Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, brake fluid, cleaning brush.
Safety Warnings: Disconnect the vehicle battery before starting work on electrical systems.

2. Scan for Error Codes

Use the OBD-II scanner to retrieve any fault codes related to the ABS system.
Record the codes for reference in diagnosing the specific issue.

3. Inspect the ABS Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the ABS fuse and inspect it for continuity using a multimeter.
Replace the fuse if it is blown, and recheck the system.

4. Check Wheel Speed Sensors

Raise the vehicle and remove the wheels to access the wheel speed sensors.
Inspect each sensor for dirt, damage, or loose connections.
Clean the sensors with a brush if dirty and ensure all connections are secure.

5. Verify Brake Fluid Level

Open the master cylinder reservoir cap and check the brake fluid level.
If the fluid is low, top it off with the manufacturer-recommended brake fluid.
Inspect for any leaks in the brake lines or around the master cylinder.

6. Test Drive and Clear Codes

Once all checks and repairs are complete, reconnect the battery.
Start the vehicle and perform a test drive to ensure the ABS and traction control systems are functioning properly.
Use the OBD-II scanner to clear any error codes and confirm no new codes appear after the test drive.
