Default ABS code is C1253 no other codes present?

Lights came on the dash for abs/vsc. I hooked up the tech stream only to get this code c1253.
I will pull the codes again tonight when the wife gets home from work.
Taking the car into the shop tomorrow at 8 am. Currently, I checked the fuse like tech stream shows but I have not checked the abs relay. I have not tested resistance on connectors or wires anywhere.
I want to know if anyone had this specific code C1253 and what fixed it?
My car is a 2007 ls 460
PLEASE don't ask questions that are off-topic!
Please reply if you have fixed this specific code and can share how you fixed it.

Most likely, your brake actuator has an internal leak. This is a known issue for LS460 model years 2007-2013. Lexus solution is to replace the brake actuator with the latest model Part Number 04003-45450. Please see the attached PDF file for details. However, since your car is long out of warranty, you may try the "Actuator has been removed" brake bleeding procedure first and see if it eliminates C1253 code, because air in the brake actuator also causes the same trouble code C1253.

Thank you for the update. Hope that it is the cause for the problem. By the junction box, did the tech mean that it is the engine fuse holder junction box Part Number 82620-50100?

Default Update # 2

Yes the tech had the junction box with the abs fuse that's not accessable sent over from the dealership $500 part.
Now the issue is the tech can't initialize the abs. The tech is on face time with a master tech from LEXUS.
It's a bummer no car for the 4th of July weekend🙃
Then the tech tells me it's throwing codes for power steering a lot of new codes🤣😂🤣
I'm hoping come Monday the tech can get the car to read the initialization for the abs. I'm keeping my fingers crossed.

Default Update#3

Okay so it's been about 2 months everything's been good until last week.
Abs lights on, VSC light on and brake light comes on. No buzzer alarm for ABS.
I check codes with tech stream and only code is C1253. I've changed the abs relay located next to the accuator side as it wasn't in spec. Car drove for five days no lights. I noticed when it's cold outside and I press on the break and start the car the abs come on when car is placed in drive.
I can press the brake 100 times on first child start with car running.
It's not until I put the car in drive does the abs light come on.
Please understand this happens only when it's cold out side and doesn't happen all the time. When I press the on/off switch three times on a child first start and the crank the car on the fourth push start I never get the ABS lights on the dash.
I'm thinking it's electorial as the info I'm reading tells me during the C1253 could be the wiring harness or grounds and connectors.
If anyone can tell me the ground I should be checking would be great.
I do have the wiring diagram for the entire car but I don't know how to read it.
Any pictures of the ground points for that harness the skid control and accuator are on?
I was told there are ground points behind the drivers side tire and they are know to go bad and break lose.
Any pictures of these grounds would help.

Hey guys, just letting you know that i have the 2007 LS460 with code C1253 and after struggling for 2 months, I finally got it fixed. I had to replace abs actuator part #04003- 45450 (latest updated version). Before that, dealer replaced with 2nd verion and car ran for 1 week and code came back. Please don't waste your time like me ... install that last version !!! btw, i also replaced abs pump as it will eventually fail because actuator issue. Parts and labor for both was $3300 at Toyota dealer (i bought parts from Lexus) ... hope this will help you.

Mine has only C1253 and the abs lights and vsc lights come on. I flushed the brakes and so now it has new brake fluid. No change and clearing the code only is temporary. It comes back when I press the brake. I went through the diagnostic for the code and it said replace engine fuse box 2 which is part number 82720-50081. Found a used one at the pull a part. Cleared codes and it hasn't come back. Hopefully that fixed it though Lexus would have replaced the actuator according to their recall.

I'm curious if the leak is caused by old contaminated fluid.
