Ihad to replace the ABS unit & the abslight is still on what do I do

If there is an ABS issue it will turn on the red brake light as well. Were these lights on before the repair? You can try disconnecting the battery to see if the ABS resets. If the lights come back on you will have to have a scan test performed on the ABS system to isolate the problem

Hey, it should be able to be reset. I have a 2005 Chevy cobalt and Ihad the same problem but my manual told me how to clear it up, so you should check in the manual to see how.

Bad abs sensor you can pull the abs fuse under the hood usually large amp fuse 40-60 amp abs wont work put brakes will function better till repaired

On the ABS unit is a bleeder valve just like the ones on the caliper, blead it and it should be fine.

Fuse 12 (10 Amps) may be burned out. Its located in "Junction Block". Losing
fuse 12 would kill the ABS systems and light the ABS dashboard light.

Fuse 11 (20 Amps) may be out. Its located in "Power Distribution Center". Losing fuse 11
would kill the brake lights, and light the ABS dashboard light. If fuse 11 is blown,
check your (3) brake light sockets for shorts of any type, or fuse 11 will just blow again.

Here's your ABS Indicator Light wiring diagram:

Check your parking brake. if it goes down to the floor or does not hold, then your back brakes needs adjusted. bad master cylinders bleed off slowly to the floor while pushing on the brake pedal. If you need assistance on adjusting let me know.

could be, check brake fluid, if you have computer scaned you will be able to pinpoint problem, may be a sensor dirty or going bad, good luck.

Try bleading the brakes, sounds like you have in them. Than the ABS light should go out & you shouldn't have to worry about the fuses.

not a good sign any leaks? if not sounds like abs mod is faulty or wiring faulty check relay that may be cycling all the time

Chevys are bare to blead, especially if it has ABS. Chevy dealers actually use TECH 2 / their computer to blead ABS systems properly. With it, they open the ports in ABS module, which helps the brake fluid flow. Unless of course you have ripped the sensor wire for ABS by accident.
