How to update Kess v3.099 to Kess v5.028

Kess v2 version 3.099 to 5.028 update tutorial - This topic is for information and educational purpose only.

(Big thanks to kitnoos2002 )



Pics from Russian KESS 5.028.

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.



Kess 5.028 PCB naked VS reworked : 

Examples of genuine parts VS Kess clone parts : 

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

Kess V2 unlocking Simos PCR 2.1 - connection, wiring, tips&guides

Possible to OBD unlock Simos PCR 2.1 with Kess V2 clone?

Look here: all information can be found here to help you unlock PCR 2.1 using Kess v2 china clone.

Connection:

ECU connection for the bootmode unlocking procedure only!

1. Connect the ECU to the bootloader adapter
2. Power up the bootloader adapter with a stabilized 12v power supply
3. Connect the cable 14P600KT02 to the 14P600BTLR adapter
4. Follow the instructions provided below

Wiring diagram:

1. Solder a wire to the CNF1 pin
2. Solder the 470 Ohm resistor on the two pads
3. Solder the 1K resister on the pad

 

Test:

Basic info:

Tested and confirmed working by me on 4 ecus /cars

only on Chinese clone not reworked unit: ktag 6.070, kess v2 v4.036, ksuite up to 2.15

Tips and guides of tools for use:

pcr 2.1 need to be as you know unlocked before writing .

On this ecu pcr 2.1, ksuite (kess v2 or ktag) seem to be more stable than fgtech on pcr but work too sometimes: i get error with fgtech on one pcr2.1 but no problem with ksuite . 

So if you have both tools , prefer ksuite seem to be more stable & flawlessly and car run ok .

After you get you ecu unlocked in boot mode , with fgtech just remove boot and left pin connection , and read or write on bench .

On ksuite tools , you can’t read or write with ktag , only unlock . (alientech need to work on it…)
with kess it’s ok , BUT , you can’t use the tricore module !

The problem is that the harness is plugged in the tricore module . so you have to build your own bench cable : just get a obd female plug on a scrapyard , and wire +12 gnd and can h/l (kline is not used but you can wire it it will make a universal bench cable) .

The trick to get communication error free on both fgtech and kess cable is to use a strong external psu .

when the tool id or read or write the ecu , the ecu will perform a kind of reset , and the big cap inside the ecu will go charging , causing a drop in voltage if your psu isn’t strong enough to handle it . THAT WILL CAUSE THE COMM ERROR . That’s the only thing you have to take care . 

when i made test with many little psu (like one you get with your tools) i have seen 7 volts drop some time , so the ecu is shutting down and no comm . 

you can use computer atx psu modded to work on bench (green wire plugged on ground to power on ) i think anything that can provide +12v 2A will be ok . i didn’t need more than 12v just a stable 12V . 14v unstable will not be ok 

that’s why on the car you have no problem , car battery can handle the cap charging current .

There is no immo caused comm error on this ecu , psu is the problem !!

So in conclusion : good psu and obd home made bench cable , remove tricore module on kess = 100% tested bench flashing solution for pcr2.1 .
