OEM Diagnostic
TIS2Web is the online GM / Opel-Vauxhall service portal that hosts the diagnostic and programming toolchain — GDS2, Tech2Win and SPS/SPS2 — plus service information. For Opel and Vauxhall workshops it is the gateway to run guided diagnostics, read/clear DTCs, perform live data and actuator tests (via Tech2Win or GDS2 depending on platform age), and reflash modules through SPS2 using GM's validated calibrations. It connects to vehicles via a GM MDI or Tech2/passthru interface and requires an online subscription (GlobalConnect/GlobalTIS) for programming and calibration downloads. Independent Opel specialists use TIS2Web to access dealer-level functions across Corsa, Astra, Insignia, Vivaro and related models, including pre- and post-Global-A architectures.
TIS2Web is Opel's OEM diagnostic and flashing portal; Softechpro complements it on the tuning side, editing the extracted engine calibration for DPF/EGR/DTC-off and Stage tuning with automatic checksum correction.
