Looking for some Data to help complete conversion

Thought I'd post this here and on disco3.co.uk
I need some data from a working electronic steering column.
Hopefully one of you would like to run these test connections
for me and for the greater good of society.
I'm pretty sure that these tests haven't already been done before,
but if so, by all means please post them up here or send me a PM.

Please view the following diagram and measure the voltage at each of the red arrows
See more specific directions for some of the measurements.

All of these connection tests can be performed at the seat memory ECU which is under the driver seat (front portion)
You will need to detach it from the seat and lower it to perform these tests and get access to the
two needed connectors C2382 & C2384.

To gain more access to Seat Memory Ecu - Unplug the green seat switch re-route the wiring to
be able to lower the ecu and create more room - then plug green connector back in.
**Remember to unplug green connector and route wiring back the way it was before re-attaching
it back to the bottom of the driver's seat.**

Tests need to be performed with all plugs attached to ECU
Also it shouldn't make a difference with key On or Off (these voltage values were the same either way for mine)
However just to be safe and while you're in there try it yourself to see if these values change with
power On or Off (no start)

Here is a picture of the Seat Memory Ecu & Plug Positions
If needed C2382-9 refers to the plug connector C2382 - and the pin position 9 (wire) in this plug

Here are the tests from top to bottom in the diagram

A) C2384- 9 measure voltage (ground to chassis) when column switch is moved (tilt & tele)
C2384-10 measure voltage (ground to chassis) when column switch is moved (tilt & tele)

B) C2384-12 measure voltage here (ground to chassis)- should be 5volts

C) C2384-3 measure this output relative to ground
C2384-4 measure this output relative to ground

D) C2382-22 measure here and note voltage when column switch is moved in all directions

E) Also measure between C2382-22 and C2184-3, at the memory seat ECU while
moving the column switch as well (not in the diagram)

Some info:
I have an 2006 RRSsc (Basically a D3- LR3) that came with a manual steering column.
I am changing this over to an electric steering column.
All of the wiring is there for this conversion since the HSE versions had this feature.
The location of plugs with needed wires is in the lower kick panel by left foot -US or right foot -UK)
I've followed the diagram to the "T" and connected all of the wires to their proper locations.
Checked continuity for all wires from Seat Memory Module to actual Steering Column - All Good
Gap-Diag has also helped immensely (thank you Patrick and G-Team) with loading all of the needed
Steering Column configs for tilt/tele/memory, also Calibration for column etc...

The column is however still not functioning but with your help, hopefully it will be...
Have swapped out the column switch twice (with Used & New) - this isn't the cause.
Next will be the Seat Memory Module - but after I have some more data.
So if any of you are willing or need something to do....Much Oblige!

Thanks In Advance!

Yes! I'm crazy for wanting an electric steering column, just from research it has
shown to be problematic at times....But I needed a project...so here I am...

If you have any Questions/Clarifications about the above please send me a PM
Thanks Again and
You'll really be helping a lunatic achieve some sense of piece Of mind.
