ABS INOP and ASR OFF

Hello,
I jacked up my 2001 Z28 yesterday on jack stands front and rear to inspect the brakes. I ended up only removing the tires on the passenger side. Today I have the lights mentioned in the title. I checked all the fuses, sensors and wires. Everything looks good. I'm sure I did not jar or pinch anything when I jacked the car up. I am suspecting one of the sensors went bad because both the ABS and ASR would rely on them. Any ideas? Am I on the right track? How do I determine which sensor is bad if in fact that's the problem? This type of thing annoys the h$#l out of me. HELP!

Problem solved. Woohooo

Glad to hear that you found the problem.
I'm having same prob....
what did you find wrong?????

I left the -ve batt lead off for a day, then the lights went off after driving about 10 feet. All has been ok since. Only thing I think of is that I reset something (computer?) that got confused because one of the sensors read a different position. I dunno !!! I'm jus an old hot rodder. These cars are waaay ahead of me.
