I have a 94 civic with ABS.When braking from low speeds the abs will self activate and pump the brake pedal.Also sometimes it sounds like the abs pump is trying to bleed itself(that buzzing noise).the abs light came on once and went out,not sure how to pull codes.If anyone has had this problem and knows a fix any info would be greatly appreciated

 

To pull codes, jump the connector under passnger kick panel. Same as checking engine codes

 

ok.now has anyone else had this problem?

 

Your ABS sensor may be dirty or loose/out of place. I would check the sensor to see if it has come loose and if not take it off and clean it. Your ABS light may have come on/off because of this and the pulsing may be because its loose and out of place (happened to me on my truck)

 

I actually cleaned the front abs sensors they were dirty and I tought it would help but the abs is still kicking in for no reason


Anyone with info please help

 

anyone?

 

Critical question no one has asked yet: What wheel/tire combination do you have? Mismatched or grossly incorrect wheels/tires can cause the problem as well.

 

i have 99-00 civic si rims with 195 55 R15 tires,never had problem before and i don't think that would cause my abs problem

 

okay i jumped the connector and got abs code 4-8 wheel sensor LR
I found the connector for the LR sensor and disconnected it and the abs system is no longer pumping the brake pedal.That must mean the sensor is sending the wrong signals to abs computer right?
