Need help ...my abs kicks in almost every time I brake just before a complete stop...mechanics are telling me no code so it's hard to diagnose problem....also hear some sort of rubbing when I accelerate almost like brake pads are slightly rubbing on roters... new brakes new front roders.... all way around new calibers...rear roters are not new....could I take out fuse for abs to disable it until I find someone who can diagnose problem

Seems like a no brainer but did anyone check the condition of the front hub bearings while the rotors were being replaced?

yes, you can pull the fuse to disable the abs. all works fine, just no abs. so the wheels can lock up now if your ******* them.

i pulled the abs fuse in my regal 7 years ago cause it was acting up past my will to fix it. it stops better all around even in snow.

if a ebcm was the fix id have done it, but its a bad wire or some crap.

the shop use a abs scanner for codes? a lot of the time when the ebcm goes bad you are unable to connect with the abs scanner. first solid clue the ebcm is bad. other then the slow speed engaging of the abs, like slowing to park, or coming to a stop.

for reference its located under the drivers seat pretty much tucked next to the frame and under side of the trucks body. brake lines run to and from it. new they cost a arm and a leg. there are laces that rebuild them and they test em first, so if they test good they wont fix it and your only out the shipping. they run about 100 bucks or so for the repair. or a junk yard would be the next step. be rather cheap there.

iirc theres a vid on yt where a guy shows the repair, the board gets some solider points broken off. so if you can solder you might want to open it up and see if you find it busted like the vid shows.

found one fast enough

Get the hubs checked. It could cause the rubbing noise if they are bad enough.

What year is your truck?

The typical repair when people open up the module is to repair the solder joints that affect the power supply to the module which is always accompanied by (If memory serves me) the C0265 code and the brake and abs light on.

No code would lead me to believe it has nothing to do with the module. If it completely stopped communicating it would most certainly set the warning lights.

Was a recall long time ago....prob a tsb on it. Front abs sensors on had to be cleaned or swapped...dont really remember. my 01 did it and it was repaired under warranty.... feels like you aren’t gonna stop then it does...
