Can Tech2 work to diagnose a 2005 GMC – Sierra 1500 truck?

Want to use our Tech2 to diagnose a truck? You need to buy an additional truck adapter because our Tech2 is compatible with trucks but only packed with the car adapter.

I bought one TECH II, and the TIS2000 software can’t be installed and has no identification. What’s the problem?

If the TIS2000 you are trying to install is contained in the TECH2 software, it is useless to install TIS2000 software. To program an electronic control unit, I advise you to buy an extra TIS2000 to work with Tech2.

After receiving TECH2, I got some errors.

If it is a blue screen, replace the Blue Screen Chip. If it is not the problem of the Blue Screen, please send us the self-test report to check where the problem is. Have no idea how to operate the self-test? Refer to the self-test manual at TECH2 “technical support / service”.

For GM TECH2, one button doesn’t work; how to fix it?

If you have a new version of Tech2, there are two ways to solve it: 1) we send you a new button to replace; 2) please send it back for repair. If you have an old version of Tech2 installed with the newest software, the button may not work.

When I use TECH2 for the second time, the tool starts to smoke, and my car voltage becomes 14V from 12V, what’s the matter?

Please follow the correct operation steps: before diagnosing, turn on the ignition and then connect the TECH2 with the car. When the car starts, you’d better test the voltage because, during this process, a part of the car’s voltage will reach up to 24V or more, especially the car which has poor contact with the electrical ground.
