Please help: Solve ABS Code #1 - Honda Prelude Forum

InterludeTypeR · 03-14-2010, 09:02 PM

I pulled a ABS code 1 (motor over-run) for a 4th gen. Is the ABS motor really supposed to run for a short time when you have the car running for a couple minutes because I have never heard it running before? The ABS reservoir is filled to the max line with fresh fluid. No problems with braking or anything after I changed to BBK in front and new calipers/lines in the rear with new properly bled fluid throughout.

I followed the Helms and tried to bleed/relieve the pressure by loosening the nipple bolt attached to a drain tube but I can't seem to get much fluid to come out. There was just may be 10 drops and a bunch of bubbles and that's it. I tried to do it with and without the car being on and I can't get a single drop anymore after that. I jumped the ABS motor relay in the fuse box for 10 seconds a couple times and the motor runs smooth and quiet so the motor is fine.

Can it be the pressure switch that's gone bad or the ABS relay or am I missing something else to do??? Is there a way to make the fluid come out by bypassing the pressure switch?

Please help!

Thanks so much!!!

if u see bubbles that means theers more air in the lines.
to make it come out more have somone pump ur brake ( make sure the engine is running)then hold it down and unscrew the nipple bolt till the fluid comes out but dont release the brake pedal till you tight the bleeder bolt keep repeating this cycle till you dont see anymore bubbles left, and do that to which ever brake u replace, as fo rthe abs you might have a bad sensor somwhere that cause the light to come on mines does that too but i aint too worried i have other situation to take care of, the abs would be my last issue

Bleeding the ABS unit is not the same as bleeding the brake system at the calipers

I don't even think you can bleed your own ABS system, you have to take it to the dealership.
