Kess 5.028 from 16pin.
I reworked the SD card on a genuine Sandisk Ultra.

Here are high resolution pictures from 16pin KESS 5.028

For now I only changed the SD card.

PCB is good.

I have already changed SD card with a Sandisk.
I will change some transistors PD with A6C.
I will change all China capacitors with Panasonic capacitors.
I think buzzer is useless but I have a spare buzzer muRata here.

I advise to rework it like all China Kess.
For now it work well with all protocols tested, like Kess v2 5.017.
I have not tested Virtual Read.

Some people have suddenly had their SD card corrupted, so I would recommend to make a backup of the original SD card before using the Kess.

You can make a backup with the software “ImageUSB”

If at insertion the computer ask to format the SD card, don’t format it !!!

 

Note that, 16pin just updates Chinese Kess v3.099 to v5.028 but they are not reworked.

 

 

I continue to make my interface more reliable with Ksuite 2.47 that I modded to start with Kess v2 5.028 (or Kess v2 5.017).
Works perfectly and without USB dongle.

The benefits are many checksums and bugs corrected.

5.028 + Ksuite 2.34 don’t support unlock PCR 2.1 through OBD
But 5.028 + Ksuite 2.47 maybe support unlock PCR 2.1 through OBD

(I have not personally tested unlock PCR 2.1 through OBD).

 

4.036 good china clone is confirmed to be able to to unlock PCR 2.1
5.017 + Ksuite 2.47 should have good luck with PCR 2.1 unlock
