the tool, as all china clones, contains errors (zvn position for example) and poor quality components...i know that the tool work but is always better to rework it

Hello.

Sorry dear it's non sense, if it work ... it work.

Chinese poor quality is fake , these are false information propagated to sell same products made with sames components all from chinese factories but more expensive just for earn money.
The "quality" is only the firmware itself.

Why says ZNV are wrong position?
They are Mosfet transistors and i don't think your device will work if they are in wrong position.

If your device work well and want to prevent it to from harm you need to place protection diode at all voltage regulator , U3 - U5 - U8 and maybe U6 - U7 (cannot read information) .

i earn nothing! i want only to improve one low quality tool, its true that is work....but, if we made same things on fgtech v48-53 and the tool work without errors why i must not to do the same on this kt?
zvn and zvp are npn and pnp mos and they have D-S-G which to apply voltage, only for this particular for me is one big error!
the GENUINE fgtech v48 and v53 that i had have this component as i say...why i have to settle of your " if it work...it work"?
dont speak me about "earn", i'm not selling or producing tools, and if you work in the china market maybe you earn money also because the china market produce clone of all tools....then, i (we) try to arrange myself with this tools, my intention is to improve this tool, exactly as the others clone tools.

I try to read it with a cable usb DB9 with ftdi 232rq and won’t connect to chip will try to buy usb TTl cable and try after

by usb you cannot to read lpc, need uart connection to the board, by usb you can only read ft232 and eeprom with the same software that you use to fix eeprom and ft (mprog)

Sorry for missunderstood.
I'm not talking about you but about sellers who claim that chinese devices is of poor quality to sell you the same devices 10 times more expensive with supposedly better quality components (which ones?).
For example "KESS V2 5.030 2.55 THE TRUE EUROPE VERSION UPDATED PCB RED REWORK VR ACTIVE" for 1200€  ,they only provide a different firwmare (never try it).

zvn and zvp are npn and pnp mos and they have D-S-G which to apply voltage, only for this particular for me is one big error!

Why?

my intention is to improve this tool

Great   and it's different to redo a device that already works to make it ... work .
What improvement do you expect?
I bought many devices at Aliexpress for cheap (thanks chineses copy , i don't have enough money to spend it in original devices that i would use 10 times a year) and i am an electronics "engineer" , the only improvement i will is the one i gave you.
This is to prevent that in the event of a short circuit of the regulator (Out voltage upper than In because capacitor) , the input voltage (12V) goes directly to ICs which only support 5V or 3.3V then destroyed.

on bench box U4 is can receiver PCA82C250/1 or mcp2551
i don t know what is U2 and U1!
but, i thisnk U2 is 74HC14D
i don t have it to test

[cristim]

Can anyone help me to repair this bench box?

hi

if anyone need to rework pcb the component are the same of FG v53.

here is the list and pics of mine


KT 200


U13-U14 : L9613 / E-L9637D

U20 : HEF4011BT

U2 : LPC 2119FBD64

Q11 : ZVP2106 (look for the mounting position because the china copy are wrong)

Q12 : ZVN2106 (look for the mounting position because the china copy are wrong)

U18-U22 : ST 485B - MAX485

U19-U21 : LM393

U3-U5 : LM1117

U17 : PCA82C250 for 0-12v obd (PCA82C251 for 0-24V obd)

U10-U12-U16 : 74HC14D

U15-U23 : 74HCT125D

U24 : FT232RL

RELAIS LITTLE : OMRON G5V-1

what about relay
RELAIS LITTLE : OMRON G5V-1

5V or 12V ,You use 5V this same in V54 but in KT200 was 12V ? so what to use?

[carmageddon1970]

is 5v as in the old fg

Hi mate, 
How is working now? 
I just buyed and i try it on opel delco e98... 
Readed twice and different files. 
Try to write mod file and gave me boot error. 

this was a silly thing to do
why did you try to write a mod file if the read wasnt the same after each read?
you should never write anything until your 100% sure your read is correct

I have modified the KT200 according to the list and the CAN reading from OBD still does not work (only the K line works), the bench reads EDC17C46, and the Delco e 78 does not read - where could be the problem.
I read the same foxFlash drivers and everything works.

[dimitar]

I have the same problem......can bus works on bench only but not in obd or full system

and if the problem in in the obd cable/wire or in the black box?
