Hi all and thanks all for your responses. Here, i collect working solutions of Ktag or Kess V2 NO 12V. Hope it helps someone out.
Part 1: Cannot get 12v of output from Kess V2
I use a AC power to connect to my kess V2 adapter. The seller gave it. it it 12v and 1A.
When I use my kess I’m following the next steps.
1 ) Connect the adapter to kess unit
2 ) Connect the ac power adapter to the adapter
3 ) Connect the usb cable to kess unit and the computer and tun the software
My kess read ecus by OBD port. I read a seat leon 1.9 BXE perfectly. It is other edc16 ecu.
The Ksuite shows it has 12,16V-12,30V all time while it is trying to read.
I tested my power supply and it give 12 volts
Part 2: Ktag NO 12V
Got a Ktag Clone since a few months. did about 10 ecus with it, no problem! Since today i’ve got no 12 volt on red wires. Normally when i click read 12v appears on red and orange wires. Now only on orange. When i connect red and orange together everything works like normal.
