GM Tech 2 software card

Hello to everyone. Today I want to talk about Tech 2 memory card. I don’t fully understand how to test. In fact, not often but sometimes get a bad card, visually for him not to say anything, even putting them in the Tech 2 they will be loaded. But on some menu Tech 2 Scanner will just restart. I have it booted from the menu on the device, specifically in the Hardware version. With 99% probability he would hang in the engine block Engine Data 1…3. Not always, but sometimes he wrote ADDRESS ERROR – PROCESSOR HALT. Later I bought another card, it didn’t hang, then I copied the software to both had the same version, eventually worked correctly only 1 card, or other periodically rebooted the device or just all hung, helped turn off – turn off the car diagnostic scanner Tech 2.

Here is a photo of my bad card may still try to solder, who knows things worse for it clearly will not. Yes, and to override the card is best to use any laptop or desktop computer with PCMCIA, as the Tech2 Scanner this is often time consuming, and pieces not entirely successful cases.
