2004 GX470, started the beeping alarm and abs brake light. Scanned with tool and got these codes.

Considering replacing the unit myself. Does entire abs unit need to be replaced or would just booster motor replacement suffice?

Would control module need replacing too?

any insight greatly appreciated!

 

here is the alarm sound. any chance this would just be the brake booster? or anyway to check that?

 

I think it depends on what sort of shape the valve body and ABS block are in. If you've been good about changing brake fluid every few years, they're probably fine on the inside.

There’s a guy on eBay that rebuilds these, we did this last year and very happy with the results. In our case we were pressed for time and simply bought one he had on the shelf and sent in my core. Cost a little more, but was worth it for me.

thank you for the recommendation! i actually did reach out to him but he didn't have any available and also can't wait for the turnaround.

picked up a refurbished brake booster and accumulator and going to try to put it in next week. hope it fixes it!
