Just picked up a 2002 LX 470 with 196,000 miles on it down in Florida. Paid $21k (steep, I know. It’s very clean though) and got the abs, and brake lamps with the buzzer the day I got it home to Ohio. Definitely not what I wanted but it seems to be a fairly common wear item on these models. On cold starts the abs booster pump will cycle off and on then the warning lamps and buzzers pop on. I can let it sit running for a few minutes and it’ll eventually fill up and drive fine. As the motor is a wear item, I’m not gonna risk a used one so I picked up a new brake booster pump and accumulator p/n 47070-60010 from camelback Toyota for around $1k with overnight shipping. Ill throw it in and update. Good to be back with fellow Toyota owners again.
