I wonder what it could be? Note that there is no CEL. Did a search and another guy said a relay needed to be replaced. Crossing my fingers it's not anything more. It's at the dealership as of tonight.

We'll see.

ROK

They said some type of ABS ECU costs around $6K. This may need replacing. Yikes.

But they also said my brake fluid was showing a little low so I had them do a complete brake flush. My brakes feel firmer now? I had adjusted the height the day the xmas tree appeared and I understand the suspension uses the same brake fluid to operate the height mechanism?

They reset everything and hoping it stays unannounced. I had no idea these ECU parts were so darn pricey.

It's a Lexus!

I hope the problem goes away with just resetting the ECU. Otherwise spending $6k on this is a bit too much.

ROK

Agreed. Hoping it is just the brake fluid, but we shall see. Haven't ran into a thread where a member had to shell out this much for a Toyota part. Insanity.

car-parts.com shows pricing on the ABS ECU between $150 and $400 although I am not sure if the ECU is coded to the car. No way I'd buy a factory ECU at that price !!

CruiserGX

I second that. Have you ever replaced it? I had the same problem, replaced gas cap, problem solved. What's the worst that can happen $25 bucks, do it.

ROK

i'll get it replaced per your advice, but the thing is, mine shows no cel. i hope it's not the master cylinder.

if you don't want to try the oem, $5 or $7 from auto zone work just as well!

Following you could do to solve the problems
1. Goto Autozone get the Fault codes ( it is free )
2. Once you get them put it on this forum, we can help you from there.
3. It is a very rare that the ABS ECU fries, the dealer or whoever said that has to be dumb. Without even trouble shooting and getting the Exact data frames from the ECU , you can't conclude the diagnosis and say the ECU needs replacement. Absolute bull story. ( maybe try another dealer you will get another story)
4. Buy this p/n from the dealer - 09843-18040 ( it a SST tool - wires just plain and simple) $5-6 it cost max.
would advise once you get the codes and the stuff. Good luck, Dont break your head.!!
