The ABS light indicates issues with your anti-lock braking system. Common causes include low brake fluid, faulty wheel speed sensors, damaged ABS rings, module failure, or electrical problems. While your regular brakes typically work when the light is on, the anti-lock function is disabled, increasing skid risk during emergency braking.

Look for a slow engine crank, dim lights, or electrical problems as signs your car battery might be failing. Regular checks with a battery tester can help prevent breakdowns.

Use your car scanner to check the catalytic converter! Plug it in, read codes like P0420, and examine live oxygen sensor data for clues.
