I'm reviving this thread once more as a result of finally solving the last piece of this 6MT conversion puzzle.
Even since completing the swap I have not been able to deactivate DSC. As many of you know, the SMG and 6MT use different buttons to deactivate the DSC, so, if you do this swap in a 2007 or older car you will need the SZM from a manual car which has the MDM button on it. These are very hard to find since there are so few 2007 6MT cars out there...well, I finally got fed up waiting for one to pop up on eBay so I bit the bullet and ordered one from my dealer:
Once you code your DSC for a manual car (2MA) you will have a fault for DSC button error or pushed for longer than 10 seconds, followed by a DSC shutdown in which case you can no longer disable DSC or turn on MDM traction mode.
Initially, I was expecting this and ok with it, not thinking anything of it as I knew the 6MT switch was different. The problem arose when I plugged in my new MDM switch panel and the error remained along with the mentioned fault code and still not being able to disable DSC.
After 3 days of pondering now, checking if software is different, or DSC unit is different it turns out that when coding the DSC for manual, it looks at another pin for the DSC_PASS signal which comes from the MDM switch.
How did I figure this out? In INPA, when viewing the DSC switch status, the DSC switch shows active full time when there is no signal incoming to the DSC pin.
I discovered this by accident swapping pin 4 with 41 as the schematic (incorrectly) calls out. When you do that, the brake light switch status comes on full time, so that led me to the fact that the phantom DSC_PASS signal pin was open since it's a digital signal which is either 12v on or off.
There are 17 empty cavities on the DSC connector...our lucky winning number when playing DSC pinning roulette is....................6, so, long story short:
SMG DSC has the DSC_PASS signal wire going to pin 41 from the DSC switch. When converting to manual, move the wire from cavity 41 to cavity 6.
Before you do this, make sure you move the other end of that wire out of the white little 4 pin DSC button connector (Blue wire) and move it to the little connector into spot 3 on the back of the SZM.
Your DSC TASTER status should be off as pictured when not pressing the button....not filled in like the 2 below it.
DSC passive can now be activated again once the DSC_PASS signal gets to pin 6 and all DSC OFF problems are solved.
Now I'm off to slap this thing back together.
