Question PDC of '04 after SMG to 6MT swap

I successfully swapped my car and did the 6MT coding using ECUworx Tool.
I didn't get the Clutch switch nor the GPS.
So my PDC is not working,
I wired a cable from the back of the cluster (pin7).

Can i code the car to think that it is always in gear (even in neutral) so the PDC works without GPS or extra wiring ?

Kaiv did my swap and PDC works flawlessly. Might be worth PM him to see how he coded it.

Where you located? If you're in Norcal I can help.

I recently did this for a friend when I did all the coding and DME modifications to convert his smg car to 6mt. He has no GPS or Clutch Switch, so I coded this out. He ran the wire to the back of the cluster and I can't recall if it started working, or not until after I updated the VO in Ncsexpert and reflashed the appropriate modules...

Do you offer swap services?

DME code and clutch/gear switch has nothing to do with PDC working. And really, neither does NCS (possibly the instrument cluster needs recoding for it to send the reverse signal). PDC will also continue to work properly on pre-03.5 cars without wiring, which is probably what the situation was in your friend's case

So what's the solution for my case?

Bypassing GPS?

My apologies as I was unclear in my reply trying to multi-task at work. Lmao.

Friend's car is an 03.5 and I believe you are correct Terra as I was under the same assumption that the AKMB does indeed control the signal to the PDC after the swap? Maybe this is due in part from adding the wire and the PDC not looking for some sort of SMG function check?

PDC did not work on his car until after I updated the VO to remove the SMG option code and reflashed the appropriate modules. I think once the AKMB was updated to a manual car config, the PDC no longer required this and started working. Honestly didn't take the time to dig into it deeper once it started working but that would be my guess lol.

I have a friend who's local that I believe (Matt) nervous24 referred you to for the mechanical end (I just don't have the free time to do this part or I'd be willing), and I can take care of the coding. I did his dme file remotely and had him flash it to the car so it could drive after they did the mechanical work, then Matt drove to me and I did the rest of the coding to make the car factory manual trans config.

If you can coordinate with him for the trans work, I can do the coding. Pm me.

Adding the wire is probably what did the trick. What the PDC looks for is a reverse signal. On 03.5 cars, it takes the reverse signal from the K-bus instead of a direct connection. On manuals, the instrument cluster broadcasts the reverse signal. On SMGs, the transmission module broadcasts that signal. That's why the wire has to be added on SMG swaps.

Even on pre-03.5 cars, the wire is needed for other functions (like mirror tilt)
