yes. Lights are blacked out in the dash physically (it still throws a "service advance track" error on startup). Abs actually still works (at least im 99% sure it does). Turning the system "off" with the button without turning it off in the tune didnt feel or act the same. Its still got power over the car with the abs module in there but it only does anything if the car is enduring a "severe yaw event" lol.
