So I have a 94 z28 6spd as I was driving home today the abs inop, brake, and low trac lights all came on for about 10 seconds then turned back off. My car is running great but what would cause those lights to turn on?

 

All of those are connected. Mine does it and the brakes will go all the way to the floor for a second or two and then if you don't slowly let back up on them it will slam you through the windshield. Seems like it was wheel speed sensor or something. Put the low trac in search field on here and you'll find some topics on it. Mine has done this about 4 times this year.

 

most likely a front wheel sensor or sensor harness failing. being its your brakes i would recommend you have the abs system scanned for codes. also, if the abs itself is failing you can have strange peddle action.

 

Hm alright I'll have to pay some close attention to my brakes.

 

Was it raining? I get it once or twice a year mostly during or right after a heavy rain. I assumed its a bad connector. I have not worried too much about mine because I felt no effect on the braking. If I felt the ABS cycle a few times I still would not worry too much but if my pedal was going to the floor I would figure it out quickly.

 

I don't remember the first time but it was damp outside the second time they came on

 

I had this happen to me in the snow. I figured that I got too much snow up in the wheel area because it came on right after I ended up sideways because some idiot in a 4x4 lost control and I had to swerve to miss him hitting me. My lights went off and my ABS worked fine a few miles later.

It just came on again twice today about a minute apart and its bright and sunny, brakes never messed up tho every thing felt great.

 

Were you braking when they came on? May just be a faulty sensor. My ABS INOP light was on for several months at one time. They took a sensor off and put it back on and it hasn't come on since then.

 

had the same problem last year. they would come on/off through out the day. then never saw them again. car ran/runs like normal.
