ACC/Pilot Assist Modification precautions

[vcorusa]

Some info regarding PA and ACC. Till MY 2021 there were 2 types of hidraulic units. "weaker" and "more powerfull". They located on the left side, close to front left wiper. To check, wich one You have-open the cover to access brake fluide, then put Your phone on stick (or, if You have long hand) insert it there with camera on, and try to record video on unit's pump side. If You see 772 - old "weak" unit, if You see 774 - You good to go with acc activation and it will work smoothly.

@MarcoPolo This is what I have manage to find near brake fluid. Does any of these reference to hydraulic unit?

I guess second photo does, but I have 2020 XC60 from Germany, so not the same like in your post.

Your car is PHEV?

It is mild hybrid, Diesel + 48V self charged battery.

Mild hybrid, 2020, that looks like the "Brake by wire" unit. There is no physical "brake module" in the traditional brake system models, it's inside the VDDM unit which would be the electronics attached to the brake hydraulic unit.

Anyways, easy way to tell, check the ECU list on "ECU Tools" tab in OrBit. If you see "BCM2" in the list, you have the "brake by wire" system. There is no diference between car with or without Pilot Assist if you have the BCM2, you can enable config with OrBit ;-)

Thanks, I have already purchased OrBit  , waiting on cable to arrive from US, will keep you all posted...
