Paddle shifters not working w/ fault code

Hi guys, long story short, I 99% completed manual to DCT swap myself and have a remaining problem.

Paddle shifter do not work and have 005A73 code.

Test i have done:

Continuity test from clockspring to dct transmission OK

voltage in pin 4(clockspring) or EGS_Up is at 7.16V

voltage in pin 6(clockspring) or EGS_down is 0V

When I erase the code, it come back at key ON instantely.

I have steering multifonction switch on Order but don't think its that.

Also I have a lithium battery , i've read paddle shifter un voltage sensitive?

Any help would be apreciated thanks.

I would like to know how the 5A73 is trigger. From what i know each paddle shifter will complete continuity to ground when activated. I don't get how the TCU know theres a problem when paddle shifter are not activated.

For those interested, i install new oem multifonction switch which include a 332 ohm resistance for downshift signal to be trigger and for upshift a 1k ohm. They are absolutely need for the tcu to see a standby voltage of arround 5.5v . If voltage is off, it will trig the malfunction. In the clockspring its pin 4 which is positive and pin 6 which is negative.
Paddle switch are now working . thanks
