    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?

    Car in sig.

    When u tried re-setting did you:
    1)Have key on "on" position
    2)Take one battery terminal off
    3)Wait 30sec-1min
    4)Re-connect
    5)Turn key on "off" position
    6)Start car to see if code cleared

    I think so, but I'll try it again tomorrow, thank you.

    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



    100 post yea

    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

    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.
