Hi ineedlove1956. Welcome to the forum. I'm not familiar with your specific car model, but I can share some basic information about the anti-lock brake system.

Don't worry about the traction control system. It is disabled now only because the ABS system is disabled. Traction control makes use of the ABS feature so when the ABS doesn't work, the traction control can't. The tires will not suddenly start to cause a problem. Mismatched tire sizes will cause a problem, but normal wear will not cause a sufficient size difference to be noticed. The same is true for a tire that is slightly low on air pressure. If you just installed one or two tires that are different in size compared to the others, that COULD cause a problem.

The ABS warning light should turn on for a few seconds while the system performs a self-test, then it will go off. In general, if the light goes off, then turns right back on, the problem is related to a pressure sensor or a wheel speed sensor electrical problem. If the light stays on steady as soon as the ignition switch is turned on, and it never blinks off for a fraction of a second, suspect a blown fuse. If the light does not turn on until after the car has been moving a substantial distance, suspect cracked tone rings by the wheel speed sensors. Metal filings stuck to the end of the magnetic sensors will cause this symptom too but this is not as common.

Electrical problems can include a blown fuse. There will always be at least two fused power circuits for the ABS system. One is the backup circuit to run the warning light if the other circuit goes dead.

Was this
