So about 1PM today, it'* snowing like an SOB and I have to go out for lunch. I'm 3/4 mile from getting back to work, coming up a hill, when my "LOW TRAC" light comes on for no reason (I don't have traction control, and I was not on my brakes, nor was I driving out of the ordinary.) Two seconds later, the LOW TRAC light goes off and my ANTI-LOCK light starts blinking, along with a warning chime. Sure enough, I hit the brakes hard to test - with no one behind me, of course - and all 4 wheels locked. Good thing they didn't fail WHILE I was braking. ABS worked fine all the way into town and back to work, until the last 3/4 mile.

Any ideas of what might be wrong? I've never had my ABS fail on any other car I've owned. I have to wait until Wed. to get it looked at. I sure hope it'* something major, so I can take advantage of the warranty I bought

Forget the fix , just get full cverage , NOW!

Ok, it can either be a wheel speed sensor, the PMV (300 bucks) or the EBCM (700 bucks). Check all connectors first. On all 4 hubs first, for the wheel speed sensors, and check for corrosion on the PMV connectors under your airbox. The EBCM is located below the stereo on the firewall. Only the dealer can scan these codes, so you're blind until you take it to him. That'* why it'* best to check for the basics first. These systems are very spendy to repair.....but are USUALLY the relatively inexpensice wheel speed sensors. Keep me posted. I've been through all this. Cost me $128 to get mine diagnosed.

Well I'll give you a further "mini-diagnosis". After the car has been sitting for a while (maybe an hour +) I can get in and start up the car and the ABS light is off, all systems work properly. Then, about 5-10 minutes later, as I've been driving the car, the same symptoms appear, ultimately leading to the ABS light coming on again and no ABS function.

The ABS is fixed! Turned out to be a defective wheel bearing - I had a bad wheel bearing replaced 4 weeks ago, and the new unit was either defective or improperly installed. But it'* fixed now, going to pick her up right now.

Thanks for the leads, anyway. Hopefully I won't have to worry about this for a looooooong time....
