Find a solution to fix Kess v2 clone bootloader adapter problems. Just put it here for sharing.
Kess v2 with ksuite 4.036 (China clone)
I am having problems with my bootloader adapter for Kess v2. Kess is reworked to 4.036 and works with OBD cable. I tried to use bootloader adapter and cable, but failed to read any ecu. I tried to connect EDC17CP14 (on the bench and without boot pin- obd mode on the bench), no luck with Kess (but my reworked Galletto worked with similar wiring ID + read OK).
I already checked the wiring in the cable connector- fixed some wires, but still nothing.
I think there may be something wrong in the bootloader unit.
4 steps to solve bootloader adapter problems:
Step 1- fixed the wiring
i fixed the wiring in the connector that goes into the bootloader module like in the picture (Ktag has the same) 4 wires were wrong in my connector.
Step 2- resoldered the mosfet
And I resoldered the mosfet (in the middle of the module- near the middle LED).
Step 3- read ECU without opening
I then got the power to the ecu. But it didnt read it, probably because I didn’t connect the boot pin (that needs to be soldered on the ecu pcb). I tried to read it without opening, because I borrowed the ecu.
So I finally got the time to test my bootloader module with all wiring (boot cable attached). Once I opened the ECU (edc17cp14) and connected the boot pin, I was able to succesfully Id and read the ECU.
Worked like a charm!
The main problem was the soldering of the mosfet transistor in the middle of bootloader pcb, and I remowed the extra wire that was on the other side of the pcb.
Hope this helps those with Kess V2 unit from China
