So far, i have used it for a few data. The cheap one still works great. I don’t know how the genuine works but i am satisfied with the clone one.

My friend who has ever used a GM Tech2, says the clone’s screen is much brighter and buttons feel kind of different- buttons on the original have a distinct “click” feel to them while the clones are mushy

The only thing I’m disappointed by that I didn’t get the case. The other forum member stated that the price would be much more if you got the case. I wish I had done some more research because I found several sellers selling the same thing with the case for around the same price. However, I did feel more comfortable buying that from the same source as the other member.

It will work on any GM OBD2, meaning 1996+; now it’s updated to 2013.

I have used the tech 2 scanner to reset IMMO for my OPEL Corsa-C 2005
Plug GM Tech2 cable into OPEL Corsa-C socket;
Boot up GM Tech2 diagnostic tool;

Enter into Main Menu;
Click Diagnostics to select car model and year;
Click Body >> Immobilizer >> Partnumber >> Additional Functions >> Reset Immobilizer, next you need to enter security code.

Step3:
Operate according to the tips, until it appears message reading “Reset Immobilize. Reset completed successfully!” It is Okay.

SAAB can’t start after Heat Engine Flameout

http://forobd2tool.com/wp-content/uploads/2017/08/1/14-1.jpg

Fault: A SAAB car has run about 50 thousand km. After the heat engine flameout the car couldn’t start again.

Check: After testing, the starting motor can work as usual. The engine seemed start the car when it just rolled. After diagnosed with GM Tech2, there was no fault code in Engine control unit. Checking the spark plug, electrodes filled with petrol. The spark plug “drowned”. Although dried out the petrol and tried to start the engine, the fault still appeared. According to these situations, it can be certain that car ECU had no problem. Then checked the engine from many aspects including gas circuit, oil passages,igniting circuit,cylinder pressure,gas distribution and ignition timing. Referring to the previous checking results, gas circuit, oil passages and ignition were all ok except ignition timing cylinder pressure. Many components should be taken out when proofread timing, so checked the cylinder pressure first. After connected to cylinder compression gauge, started the engine. At the first time, the reading was about 1MPa. When the engine hadn’t stopped running, the maximum reading reached 1.2 Mpa after the second compression stroke. At that time, the car deviations seemed larger than ordinary cars. Let the starting motor crank up the engine for a longer time. The maximum reading of cylinder compression gauge can reach 1.6 Mpa. But according to the standard, the OBD2 Scanner pressure of this car should be between 0.9 MPa to 1.2 MPa. Based on my repairing experience, it seemed that the silencer would be plugged by something. Run the engine again, I checked the exhausting situation. Oh, there was no air-out. Took out the 2 lambda sensor at the front and run the engine, the engine rolled and started the car successfully. Everything was ok. Took out the silencer and checked it, I found that the back of it was so heavy. I used endoscope and found that it was plugged by ices.

The owner just drives the car during the quotidian commute. The Professional Diagnostic Tool runs about 20km everyday and it hasn’t run at a high speed for a long time. That caused the back of the silencer can’t discharge the water, it’s colder in these days, the water became ices and the silencer was plugged.
Troubleshoot: Clean out the water and ices in the silencer, meanwhile let the car run at a high speed at irregular intervals.

(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!

China GM TECH 2 does everything a real Tech 2 does, how?

10-06-2014 Update:
I just placed my order GM TECH2 which is the complete package with the 32 MB card from obd2tool.com…

10-10-2014 Update:
It still hasn’t shipped according to their website. I contacted them asking why it hasn’t shipped yet. They are quick to respond, GM TECH2 from obd2tool.com is out of stock now and hope I would be patient to wait another 3 days, they will try their best to arrange. She even informed me that she declared a $69.00 value to help keep my customs fees low. Since uobdii.com own good reputation, then I choose wait.

10-13-2014 Update:
I received a notice from the vendor that my GM TECH2  Scan tool  item  has  finally  shipped….. today!!!  I  got  a  DHL track number.

10-20-2014 Update:
I received my Tech 2 today. It was a longer than expected shipping time but am quite happy with it so far. I have not yet used it and my first task will be to perform a CKP relearn. I’ll let you know how it goes in the following parts.

Here are some pics:

Package: I did receive the TIS2000 software disc. It was in the bag along with the product stickers. So yeah, I got the full package.

What GM Tech 2 does?
I just performed a CKP sensor relearn and it went perfectly. No problems reported. I also performed a complete diagnostic of my ABS including the motor and EBCM. No problems reported. I also went for a drive for some real time data logging. All looked good. It was amazing to note all of the misfires that were being reported prior to the CKP relearn process. No misfires after the procedure.

Well gentlemen, this unit appears to do everything a real GM Tech2 does. It works perfectly so far. The general quality of the unit also appears to be quite good with a robust case and very bright and clear screen. I am very satisfied so far. I know that I haven’t even begun to scratch the surface of what it can do and I guess I will discover its various functions as time goes on. If anyone has any questions, please let me know.

What Windows Operation Tech2 is compatible?
I keep an old Windows XP laptop in the garage which has my service manuals for all my cars including the Mercedes BENZ C5. At first I’m not sure what I can do with the TIS2000 software, then after I check find it’s working. Someone said VMWare works, and someone suggest Windows compatibility mode works sometimes. Try setting it for windows 7 compatibility and see if it works then, or try another mode like XP. I haven’t try this, and your options?
