GM Tech2 clone program ECU with SPS in TIS2000

Here is the step-by-step instruction on programming GM (General Motors) ECUs with Tech2 scanner and SPS (Service Programming System) application in TIS2000.

NOTE:

Before using the SPS, make sure that the GM Tech 2 Scan Tool and the pc contain the latest software, the battery of the vehicle is fully charged, only the ignition is on power,
and all cables are connected properly. TIS2000 will not work on 2007 up GM, and software must work together with TIS2000 USB key. If you need to program Saab ECU,
you had to use Saab TIS2000 and USB dongle.

Main steps:

Step 1: Instruction for TIS2000 software

Step 2: Data request

Step 3: Data exchange

Step 4: Program ECU

Alternative Programming with “Pass Thru”

Check Programming result

Step 1: Instruction for TIS2000 software

1.Connect the Tech II to the pc.

Note: The hardware key (HWK) has to be registered prior to working with ‘Service Programming System’. To register a hardware key, the form that is enclosed with
the hardware key kit has to be filled in and sent to the address at the top. In case the form is missing, the document is also in the TIS 2000 newsletter (see icon in the
TIS 2000 tool bar). At first, the user receives a temporary code until the key is registered on the next TIS 2000 CD.

Hardware keys that have already been registered are still valid!

To register the hardware key select ‘Hardware Key Registration’ in the menu ‘Configuration’.

TIS2000 installation video guide

2.Start TIS 2000 on the pc.

3.Select the application ‘Service Programming System’ on the TIS 2000 start page.

9-1

4. On ‘Select Diagnostic Tool and Programming Process’ (picture below) screen make the desired selection for

1) the used Tech2 diagnostic tool

2) the reprogramming of an ECU that was not exchanged or the replacement/programming of a new ECU

3) the ECU location.

9-1

5.Click “Next” button to continue.

Step 2: Data Request

1) Connect Tech 2 scanner to vehicle. Power on device – “Tech 2” is displayed on the screen, then press “ENTER”.

2) Turn ignition to ON without start the engine!!!

3) Select “F1: Service Programming System (SPS)” in the main menu.

4) Press “F0: Request Info” on Tech 2.

5) If Tech 2 has already stored vehicle data they will be displayed now. In that case, Tech 2 asks you to either use the current data (hold data) or request further information from the ECU (continue).

6) For the selection of “Next” the vehicle has to be identified as requested by OBD II Scanner Tech 2.

Note: Depending on the model year and the selected model either a reprogramming of the ECU (F0: Engine) or of the TCM (F1: Transmission) can be selected.

7) During the Request Info the Tech 2 receives information from the selected device. If the ECU was replaced a “Request Info” has to be performed for the NEW unit. Since the new ECU is not programmed on delivery, the retrieved information is not complete. For that reason, TIS 2000 gives instructions as how to enter the missing vehicle data.

8) Follow the instructions on the Tech 2. Then press “Exit” on the Tech 2, switch it off and disconnect it from the vehicle.

Step 3: Data exchange

1.Connect Tech 2 to the pc, switch it on, and click on ‘Next’ on the pc.
2.Confirm VIN or, if necessary, enter correct VIN, then select ‘Next
3.Validate vehicle data and, if necessary, change with the pull-down menus
4. 9-2
5.Click on ‘Next’. Button
6. 9-2
7.A new window displays a “Summary” (follow below) with the selected data. Continue with ‘Next’. Select “Reprog” button to download the latest calibration data onto the TechII diagnostic tool.

Note: It is not possible to reprogram an ECU with the same software version.

1.The window ‘Transfer Data’ is displayed. A bar shows the progress of the download.
2.At the end of the download, a window is displayed with the request to connect the Tech 2 to the vehicle in order to finish the programming process.
3.After the closing of the SPS application the TIS 2000 start screen is again displayed. Finally, switch off the Tech 2 and disconnect it from the pc.

Step 4: Program ECU

1.Connect Tech 2 to the vehicle.
2.Switch on Tech 2 – start screen appears.
3.Turn ignition (Do not start motor!).
4.Press “Enter” in the Tech 2 start screen.
5.Select “F1: Service Programming System” in the main menu and then “F1: Program ECU”.
6.Follow the instructions on the Tech 2 screen.
7.During the download the Tech 2 screen shows the message “Programming in Progress”.
8.At the end of the download the Tech 2 shows the message “Programming was successful”. The button “Exit” leaves the program. First, turn off the ignition of the vehicle, then switch off the Tech 2 and disconnect it from the vehicle.
9.Turn off ignition for 30 seconds before starting the motor. Additional information is available in the section “Check programming”.

Alternative Programming with “Pass Thru”

In addition to the procedure described above, there is an alternative programming mode called “Pass Thru”. In that case, the data are directly downloaded from the pc to the ECU in the vehicle.

Although the Tech 2 is still needed in that mode, the data entry and the download control is done directly at the pc. Altogether, that method is faster, and it is recommended when a pc with TIS 2000 is within 3m of the vehicle.

1.Connect Tech 2 to the vehicle.
2.Connect Tech 2 to the PC switch on Tech 2.
3.Start TIS 2000 on the PC.
4.Select the icon ‘Service Programming System’ (Fig. 1) on the TIS 2000 start page.
5.Start TIS 2000 on the PC.
6.On the screen ‘Select Diagnostic Tool and Programming Process’ (See picture below) make a selection for

***Pass-Thru mode

***the reprogramming of an ECU that was not exchanged or the replacement/programming of a new ECU

***the ECU location.

Then clock ‘Next’ button.

How to solve 2009 Saab 9-3 1.9 TID non starter by GM TECH 2 ?

This post starts with the problem that 2009 Saab 9-3 1.9 tid no starter, then how to solve? Please go on reading following parts.

Car model and year:

2009 Saab 9-3 1.9 tid

General Car issue: non starter

Tool I used:

GM MDI Global TIS and GM Tech2

Trouble and what Global TIS and Car Scanner Tech2 find out:

They have read codes to do with ignition and immobilizer and found that the cim is not picking up the old or new keys in the switch he tells me that the chip in the key is not being energized so the cim can’t read the key.

Trouble analysis:

The chip in the key is read by the ignition switch, called the Ignition Switch Module (ISM). Maybe the fault lies there.

How to remove?

1.Operate/move the seats to their rearmost positions.

2.Remove the front side pieces from the floor console.

3.Remove the cover from over the gear lever housing, use 82 93 474 Removal tool in the rear edge of the cover and pull back.

4.AUT: Remove the clamp.

5.Remove the cover under the handbrake by pulling it straight out.

6.Remove the cover on the passenger side by squeezing the cover and lifting it up. Remove the compartment under the cover on the passenger side.

7.Lift up the rubber mat in the floor console storage compartment and remove the screws.

8.Remove the floor console screws; note that screws for plastic and aluminum are different.

9.Remove the sound insulation (certain cars).

10Press in the four catches (two on each long side) and press down the ignition switch module.

11.Lift up the floor console slightly and remove the ignition switch module.

12.Remove the connector; see “Connectors, handling and checking” item 1D.

13.Everything will be OK in the end. If it’s not OK, it’s not the end…

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.

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.

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:

http://forobd2tool.com/wp-content/uploads/2017/06/13/20-4.jpg

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?
