1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Faulty Wheel Speed Sensors

Tools Required: Socket set, multimeter, torque wrench
Remove the wheel on the affected side to access the wheel speed sensor.
Disconnect the electrical connector from the wheel speed sensor.
Use a multimeter to test the sensor’s resistance; replace it if the readings are outside the recommended specification.
Install the new wheel speed sensor and torque the mounting bolt to the manufacturer’s specifications.
Reconnect the electrical connector.

3. Check and Replace ABS Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box under the dashboard or engine compartment.
Identify the ABS fuse using the diagram on the fuse box cover.
Remove the fuse and inspect it for continuity; replace it if blown.

4. Inspect and Repair ABS Module

Tools Required: Socket set, multimeter
Locate the ABS module, usually found near the master cylinder.
Visually inspect for corrosion or damage.
Use a multimeter to test the power supply and ground connections to the module.
If faulty, remove the ABS module and replace it with a new one, ensuring all connections are secure.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals.
Use the OBD-II scanner to clear any stored ABS codes.
Start the vehicle and check if the ABS light turns off.
