ABS Issue without code

[sn95gt50]

My daughter complained that the anti-lock brakes are kicking in when braking, more prevalent during cornering. She is not getting any kind of indicators on either the dash or the DIC. I assume that I have a sensor going bad in one of the bearings, but, how do I determine which one. Any diagnostics I can perform to at least narrow it down? Or, anything I can check?

I did a search and didn't find much.

Thanks in advance,
John

I have the Torque App on my phone for my OBD II Elm 327, is it possible to get individual wheel speeds

You will probably require a scan tool that can read the ABS module and it's functions. As far as I know you can't do that with the phone apps.

ChevroSys Scan Free - Apps on Google Play this app will read abs codes. sounds like the abs module has gone bad. the abs will pulse under your foot when driving slow like trying to park.

Found it, surprised it didn't throw a code. Found electrical tape on the abs sensor wires where it was secured to the control arm. I removed the tape and found that a new connector had been spliced in, different colored wires. The connections were very corroded. I cut out the crimp connector and cleaned it up and reconnected and sealed up. Took a test drive and no pulsing any more.

Gotta love free fixes.

Thanks all!

i was going to say it seems like a lot of abs code things come from the front-where them wires move a lot and theres more weight.

I agree, started front DS, nothing stuck out, then front PS. Still no signs of the symptom, still surprised if didn't give any indications via the DIC.

Thanks all,
