Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety.
Allow the engine to cool before working on electrical systems.

2. Inspect and Repair Wheel Speed Sensors

Locate each wheel speed sensor at the wheel hub assembly.
Remove the sensor's electrical connector.
Clean the sensor area and connector with electrical contact cleaner.
Inspect for any damage; replace if necessary (part number may vary by model).
Reconnect the sensor and repeat for all four wheels.

3. Check ABS Control Module

Locate the ABS control module, typically found near the brake master cylinder.
Inspect the wiring harness for any signs of wear or damage.
If necessary, disconnect and clean the electrical connectors.
Test the module using a multimeter for proper voltage and continuity; replace if faulty.

4. Verify Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, fill with manufacturer-recommended brake fluid.
Inspect for any signs of leaks in brake lines or around the master cylinder.

5. Replace Traction Control Switch (if necessary)
