Page 17-21, I try to perform that procedure (torque sensor learning) but once again I can't perform that procedure without clearing the codes from the EPS memory. I paper clip 4 to 9 and all that happens is the EPS light blinks code 14, need to clear that before it will let me perform the torque sensor learning on page 17-21.
Follow the directions starting on page 17-21 below the words "Service Check Signal Circuit Method". It is a continuation of the previous page "Clearing EPS DTC's"
It notes: Use this procedure when the PGM-Tester software does not match the year/model vehicle you are working on.
Instead of using the PGM-Tester for step 3. use a jumper wire or paperclip.
anywhere in the helms manual where it say's to use PGM Tester SCS method it say's to connect the PGM-Tester and use it to jump the SCS to ground, well when you do the jumper "blinky" trick you are jumping PIN9 (the SCS wire brown) to a ground PIN4. It is the same thing as connecting the PGM-Tester and having it ground the SCS for you.
EDIT: The Torque Sensor learning isn't until page 17-45.

I think I might know what the problem is, when I put my old torque sensor into the new rack I didn't center the stamped "AB" letters on the sensor shaft within 30degrees of the rack guide bolt. I will take the sensor out today and do so.
Thanks for your help sendergreen, with the paper clip in it just blinks the code 14 and 21 and won't let me perform either page 17-21 or 17-45 in helms manual which are strikingly similar. Hopefully installing the torque sensor centered will fix the problem.

First off - what connector is this talking about? The OBD-II (which appears to be the same as the "DLC" connector) does not have pins 9 and 14. It has 1, 6, 8, 12, 13, and 15 and the SCS signal is pin 1. I tried shorting it to ground both after the ignition was already on and before turning it on (i.e. turning the ignition on while the line is shorted) and it did nothing.
I'm an engineer who designs electronics for a living - so I know my way around wiring, multimeters, and whatnot - but I'm stumped!
Thanks
EDIT - ooh - I think I might have figured it out.... there is a link in THIS thread that has pics and apparently they number the pins differently than what is shown in my Helms p17-44
