same problem as recording images to the memory card via the Tech 2 and TIS

Hello everyone. A few days ago saw that often face the same problem as recording images to the memory card via the Tech2 Scan Tool and TIS.

Initially I thought this is a typical problem with MAX232, only a little deeper, I saw that the Tech 2 is well connected with TIS, but attempts to write through it, memory cards, success did not. Having started to study the problem, I found the following that through the card reader in your laptop works, and through TIS not. And that’s what this difference is expressed: the fact that the card reader work with cards with 3.3 Volts and 5.0 Volts. And that is what is written in the instructions to the Tech 2, the photo shows.
In the end, I checked everything with me in the presence of a memory card, here is their photo:

As a conclusion, until I found how to solve this problem, it is best card to rewrite only through the card reader in the laptop. Another way to try to lower the voltage in the Obd2 scan tool Tech 2 so that it more accurately worked with credit cards, there is a successful experiment, but there are very few tests that were carried out and what it may cause, or to try to slightly modify these memory cards.
Just want to try another experiment, but I still havent for it is only necessary, as only something I can do, or find a better solution will be described later.
Card No1


Card No2


Card No3


I can’t promise anything, but maybe will write the other day a couple of videos like this Car Scanner Tech 2 works.

GM Tech2 pass-through or go-between Method to Program A Module

If you’re trying to program a module, there are two methods. One is pass-through and the other is using the tech2 diagnostic scanner as a go-between.
In detail… look here:
The pass-through is to use with a laptop in the vehicle and it just uses the Tech 2 as the connection between. This is the fastest and easiest way to do it.
That is, the data are directly downloaded from the PC to the ECU in the vehicle.
Although the GM Tech2 is still necessary in the mode, the data entry and the download control is done directly at the pc. Altogether, the method is faster, and it is recommended when a pc with TIS2000 software is within 3m of a 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 TIS2000 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.

The go-between method is for when you can’t bring the computer into the vehicle and uses the gm Tech2 scanner as a go-between. You connect the Tech 2 to the vehicle and download the module information that you want to program. Then you disconnect, run to the computer running Tis2000, connect it to the computer and download the programming information for that module, disconnect again and run back to the vehicle, connect it and it automatically programs the module. It can take a long time depending on the module (PCM is the longest).
Have fun in professional diagnostic tool GM Tech II programming!
Good luck!
