ABS lights ??
my old man said the 99vert auto 100k miles had the ABS light, trac system ect lights come on today for about 3 miles then go off. I have had them go on before as well. Out of 50k miles we have had it, it might have hapend 5 times...Any hints?

Well would the system give codes if the light went off? He said the abs light and trac system flashed in the digital area then went off. There are no lights ( ABS or check engine) on right now.
Has anyone ran into this before?

Well i used the search function for the first time in 4 years and found out its not a big problem. Either wheels spun on rough road/ rail road ect or loose speed sensor at wheels. Will check it out ..
Thanks

You're right....checking the codes is a waste of time.

There are a lot of post's on this subject and a 99 with 100K is probably due to a clogged BPMV pump. This pump gets tested everytime you start up and if it does not run correctly the code gets posted telling you to service the unit. Pull the codes and search the forum.

I don't mean to come off rude but you guys did read I have no codes right? The check engine light came on, then abs, trac lights came on all at the same time. They went off 3 miles later. I checked and have no codes.
Thanks for anyones help

Sometimes you have to shake some of the harnesses with the car on to see if it throws a code, etc .... which will lead you you to the problem.

The IPC display, the 20-character, vacuum florescent screen above the steering column that says "Corvette by Chevrolet" every time you turn on the key, is a powerful device. DIY Service Techs are going to be most interested in the IPC's ability to show diagnostic trouble codes (DTC) for all the modules that transmit them.
The "diagnostic display" mode is entered with the following procedure:
1. Turn on the ignition but don't start the engine.
2. Press the "reset" button to turn off any warning messages
3. Press and hold "options" and
4. While holding "options", press "fuel" four times within a 10-second period.
Inititially, the on-board diagnostics go into the "automatic" mode which shows each module's DTCs in a pre-set sequence:
