ABS Light on dash

[TQuentin1]

Welcome Highsmith16. Not sure of the configuration of the 99 LeSabre. My 95 has discs on the front and drums on the rear. The connectors for the front sensors that detect wheel rotation are obvious on the backing plate when you take off the wheels.

Put the ABS light bulb back in the dash (there ya go MT-2500!!) and carried the car over to Brake Check. They plugged in an ABS code analyzer and it had 4 "hard codes" and 16 "soft codes". They believe it might be the module itself or the harness. I had replaced the module back in 04 after hearing that from the Buick stealership. So the BC guys flushed and bled the brakes, reset the codes and then turned the key back on. It went through diagnostics with the ABS light "blinking" lightly, but then stayed on steady.

Took the car over and had it inspected (had been due since January), then went back to see if the module was covered by warrantee. Nope - only covered for a year.

While the car was on the rack at BC, we checked out the front end, and both the inner tie rod ends are shot. So I bought some at O'Reily's and went home to fiddle with that. Jacked the front end up and crawled around to see how hard all that was gonna be. Very big pain in the butt trying to do that on the ground. Have to pull out the rack & pinion assembly to really be able to "git 'er done". Forget it. Changed the oil and filter while under there and then slapped the wheels back on the car, let 'er down, and backed it out! Parts were over $100 for both inner tie rod ends. I am takin it back to BC and getting them to do it, and then align it. While they are fiddlin with the front end, I am gonna get them to check the ABS again to see if it is a different bunch of codes. If so, then the module is suspect or the wire harness. Either way, I will live with the light!! It is the spare car anyway in case my bikes, my car, or my wife's car all crap out.

TQ

I had the ABS stay on in my 97, and the codes pointed to a bad ABS module (sorry I don't have the codes). My mechanic got one from a car recycler only after several tries since the ABS units can differ significantly even in similar vehicles.

I was told that if it wasn't fixed, the brakes would still work, just not in anti-lock mode.

I had a bad inner tie rod too; the mechanic found that when I had the struts replaced.
