  • New Diagnostic Application Software required for GM Global Architecture (Global A) Vehicles.
  • GDS & GDS2 is software which runs on a specific PC
  • VCX Nano supports both GDS & GDS2. GDS2 works similar to the original GDS, but faster and easier to use

GDS2 Provides the Following Capabilities in Multiple Languages:

  • 1: Read codes, code status, Freeze Frame data and Clear Codes.
  • 2: Read VIN, ECU part numbers and software numbers.
  • 3: Record, store and replay Stored data.

  • 2: Increase reprogramming speed 20-70% and get ready to service new models

For pass-through programming of electronic control units on all vehicles built since 1996 and future model releases. The VCX Nano is up to 70% faster than the original Tech2.

Example: On a new Tahoe hybrid with 7 ECUS, it would normally take 2 full hours to reprogram. But, with VCX Nano the process is completed in just 45 minutes. That’s a 64% difference and means you could service 10 vehicles rather than 4 in an 8 hour day!
