Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Wheel Speed Sensors

Locate the wheel speed sensors for each wheel.
Use a socket set to remove any fasteners securing the sensors.
Disconnect the sensor connectors and remove the sensors from their mounts.
Inspect the sensors for corrosion or damage; replace if needed.
Install new sensors by reversing the removal steps, ensuring the connectors are secure.

3. Check and Refill Brake Fluid

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if low, top off using the manufacturer-recommended brake fluid.
Check for leaks in the brake lines and connections.

4. Inspect Traction Control Module

Access the traction control module, typically located near the ABS module.
Check all electrical connectors for corrosion or damage.
If necessary, reprogram the module using a compatible diagnostic tool.

5. Tire Inspection

Examine all tires for uneven wear or flat spots.
Ensure all tires have adequate tread depth; replace if necessary.
Rotate tires as needed to ensure even wear.
