Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris around the sensors using a soft cloth.
Check the sensor wiring for any frays or damage; repair or replace as necessary.

3. Check ABS Module Connections

Locate the ABS module, typically found near the brake master cylinder.
Inspect the wiring harness for disconnections or corrosion.
Clean the connectors with electrical contact cleaner and reattach securely.

4. Brake Fluid Inspection

Check the brake fluid reservoir for the proper level; top off with the recommended fluid type (DOT 3 or DOT 4).
If the fluid is contaminated, perform a brake fluid flush and replace with new fluid.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to test the switch for continuity. Replace if faulty.
