The GM Tech 2 is the factory tool for all makes and models of GM vehicles from 1992-2008. Prior to 1992, the Tech1A or Mastertech is the preferred factory tool. With GM authentic software, the Tech 2 provides the same level of functionality that is available to dealers. This tool allows you to scan, retrieve codes, graph data and have full bi-directional control when diagnosing powertrain, chassis, body and network issues.
The large backlit screen is capable of showing nine sensors at once as well as test and graphing. The snapshot graphing feature allows you to catch any glitches or failures. This tool allows you to store DTC, freeze frame and failure data and view the status of tests as they are running. You can also connect other devices to the Tech 2 such as SPS reprogramming through the RS232 communications port.
