Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel assembly.
Remove any debris or dirt around the sensors using a clean cloth.
Check the wiring harness for any signs of wear or damage.

3. Replace Damaged Sensors (if necessary)

Remove the wheel associated with the speed sensor that is faulty.
Unbolt the damaged wheel speed sensor from its mount.
Install the new wheel speed sensor and torque the bolts to the manufacturer's specifications.

4. Check and Refill Brake Fluid

Open the brake fluid reservoir under the hood.
Check the fluid level and add the correct type of brake fluid as specified in the owner’s manual.

5. Inspect and Repair ABS Module

Locate the ABS module and check for any corrosion or loose connections.
Reconnect any loose connectors securely.
If the module is damaged, replace it following manufacturer instructions.
