Does one need to pay a yearly fee to keep the software working? Obviously it was not a native English speaker who wrote that description.
Hello. Per the vendor:
When you purchase the THINKDIAG new, you receive one free year of software for one manufacturer. After that year is up, it is $39.95 annually for the software per manufacturer (ex. Chevrolet, Toyota, Honda, etc). If you decide not to renew, you can still use the tool for basic functions like check and erase fault codes.
