Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle's battery and allow it to sit for at least 15 minutes to reset the system.
Tools required: OBD-II scanner, socket set, multimeter, safety glasses, and gloves.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Use a socket set to remove any fasteners securing the sensors.
Inspect the wiring harness for frays or disconnections.
Clean the sensor and surrounding area with brake cleaner before reinstallation.
Reinstall sensors and secure them with the appropriate torque specifications (typically around 10-15 Nm).

3. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; it should be between the minimum and maximum marks.
If low, top off with the manufacturer-recommended brake fluid type (usually DOT 4).
If the fluid is contaminated (dark or cloudy), flush the brake system and replace with fresh fluid.

4. Examine ABS Module

Locate the ABS module, usually near the brake master cylinder.
Check for any visible signs of fluid leaks or corrosion.
If necessary, disconnect the battery, remove the ABS module, and inspect the electrical connectors for damage.
If the module is faulty, replace it with a new one, ensuring proper alignment and torque specifications are followed.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to check the switch's continuity.
If the switch is faulty, replace it with a new switch following the manufacturer’s specifications.
