Tis2000 is only used for SPS programming, and the Tech II is put into pass through mode when using such. It’s very unlikely that anyone would have this legitimately unless they were a dealer as it’s supplied and supported by Vauxhall and isn’t cheap, therefore if people have this or offer to sell it then it will more than likely be a counterfeit copy which is why we don’t allow discussion of it on the forum (it’s in the rules ) TIS (Time in Service) 2000 is the Vauxhall Dealer’s official diagnostic software for all of the Vauxhall range.
