A faulty ABS wheel speed sensor is a common problem that triggers an ABS-disabled warning message on a Tesla. This guide will discuss the Tesla ABS disabled problem and how to replace the ABS wheel speed sensor.

If you are getting these warning messages, start a soft reset. While the vehicle is stopped, press and hold both scroll wheels on the steering wheel.

1. Park vehicle.
2. Go to Controls
3. Go to eBrake
4. Select Power Off

If the problem is the ABS wheel speed sensor, replacing it is very easy and takes about 30 min.
