Does anyone know how to reset an ABS ECU?
I tried disconnecting my battery for about two minutes, no luck. I broke a sensor while replacing a rotor. I replaced it, and the light hasn't gone out since. Is this a Honda dealer only thing?

When u tried re-setting did you:
1)Have key on "on" position
2)Take one battery terminal off
5)Turn key on "off" position
6)Start car to see if code cleared

I also am going to remove my battery backup for my alarm, which is why I turned my key on. I wanted to make sure it wasn't leaking any power over from the alarm backup to the ECU.

I totally disconnected the ABS ECU for 24 hours. I plugged it back in and I still have the light in my dash.
I know which sensor I broke, since I hit it with a hammer. I replaced that sensor and can't get the code to clear. This is pissing me off.

yea tab it is a dealer only thing they have the scanner to reset it. it is a pain but thats life
only other thing to try is dis connect battery then put the 2 cables togher for about a minute theat will sometimes clear the system completly. if that does not work take it to honda

first of all what model honda are u driving????
the abs ecu use a nonerasable type of memory u can disconect it for 5 years and it wont forget the code
assuming youre driving an 96 - 00 model heres the procedure
1.locate your cars ecu (the main ecu that cntrols the engine,usually on the pasenger side ) ,ON TOP OF THE ECU YOU SHULD FIND A BROWN AND BLACK FEMALE CONNECTOR JUST LYING THERE,usually it is covered with a green cap..This is your diagnostic port.
2.Next ,take a short piece of wire and bridge this female connector,ie.the brown wire must connect to the black vice versa..
3.turn on your ignition , dont start the car,,now youre abs light on the dash should start playing morse code,these codes explainn what the precise problem is eg.1long flash 1 quick flash = disconected or failed fr wheel speed sensor.
4. to reset the abs ecu turn ignition off ,STEP 2 depress brake pedal,turn ignition on STEP 3,the abs light will go off after about 2 seconds. STEP 4 .after the light goes off release the pedal,the light will then come on after about 4 seconds. STEP 5 when the light comes on press the pedal again STEP.6 the light will go off again,the relase pedal.
the light will now blink a number of times to confirm the code has been erased
SOUNDS COMPLEX BUT THE PRESSING AND RELASING BECOMES INTUITIVE AFTER THE SECOND TRY
This will work asuming u drive a similair model to mine,let me know how it goes
always beleive you can

Problem still there. I tried the brake/no brake/brake/no brake thing. It didn't work for me. I'll probably have to take it to honda.
I can make the light go out by disconnecting the ABS ECU main plugs, but it won't fix the problem. I replaced the sensor I broke. The problem is clearing that memory, and letting my ABS work properly again.

From B's post:
This is how i reset mine i'm pretty sure.
Worked good, but you might have to try a few times because you might go too quick like i did, and have to start over.
