ABS is engaged all the time with no ABS light on. Rear brakes were recently done with spring kit and new adjusters. How do I reset ABS system?

Sounds like you have a bad speed sensor that is telling the ABS unit that one of the tires is locked up. You will need a scan tool to read the actual speeds from the sensors and see which sensor(s) are not reading correctly. It only takes a minor speed difference from a sensor to trigger this behavior.

Sounds possible.
Rt rear adjuster was floating around in the drum.
Some teeth are damaged on trigger.

That would do it. The sensor is reading the damaged teeth on the tone ring differently and kicking on the ABS. I have seen this when a tone ring was damaged, even worse when one cracks. Thing that stinks is having to pull those hubs.

Well you can pull the fuse for the ABS, it will stop working but the light will stay on all the time. The base brakes will still work fine, you just lose the ABS.

If it has traction control it will stop working as well as the ABS.

The fuses should be in the battery junction box and tagged as ABS
