GM Global Diagnostic System (GDS) 2022 is an advanced diagnostic tool used by General Motors (GM) dealerships and authorized service centers to diagnose and troubleshoot issues with GM vehicles. It is a software-based system designed to interface with the various electronic control modules (ECMs) and sensors in GM vehicles, providing technicians with access to a wide range of diagnostic and repair information.
With GM GDS, technicians can perform tasks such as:
- Reading and clearing diagnostic trouble codes (DTCs) from vehicle modules.
- Monitoring live data from different vehicle sensors in real-time.
- Performing system tests and calibrations.
- Programming and updating vehicle modules.
- Accessing technical service bulletins (TSBs) and service information.
- Conducting special functions and adaptations for specific vehicle systems.
GM GDS 2022 is crucial for accurately identifying problems in GM vehicles and ensuring proper repairs. It is typically used in combination with other tools, such as a vehicle interface module or a vehicle communication interface (VCI), which physically connects the computer running the GM GDS software to the vehicle’s onboard diagnostics (OBD) system.
