Prius. The Prius, Yaris and Scion Xd ECU share same exact plug and works with each other.
ECU Part Numbers that function in fail-safe / limp-home mode:
2004-2009 Toyota Prius 89650-47102
2009-2013 Toyota Corolla 89650-02300
2006-2011 Toyota Yaris - (With ABS) 89650-52120 / 52050
2006-2011 Toyota Yaris - (Non-ABS) 89650-52070 & 520140
2007-2009 Nissan Versa 28500-EM30A / 991-30303
2009-2012 Nissan Cube 28500-1FC0B / JL501-000932
2012-2014 Kia Soul B2563-99500 / 4PSG1312 / FPSG1312
2008-2011 Scion XD 89650-52A10
Waid, I purchased a Toyota Prius motor and computer box. When hooked up to a battery, the computer sometimes clicks once and the motor will operate only for about 2 seconds and then shuts off and I then have to detach and touch the ignition wire again to the positive pole of the battery to get the motor to operate. Sometimes when I connect the ignition wire, the box clicks twice and I get no motor movement. Bottom line is that I do not get more that a couple of seconds of use out of the motor before it quits working again. Note, I am using motorcycle battery and am wondering if that could be the problem. Any ideas from anyone.It has been a while since I posted on this forum. I am not making or selling anything.
