I have read almost everything on the issue, but most if not all is in regards to having "1)Brake 2)ABS INOP 3)ASR OFF" lights all on together.

I had this issue where all three were on, had it read and low and behold ECBM failure.

I bought a used one off a low mile 01 z28 with traction control( I have a 01 SS with traction control) Anyways the replacement worked, no lights fully functional abs and asr.


well i took a right turn quickly and two of the three came on 1)ABS INOP 2)ASR OFF.

I got home disconnected the battery, took out the abs fuses etc.. let it sit for 20 or 30 mins and reconnected everyting and they were off. A couple days later i took another turn quickly and they came back on and have been on since.

My buddy that works at firestone that scans my abs for free is out of town so i cant get it scanned right now.

ive checked the grounds, i cleaned and tighted the speed sensors in the rear wheels.

what all can i check because this only has occured after turning at fast speeds.




could it be any of the following:
low tire pressure throwing the speed sensors off
bad abs fluid(I havent changed it in over 5 years)
the passenger speed sensor wiring since it has like an extension it plugs into?


i will check anything you guys can point me to because im stumped

Do you have the stock wheels?

Have you checked all for wheel tire pressures?

What did you do to your old ECBM?

Do you still have it?

I want to see if I can fix them.

No i havent checked them, but none of them appear low.

i have the old ecbm on a shelf.

Did you figure it out?? I'm having the same problem. I Already did the basics. Is there a way to test the abs/wheel speed sensors? They're kinda salty to just buy w/o testing them for a shot in the dark.

ive had my two lights on for a while also i changed the wire harness on the back of the wheel hub and they went off and work fine

Get someone with a good scanner they can watch all the speed sensors while driving and try to duplicate the prob

All you guys with ABS/ASR/TCS Dash lights on, get your car scanned first and post your code(s) -- it will make figuring out issues that much simpler! Advance Auto scans ABS for free!

I was able to get my abs scanned but eve after clearing the codes and replacing the pump my lights were on.. They were on this morning also they just turned off when I went to lunch today and have been off since

They're back on.. Now

For this to be happening when it would turn off then on then off... It sounds like a bad connection somewhere, right?

I keep reading about 3rd brake light causing alot of problems, I haven an SS so it doesnt have bulbs it has the LEDs...is there anything to check in terms of that?

What was the error code?

ok this has been a 2 year problem...but i have only recently tried to really get to the bottom of it.

First I had all three of the lights on, I replaced the damaged pigtail on the front passenger speed sensor...no luck

Second I got it scanned and the code c0550 came up, so i replaced the ABS brain. The lights went off for a couple days then came on.

Then they came back on and i got it rescanned and this time it was a c0110 and I replaced the pump portion of the ABS.... the lights went off and everything was functional...but they turned back on after a day...


I cant get it rescanned as my buddy with the scanner is out of town for the next month and im not trying to pay $50+ to get a code so im really trying to think of anything else....

I have a multimeter, could i use that to test the sensors?

I was unaware that Advanced auto had scanners capable of reading brake codes... I mean i know they scanned but i thought it would be for just the engine stuff.

Went to advance auto on my lunch break and not all locations have the scanner capable of reading abs codes, so i will try a different location when i get off.

I could be your wheel speed sensors in the rear, take them out and clean them really good. If that doesn't fix it then they will need to be replaced. I had the same problem.

I went to 2 different Advance Auto stores yersterday and both times no code was found... but my ABS INOP and ASR lights are off

Seriously? I have an issue in my DD. My understanding was unlike OBD codes, ABS/TCS systems aren't really standardized yet, so there isn't a common protocol. As such, it's kind of a pain to have them read.

If Advance can do this, I'd be thrilled!
