No, you likely won't need it if you don't let the reservoir run dry and allow air into the ABS block and if you have a high level scan tool you can set the block for bleed mode or even better if the tool can do it have it run the automated bleed. It's rare I ever need to actually use a scan tool on an abs car as long as I do not let it go dry.
This is one service worth going dealer to. Few people reported dealer cost $110. Do DIY only if you feel very confident and know what you are doing. There are threads on how people did it. Any screw-up can potentially cost you $3K.
It’s a two man job with Techstream. It’s a bit complicated. It’s something I’m worried to do it by myself too even I’m a diy’er. The price to do proper brake flush is around $350-400 at the Lexus dealers and at the Toyota dealerships. It’s not $110. Last time I paid Lexus to do a ‘brake flush’ was $95. All they did was sucking old fluid out of the reservoir and filled with new fluid.
If you are brave enough to do it yourself, please do a tutorial on the steps. Thanks.
