Hello!

As you know, for newer Toyota (MY 2021 - ) after ECU replacement, it is important to confirm if ECU security key writing is necessary (Toyota T-SB-0111-20).

My question. What level of subscription to TIS (Standard or Professional Diagnostic or Security Professional) is required to complete this procedure correctly?

I need to perform this procedure for Toyota Venza HV a'21 VIN JTEAAAAH1MJ031202.

Thanks Vlad.
