Why does my ABS light on my 1999 Mazda B3000 pickup stay on all the time?

The ABS light on your 1999 Mazda B3000 pickup may stay on due to a malfunction in the anti-lock braking system, which could be caused by a faulty ABS sensor, a damaged wheel speed sensor, or issues with the ABS control module. It could also indicate low brake fluid levels or a problem with the brake system itself. To diagnose the issue accurately, it’s best to use an OBD-II scanner to retrieve any error codes, or consult a mechanic for a thorough inspection. Ignoring the light can lead to reduced braking performance, so it's advisable to address it promptly.
