Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect and Replace Wheel Speed Sensors

Sub-steps:
1. Raise the vehicle and secure it on jack stands.
2. Remove the wheel to access the wheel speed sensor.
3. Disconnect the electrical connector from the wheel speed sensor.
4. Remove the mounting bolt(s) securing the sensor and pull it out.
5. Install the new wheel speed sensor by reversing the removal steps.
6. Reconnect the electrical connector and ensure it is secure.

3. Replace ABS Fuse

Sub-steps:
1. Locate the fuse box under the dashboard or engine compartment.
2. Identify the ABS fuse using the fuse diagram.
3. Remove the fuse using a fuse puller or pliers.
4. Insert a new fuse of the same amperage rating.
5. Recheck the fuse box cover for proper closure.

4. Test and Reprogram ABS Module (if necessary)

Sub-steps:
1. Reconnect the negative terminal of the battery.
