This is most likely an SFD vehicle. For special functions like inspection/service reset, the SFD security gateway must be unlocked first.
You have to purchase SFD on an annual basis. You can purchase the SFD token in the device “Mall” or directly purchase 1-Year SFD unlock license from Topdonshop.eu. Then log in with your TOPDON account (with the token) and unlock the gateway to perform the reset normally.
