I’m here to tell you

It’s possible to coding NTG2.5 on the benchand test a few things, using SD connect C4 etc.

What you need to do is connect NTG2.5 with your Benz diagnostic tool SDConnect C4, you need to connect KL30/KL31/CAN-H/CAN-L, you don’t need to connect the ignition pin because NTG2.5 doesn’t have KL15.

And, you need to attach a 120ohm resistor as a terminal between CAN-H and CAN-L, it’s a request of CAN BUS protocol. You can check this. Found it on a forum

Then, if your connection are all correct, you should use vediamo to code your NTG2.5, the CBF file is HU25.cbf, you can’t use Xentry/DAS because there is no ZGW on your bench, so the Xentry/DAS will never be connected with NTG2.5.

If you want to test rear view camera, you just need connect your camera to the NTG2.5, but you need supply +12V power to your camera manually.

Manually trigger the rear view camera output via Vediamo:

Just press “Rev. Cam.” item like below image in the system setting page, the rear view camera will active if you power the camera up.

On a side note: KL31 bridge

KL 31 just means the Negative Battery Terminal / Ground (I am from germany and the schematics here and in other countries say that Klemme 31 (short KL. 31) is the Minus Terminal of an Mb Star C4.

So just connect Pin 15 (A-Block of the Quadlock Connector) to 12V+ (KL. 30) and Pin 12 to the Ground/Negative Terminal of your power supply (KL.31). And now press the ON Button and pray it works (which works always for me  )
