LS460 abs vsc system problem

I got my 2007 LS460 with 59,000 miles about 6 months ago and lately this ABS, VCS, Tire lights kept coming on . Took it a local Lexus expert Mechanic and he said it is the Brake Actuator (code 1253) and we replaced that . After a couple of weeks the lights popped up again and this time he changed the Engine room power computer and it again after a couple of weeks, the warning lights came on but this time they go off and on every other day. So took it back and he checked the wiring at skid control ecu and pump and all good. pin fit seems good. removed cover for the pump power input and resistor for signal to skid ecu and added some solder to resistor to circuit connection in case of poor contact. Sadly after a good 2 weeks again the light comes on and ones I shut down the car they lights go away until a day or two and they come back again. Shut the car down and a day or two/three days later they pop up. Can you help, please.
For me it was the abs speed sensor or whatever the name of the part is, it is part of the wheel hub. Cannot be purchased separately either from Toyota or aftermarket. I had to deal with this problem but I do not remember what happened with it, somehow they managed to fix it.
You can see the black plastic part with the connector, try having that opened up, checked and cleaned with contact cleaner etc. Also if you have a device that can read codes, you can see if it is reading data and sending data while on the move, that should tell you if it is broken or not.

Hi my friend..
after replacing the abs sensor in my 08 ls460 the lights went away for some time then they came again and the brakes stopped working so I took it to a lexus expert mechanic and he replaced 2 parts ( brake actuator assembly + brake booster pump assembly)
I bought the actuator for $2000 and brake booster for &1000 all original parts from the dealer
then I asked about this problem they said that its a manufacturing defect in 07 08 09 10 Lexus ls models and they replaced it with another enhanced actuator in 2010 (when too many customer complained)..
the brake booster pump will fail if the actuator failed and you keep driving the car..
so its important to quickly replace the brake actuator..
but my advice is to replace them both at once so you can forget about this problem happening again..
you can replace the actuator and booster in any shop specialized in lexus.. just replace the parts and add blake fluid and then bleed the brakes after that you should have a toyota computer/tool its called toyota IT2 (intelligent tester 2) to program the car it will take 2 minutes to complete the programming and you are done..
I paid almost $350 for that mechanic for fixing and programming..
I will post spare parts picture after a while..
thanks..

I have a 2010 LS 460 L my ABS traction control brake lights came on and the brake is hard when pushing down it only has 86,000 miles on it but the problem is it has a rebuilt title which the vehicle was salvaged I wonder is the warranty still covered through Lexus since so many people have problem with this issue

2010 Lexus LS 460 L ABS traction control brake light on
I have a 2010 Lexus LS 460 L it’s 86,000 miles on it
Rebuilt title my brake light ABS light traffic control lights are on and it’s beeping constantly and hard to break I see so many people with the same problem seems like the dealership covers most of them for the brake booster and actuator Is it possible that my vehicle is qualified for the warranty because it is a safety issue is Lexi still going to honor it
