China clone -TCS CDP Pro and Multidiag Pro, what’s the difference?

They have three  biggest difference:

1 software: DS150E 2015R3 or 2014R3

2 pcb: one or two boards inside, and designed & produced by different factories

3 Bluetooth: with or without a BT module (and memory card)

In detail...

(New design) 2015.3 TCSCDP + with Bluetooth and 4G Memory Card

2015R3 TCSCDP Pro with Bluetooth A, best BT module (item SP122-B at obdexpress.co.uk)

PCB with a Bluetooth module

PCB with a Bluetooth A module

PCB without a Bluetooth module

Multidiag Pro china clone:

Multidiag pro with one PCB:
Multidiag pro 2015R3 DS150E Bluetooth,
Multidiag pro 2015R3 DS150 without Bluetooth, basic configuration

Multidiag pro 2015R3 DS150E Bluetooth with a 4G memory card

(Full kit) Multidiag pro 2015R3 DS150E Bluetooth with a 4G memory card, with all cables  

Multidiag pro with two PCBs:

Multidiag pro+ without Bluetooth, 2015R3 DS150E, cheapest, 

Mutidiag pro Bluetooth 2015R3 DS150E, with a 4G memory card

unit with one PCB

unit with two PCBs

The last, 

1 PCB unit or 2 PCB unit, Which one should buy?

- 1 pcb unit works good

2- 2 pcb hardware works like a charm, but must have luck... 

3- the white tcs is a good tool

2015r3 TCS CDP pro PCB v8 v6 v5 v3

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

  

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:

2014.R3 TCS CDP without Bluetooth

2015R3 TCSCDP Pro+ with Bluetooth

2015R3 TCS CDP+ PRO without Bluetooth

(New Design) 2015.3 TCSCDP Pro+ OBD2 scanner without Bluetooth

(New design) 2015.R3 TCSCDP Pro with Bluetooth and 4G Memory Card

How to do TCS-CDP pro clone can’t read BMW ECU

Customer meet this TCS-CDP pro problem:

Software supplied with its softwware 2014 release 2. The software installed and activated OK. i tested the unit and it passed the test OK; but unluckily, it does not communicate with any car... only use USB cable ( not bothered with Bluetooth). After vehicle selection, the system cannot read ECUs and generates silly error messages "Vehicle not responding (Fahrzeug antwortet nicht)".

Error message:
Startup
Initiation of the tester... YES
Searching for the interface... YES
Establish communication... NO
(ISO 157656-4, SAW J1939-21)
Vehicle not responding
The vehicle is not responding to the diagnosis inquiry made. Please make sure that the tester is correctly connected to the vehicle and that the ignition is turned on, and try again to establish communication. If communication fails again, it is possible that the diagnosis function is not supported.
Software:
2014 release 2.
The software installed and activated OK...and tested the unit and it passed the test OK
Hardware: (new VCI), Serial No.100251, eOBD 114, Firmware version 1423.

* First modification- FAILED!
I tested on Mercs and BMW. I opened the CDP unit and observed that two boards are not connected correctly. So, I pushed them together. This has improved a bit, as the unit now makes a clicking noise when connected to a car. Even can read the VIN, but on BMW failed to read the ECU. I will try later on a different car. But this is already a bad news (no BMWs).

Then, I contacted the supplier and was informed that this TCS-CDP DOES NOT WORK with BMWs and Mercedes cars !!!!!

* Second modification- FAILED!
Then i was told that "the device actually does not work on any vehicle that uses SAE J1850 (PWM and VPW) because it has a fake OKI m6636 or it does not have it at all... The OKI chip is only for cars that support the PWM/VPWM protocol like Ford. BMW didn't use the PWM/VPWM protocol." And this user did fix the problem and used the same interface for all BMW cars..TCS CDP interface, removed from old devices like tv´s, radio´s etc. check all solder Joints of all components (especially relays)..

But I didn’t try that, and decided to purchase another TCS CDP from a different supplier. White this time... When it arrived I tested it immediately on the same BMW 7 E66… and guess what …. Same problems remained.
New TCS CDP white:

***** Third modification- Successfully SOLVED finally!
the problem with the m6636 is in the cdp pro, not in cdp+. replace the 2 diodes (D701 and D703) with 1n4148. back the pcb.
Then gained the communication with BMW car which I could not communicate with before.
So, well DONE!

Hope it helps.
