Even for the best vehicle diagnostic tools, errors are always hard to avoid. So people present some problems to us after they buy the GM Tech2. And today I wanna pick 3 main troubles here and give the answers to other people who have bought the tool.
The first question is that after you bought it, you may meet the condition that the TIS2000 software can’t be installed and no identification.
Don’t worry, if the TIS2000 you are trying to install has contained in the GM Tech2 software, then install the TIS2000 software is useless. To program electronic control unit, you would better buy an extra TIS2000 to work with the GM Tech2.
The second question is that find some errors after receiving the GM Tech2.
When you meet this trouble,the first thing you should check is that if it is blue screen. If it is, then just replace the Blue Screen Chip is ok. If it is not the problem of Blue screen, please send the seller the self-test report to check where the problem is. If you don’t know how to operate self test, you can consult the self-test manual at GM TECH2 “technical support / service”.
Once the tool starts to smoke, and even your car voltage become 14V from 12V when you use the GM Tech2 for the second times, please follow the right operation steps as what I say. Before you start diagnosing, please turn on the ignition and then connect the GM Tech2 with your vehicle, you would better test the voltage when the car starts , because during this process, a part of vehicle’s voltage will reach up to 24V or higher, especially for the vehicle which has a poor contact of electrical ground.
