(Review) How do I use GM TECH2 to replace Opel Corsa C ECU

This article is just sharing real experience when use GM Tech2. Hope this helps someone.

I decided to invest in some tools to diagnose my Opel. After a couple weeks of searching all over ebay, aliexpress and other online store, I finally found the cheapest one on OBD2TOOL, they were very fast to respond and answer all of my questions. I exchanged emails with Customer service for about 3 days before I finally decided to purchase a tech 2 clone here. I ordered it on Tuesday and I picked it up at Friday (I missed the fed ex guy and you have to sign for it). Yes, it only took 3 days delivery!

I paid $349 for it. The quality of this is amazing. I would never be able to tell it was a clone. I hooked it up to my car and was able to replaces Opel Corsa-C ECU.

So here it is….




Below is the procedure, I search and learn from forum members:

Obtain all ECU pin codes especially second hand ECUs (immobilizer or engine). Scan old ECU to obtain VIN code and then obtain car passes to match.
Obtain all keys they will be required at end of procedure. SPS program new engine ECU with vehicle engine code and VIN number.
3. Configure engine ECU CAN configuration (Engine/ programming/ program CAN configuration)
Configure engine ECU variant configuration (Engine/ programming/ program variant configuration)
4. Reset engine ECU if second hand ECU use pin code from car pass (body/ immobilizer / additional functions/ reset engine ECU)
Reset immobilizer (body/ immobilizer/ additional functions/ reset immobilizer)
Reset BCM (body/ BCM/ additional functions /reset BCM)
Reset instrument cluster (body/ instrument/ additional functions/ reset instrument)
5. Program immobilizer function (engine and immobilizer): this will program everything together includes new keys. Have all keys programmed (body/ immobilizer/ programming/ program immobilizer function).
Check and clear all fault codes Engine immobilizer dash BCM ABS and gearbox. Road test and recheck it.

Great! I can see Professional Diagnostic Tool GM Tech 2 replace a new engine ECU for Opel Corsa C successfully!

MB Star Diagnosis Coding Out ABC on Mercedes R230 Cars

MB STAR Diagnostic Tools software can code out ABC, here is the example on code out Mercedes SL65.
NOTE : the instruction here only for R230s (not any W215, W216, W220, W221)

To do this, you need a MB Star diagnostic SD Connect C4 with Developer mode. Hook up SD Connect diagnostic system to your car and when it reads your car, select Control Units, pick Information and Communication and you will see ICM :


After ICM, you will see Control Unit Adaptions :


From there, choose the year of your model :

From there, select Special Equipment


Select ABC :


Then go to the drop down tab and change it from PRESENT to NOT PRESENT, and click F3.
After that, turn off the car, with the doors closed.
Wait 1-2 mins and start the car back up (no more ABC codes and no white or red lights).

How to install SD Connect C4 WiFi on Windows 10

Have good success with MB SD Connect C4 windows 10.

I’m running Win10 on a Dell XPS15 9550 laptop with Intel AC 8260 internal wireless card installed.

After days of investigation and testing, the most important thing to understand is this. The drivers for your wireless card MUST support AdHoc functionality. The Benz diagnostic tools are the secret sauce that makes this possible. This can be verified at the DOS command prompt. The command is: netsh wlan show drivers
This command will show “Yes” or “No” on the line for “Hosted Network Support”.
If this line says “No”, AdHoc will not work properly.

Although I’m running Win10, Intel has drivers for the 8260 wireless card for Win8 which will enable proper AdHoc functionally.

The trick is to download the driver first, prior to removing your existing wireless driver. Download the driver ONLY, not any driver file with additional driver management apps included in the downloaded file.

Now you can go into Device Manager and remove your existing wireless card AND check the box that removes all software associated with it. My Win8 driver download file was a .exe file. I double clicked on it and the Win8 driver for my Intel 8260 card was installed. Went to Device Manager, right clicked on my 8260 wireless card and selected Properties. Clicked on Advanced and was able to see several AdHoc related entries. These AdHoc entries were not visible using the Win10 drivers.

AdHoc can now be verified at the DOS command prompt. The command is:
netsh wlan show drivers
This command will show “Yes” on the line for “Hosted Network Support”.
If this line says “No”, AdHoc will not work properly

With AdHoc functionality confirmed, additional DOS commands can now be used to enable Road24h wireless connectivity. The procedures for the additional steps required are well documented in OBD2TOOL or GOOGLE.

This is what worked for me. Depending on your computer skills, your results may vary.

If you find my posting to be of help to you, Thanks and Rep would be most appreciated.

Happy motoring !
