Replace by quality components.
Thx button would be nice.
Free for everybody!!! No more payment for this!
TRY ON YOUR OWN RISK
Part 1 – KTAG hardware rework
Ktag before rework:
KTAG hardware rework solution:
k6b = BC817-25 SOT-23 (in some originals)
All capacitors should be replaced with the exact same one but new
Part 2 – Kess v2 hardware rework
Kess v2 pcb before rework:
KESS V2 rework solution:
Transistors to use :
NFE61PT472C1H9L (connect ground for all of them)
1uF – 35V
220uF – 10V
10uF – 16V tantalum
Fill up all holes from side to side
Use photo as reference if others components are different
With KESS V2 you programming directly through the OBD port of the vehicle, while with Ktag (Ktag 2.13) you need to take apart the ECU and open it, after you can make the read/write operation.
Many ECU has the advantage that can be read and write from OBD port (so KESS V2 is perfect), but there are lot ECU that need to disassemble from the car and open and this is the case for all the ECU that need to be programmed with Jtag, BDM and Boot protocols, so KTAG is needed.
