Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a level surface and secure with wheel chocks.

2. Inspect and Repair Wheel Speed Sensors

Tools Required: Multimeter, socket set, torque wrench
Locate the wheel speed sensors at each wheel hub.
Unplug the sensor's electrical connector.
Use a multimeter to measure the sensor's resistance; compare with manufacturer specifications.
If out of spec, remove the sensor by removing the mounting bolts.
Clean the sensor area if dirty, and replace with a new sensor if faulty.
Reinstall and torque to manufacturer's specifications.

3. Check and Replace ABS Fuse

Tools Required: Fuse puller or pliers
