Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Allow the vehicle to cool down if it has been recently driven.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the electrical connectors from the sensors (use a small flathead screwdriver if necessary).
Inspect the sensors for dirt or damage; clean or replace if necessary.
Reconnect the sensors and ensure they are secured properly.

3. Check Traction Control Module

Locate the traction control module, typically found near the ABS unit.
Inspect the wiring harness for any visible damage or loose connections.
If necessary, replace the module according to the manufacturer's specifications.

4. Examine Brake Fluid Levels

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top off with the recommended brake fluid (typically DOT 4).
Inspect for any leaks in the brake lines or around the master cylinder.

5. Tire and ABS Inspection

Check tire pressure and adjust to the manufacturer's specifications.
Inspect tire tread for uneven wear; replace tires if needed.
Test ABS functionality by performing a controlled brake application to ensure proper operation.
