ABS Light always on even when disconnecting battery then reconnecting car is 97 z28 auto
I have scanned the codes and nothing for brakes/abs. 275/40/ZR17 TIRES. stock diameter far as I know. third brake light works as I have heard this can throw it but I did disconnect it to detail the car for a while but reconnected it is still on before and after.
Have not done any work on the brakes recently but I want to get this solved..any ideas?

check the fluid level in the brake master cylinder resevoir. There's a sensor that will illuminate either the abs, brake, or check gages light. Disconnect the plug to the sensor and jumper the plug with a paper clip or something and see if the light goes out, worst case is you have a bad sensor.

Most generic readers don't read ABS codes. If your fluid level sensor was bad the RED brake warning light would be on. I would look into wheel speed sensors, could just be dirty or bad wire. Most high end scanners like a MODUS or of course a TECH2 would tell you exactly which one.
