2004 Gen II - New Battery - Now needs new ABS Actuator?

I would see about getting a used part. Since that's a lot of money to spend on a 9/10 year old car.

 

I think it may be a relay that's faulty or software that need's updated.

Right. And I might start dating Calista Flockhart. That's the ABS actuator for another $3000-$5000.​

=============================================​

Ed Hornyak's view of reality: "I personally believe that U.S. Americans are unable to do so because, uhmmm, some people out there in our nation don't have maps and uh, I believe that our, I, education like such as uh, South Africa, and uh, the Iraq, everywhere like such as, and I believe that they should, uhhh, our education over here in the US should help the US, uh, should help South Africa, it should help the Iraq and the Asian countries so we will be able to build up our future, for us.”​

 

Two ideas:

1) Do you have any driveability issues at this point? If not, and since no skid control ECU warning lights are on [such as ABS, VSC or ((!))] then why worry?

2) If the problem gets to the point where one or more of these warning lights come on or if your brake system is impaired, then buy a used part from a salvage yard, as previously suggested.

I think it is likely that the brake pressure accumulator within the actuator assembly is leaking pressure, hence the need for the brake pump to run more than in the past.
