Here is the guide to install GM Opel Tech2win from PSA service box. PSA Group
has added the Opel/Vauxhall Tech2win subscription as standard included in the
GDS2 Subscription.
This works with Passthru tools such as
vxdiag
vcx nano gm, drewtech Mongoose GM, Drewtech cardaq, Cardaq m, Bosch KTS and
even Ford VCM3. However it does not work with Autel Passthru :( you will need to
make sure the relevant drivers are installed.)
Then go to
Service Box. You MUST use Chrome as the browser and NOT
Edge, Explorer or Firefox. For some reason the Java doesn't run properly on
those.
Purchase Opel/Vauxhall Legacy & Chevrolet Subscription
You'll need to purchase subscription for SPS programming.
