Reset my MIL with DIY code reader or need TIS Techstream?

[D&D]

I've currently got this issue (TSB) with my car:
T-EG048-07(M.I.L. ON DTC P043E, P043F, P2401, P2402, & P2419)

It's causing a MIL, and my inspection was out last month. So ASAP, I'm planning on getting a good used charcoal canister assembly from a 2008+ Yaris and NEW OEM fuel tank filler pipe cover and cover holder.

Now I have a pretty decent OBDII scanner. I know it can clear my codes because I've cleared the above listed codes a couple times just to see if I could (only for them to show back up as expected a day or two later).

My question is, if I replace all the stuff that's mentioned in the TSB, will clearing the codes with my reader be good enough, or is there something that the dealer would do with TIS Techstream that I can't do??

TIA
