There's an ECU for the braking system too. Did you check to see if any powering is reaching it?

I believe the ECU for the braking system is located in one of the kick panels (don't quote me on that).

The ECUs I've witnessed over the years on this forum do go out every once in a while.

My buddy who had a 06 GS300 had his fail at like 99k miles, car was luckily still under warranty and Lexus took care of it (I believe the bill for part alone was $2300).

Either way GL and keep us updated!

I would take it back to the dealer that replaced the ABS and tell them to inspect it. I feel the abs module went bad.

The car was at the dealer for 2 weeks they could find out what’s wrong with it but they said they can change the abs module and the harness for 8400$
