Isuzu applications have used shared diagnostic hardware with model-specific software. Holden's RA Rodeo bulletin documents selecting Isuzu General Export software for the Tech 2 via TIS 2000. Its software menu also differentiates Isuzu and GM-based vehicle applications. Holden service Techline TL0663-0402.
IDSS and Chevrolet low-cab-forward vehicles
A November 2025 GM bulletin for the North American Chevrolet low-cab-forward models listed in the bulletin states they are no longer supported by Techline Connect GDS2 and SPS, and instructs dealers to use Isuzu Diagnostic Service System (IDSS) for diagnostic and scan-tool support. It says IDSS works with their existing MDI2 interface. This is limited to the models in that bulletin and is not a global coverage statement for Isuzu or Chevrolet. GM bulletin PIT6453, November 2025.
See Holden diagnostic systems and GM GDS2 and Techline Connect. Always verify the manufacturer's current service information, software and interface for the exact vehicle.
