Comparison of TCS CDP PCB v3.0 v5.0 v6.0 v8.0

TCS CDP pro+ PCB has been updated and improved for several times. So, what’s the difference of TCS CDP PCB v3.0 v5.0 v6.0 v8.0 and how much do you know? Read the thread.


Now, it’s v8 pcb of TCS CDP +
v5 not work on nissan qashqai 2012 1.6 dci
v8 work well : v8 it’s better

sp122-c-tcs-cdp-pcb-bluetooth (2) sp122-c-tcs-cdp-pcb-bluetooth (1) sp122-c-tcs-cdp-pcb-bluetooth (3)



There are two kinds of v8 pcb:

V8 PCB with a high-quality Bluetooth module:





V8 PCB with a normal Bluetooth module:




it’s v6 PCB but same like v5



TCS CDP v5.0 PCB with zener diodes 30v



V5.0 PCB original vs. copy:
original v5.0 (2x fake 9241A=lm393 installed, KL only, not KKL) needs 5v zeners installed, if removed KL line stop working.
Original v5.0


V5.0 copy



New 5.0 pcb vs. Old 5.0 pcb

removing or replacing d701 and d703 diodes in this new 5.0 pcb version

new 5.0 is supposed to work ok without modifying the zener diodes
because pcb is completely different to previous versions and diodes are supposed to work as they should

Previous v5



New v5



It was v5 became v3



Amazing !
How these two will fit “pin to pin” it’s a mystery for me. Unless your PCB board is a completely redesigned version.



Pcb V5.0 vs. Pcb V3.0

with v3.0, 5v zeners must be just removed, or replaced with 30v zeners for trucks support
if modded v5.0 by robertdz is exactly = v3.0, again 5v zeners must be removed or replaced with 30v zeners.


different tracks and design



in case v5.0 pcb was designed for lm393, pins 6 and 7 would shorted on both left and right ic’s


Edit: tracks of 9241 on the right are all dead, no sense to replace it with another lm393, just the one on the left


NOTE: TCS CDP+ buying guide:

FGTech V54 read & write LUCAS 1708 to 2005

Clone FGTech V53 and V54 FGTech reads and writes LUCAS 1708 to 2005 by the OBD2 cable + mini adapter + adapter VOLVO 8pin (FH12).
FGTech V54 adapter pinouts

8-pin adapter pinouts:
4 & 5 —- GND
16 ——– Vbatt
2 & 13 — CAN hi
10 & 12 — CAN low
4 & 5 —- GND
16 ——– Vbatt
9 ———- CAN hi
8 ———- CAN low
Up 2006 years (FH”13″) EMS2 by BDM only, because read only part of the data.
EUR 5 it’s EMS2.2 with MCP5554 … It does not support large memory MCP5554 by J-tag.
Good Luck!

How To Solve Ktag Ksuite 2.28/2.31: No internet connection

I used K-suite 1.93 or 2.10 and works well, but now I have dump from car that this versions not recognize it and I want to use newer software for my KTAG programmer.
Tried install Ksuite 2.28 and 3.21 but on startup give me same error about: “Connection to the internet not detected: check that you have a working internet connection then try again.

When I click “OK” Then main menu shows, but almost all are grey. Older versions still work without problem.



How do people think of Ksuite 2.28 or 2.31 start problem? Here you go…


from v2.26 ktag working only with internet connection


2.25 Last working soft since now


there is no point using this software with your clone
install it, then overwrite it with the 2.11


If CKS not work, Install newer KSuite except the C++ Runtime, and without deinstall, install 2.08.
Then it works.


Did you try with Kess v2 on Bench? Connecting with universal cable? Without Boot Mode?

Kess v2 china clone has been verified to work no issues with Ksuite v2.28.
If all not work, then get an MPPS and try. MPPS is always a good backup tool specially for VAG. Some ECUs do so weird things, nobody can explain, this is why most tuners have more than one tool from different companies.



So, choose a lower version ksuite for Ktag clone or a tested ksuite 2.28 working perfect with kess v2….
