Solution

1. Preparation

Gather tools and equipment: OBD-II scanner, multimeter, socket set, and torque wrench.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Address Fault Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and document any stored fault codes.
Clear the codes and see if they return after a short test drive.

3. Inspect and Replace Faulty Components

Wheel Speed Sensors:
- Locate the wheel speed sensors at each wheel.
- Disconnect the sensor wiring harness and inspect for damage or corrosion.
- If damaged, replace the sensor with a new one. Torque the mounting bolts to manufacturer specifications.
Brake Fluid Level:
- Open the hood and check the brake fluid reservoir.
- If low, top off with the recommended brake fluid type (typically DOT 3 or DOT 4).
- Inspect for any visible leaks in brake lines or connections and repair as necessary.
Brake Pedal Switch:
- Locate the brake pedal switch near the pedal assembly.
- Use a multimeter to test for continuity when the pedal is depressed.
- If faulty, remove the old switch and install a new one, ensuring it is properly aligned and secured.

4. Inspect ABS Control Module

Check the ABS control module's connections for corrosion or loose wiring.
If necessary, replace the ABS control module according to the manufacturer’s instructions, following all safety protocols.

5. Reassemble and Test

Reconnect all components and ensure no tools are left in the engine compartment.
Start the vehicle and check for any warning lights.
Perform a test drive to ensure ABS and traction control systems are functioning correctly.
