anti-lock brake light

[stoneymonk]

This morning on my way to work,coming off the highway on the offramp my anti-lock brake light came on,brakes work fine fluid is at proper level.After work light was off only to come back on again,thinking could be a sensor issue?where is the sensor located?,can i reset puter by disconnet battery to reset?.Thanks all for your inputs.Tazz

more often than not, it's usually due to the power supply to the EBCM being interrupted, and i believe it gets it's power from the remote boost terminal, so take that apart, expose some fresh metal for the EBCM get power from and check to see if it happens again.

either that or check the MAXI-fuse for it in the underhood electrical center (#2 IIRC) and see if the terminals are corroded or a connection is unstable, or a bad wire, etc, etc...

if you need wiring diagrams, let me know.

Hey Robert,where is the ebcm located and alo the sensors for the anti-lock?.

the EBCM is the little electronic box on top of the master cylinder. should have a pair of two or three wire connectors sticking out of it. you can't miss it. and the wheel speed sensors are VERY close to the braking hardware. i can post up a few drawings of it if necessary.

CRAP! wrong part. the EBCM is behind the left hand side of the dash.

and a better description of the wheel speed sensors is that they are RIGHT next to the struts.

Good thing i didnt take anyting apart.Now the ebcm is it on the left kick panel or under the dash,what does it look like?

[robertisaar]

i could have swore i already posted this...

but from what alldata is saying, it's up in the dash, not the kick panel of the door(unless i'm using the wrong term here...)

if the ABS light is on i would look at the Wheel speed sensors before anything... the fronts are removable and the rears are built into the hubs... everytime my ABS light was on is because of a bad wheel speed sensor..

Well the light is off and everything seems to be working good for now,i only pulled the fuse for the ecm.

cool. mine was on and off randomly, then became more often then not. ended up being rear wheel speed sensor/hub and it hasnt been on sence i repalced it.
