Replaced ABS unit, why am I still having problems?! - Honda Prelude Forum

OK, so my ABS unit broke (that $1400 part that tends to go bad on a lot of ludes). I won the auction above and replaced my old unit with the one you see in the link above (not the ABS ECU but the one on the right). It was a bit** to get it out and put the new one in, especially because Honda for some reason decided to switch around the hose entrance on the unit for the pump, meaning a black hose with two banjo holes was too short so we had to do some cutting to make it reach (im positive we didnt break anything). Not to mention those annoying brake lines.

Anyway..

So once everything was put back on, I had absolutely no pressure on my brakes so we bled the brakes for like 30 mins then finally got all the air and fluid out (we didnt bleed the ABS unit). Same thing is still happening though, ABS light is turning on like 15 seconds after I run the car and I have no idea why. The seller on ebay assured me the unit was working fine cause he drove the prelude. Could it be another problem, like a sensor?
Any help would be appreciated.

my abs and brake lights were about 15 secs after i turned on the car also, but it wasnt much. After a week of troubleshooting turns out, i was just low on brake fluid. So i filled it up and it went away, pretty weird, but it fixed it ! i m sure you checked your fluids and all, so maybe take it to someone who can give u a complete diagnostic of the problem.

if after bleeding you regained pedal feel and it brakes, but the light still comes on, you could have a faulty sensor in one of the wheels, I'm pretty sure anyway that alone can trigger the ABS light.

Only thing I'm worried about w/ my non-working (never has) ABS is if/when I resell my lude.

You really need the Helms to properly troubleshoot the ABS system. It will save you $$ in the long run.

hey can you just remove the ABS ECU if you dont want your car to have ABS, cuz mine just doesnt work anyways.

I thought about it, but it's not really gonna save you much weight, or anything.
