O3 retrofit of Trailer - Error in VCDS

[MasterPrenium]

Hi guys,

 

I've retrofitted a Trailer bar to my Octavia mk3 (100% OEM parts). Everything went well except the electronic part. I've fitted the Skoda Original wiring Harness for O3. I've set-up all my fuses.

I think I've correctly coded all other control unit (engine, park assist ect...).

 

I got one remaining error in Trailer. And got a big error while switching ignition ON. I've tried lot of different coding for Trailer, but the error remains...

If anyone has any idea on how to fix it.

 

EDIT :

I checked the values for terminal 30 inside the control unit, I just found one strange thing (Voltage from engine) :

 

Should there be a wire coming from the engine ? I can't find any on Erwin schema.

 

Note : I doubled-check my fuses and they are all OK, fitted in correct original place (100% like OEM wiring).

 

PS : complete scan attached

Even after fixing this error, by adding another +12V (Terminal 30) to pin 1 on the six pin connector, I'm still having a big warning message with strident tone on my Instrument cluster saying to check the Trailer... I don't know what I can do anymore, no other errors apart the Reverse Camera calibration...

 

If anyone is having any idea....

Looking at the superb manual, it's written that this message came when the trailer isn't fully opened or fully closed (swivel model, like golf mk7 ect ...), this can explain also why I was needing the additional wire.

So I think I should change some parameter to tell the control unit is for manual trailer operation (no swivel), found nothing in coding neither in adaptation.
I need to tell the control unit it's a PR code 1D2 instead of 1D4.
Maybe it's some parameter to upload, can be done with VCP ?

If someone is having any idea...
