Didn't check the brake fluid until now yead yes LS460L

Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far?

No , I recently went to a work shop that checked the problem code , he suggested replacing the ABS module , but I was not convinced by this solution I normally work with workshops , never tried fixing these kinds of issues by myself

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

No , thank you

If you clear the code does the code number come right back? Do you have the vehicle identification number available so I can check a few things?

L-SB-0016-16 the service That addresses this issue on this particular car. If you search that number you'll find a copy of the bulletin online. According to the vehicle identification number that does not appear to be any recalls or warranty extension programs for this that you might want to contact your local dealer and ask for some assistance never hurts to try. Unfortunately I don't have good news. This code that you're getting means that there is a leak between the accumulator pressure cylinder and the actuator itself. It Is an internal failure. There have been multiple complaints and issues with this. The only fix is to replace the ABS actuator assembly/accumulator assembly. The updated or new part number is ***** Please don't shoot the messenger. If you need any other specific information feel free to reply and I will get back to you. Otherwise if you have not done so please do not forget to rate the assistance I provided you today at three or higher and a five would be awesome.
