Solution

1. Preparation

Gather required tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Ensure the vehicle is on a flat surface and securely supported.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Clean any dirt or debris from the sensor area.
Check the wiring for signs of wear or damage; repair or replace as necessary.
Reconnect any loose connections.

3. Check ABS Control Module

Locate the ABS control module (usually under the hood).
Inspect the module for any visible damage or corrosion.
Ensure all electrical connectors are securely attached.
If necessary, perform a continuity test on the wiring harness using a multimeter.

4. Brake Fluid Inspection

Open the brake fluid reservoir and check the fluid level.
If low, top off with the manufacturer-recommended brake fluid.
Inspect for any leaks in the brake line or around the brake calipers.

5. Verify Traction Control Switch

Locate the traction control switch in the vehicle's cabin.
Test the switch by pressing it to ensure it engages and disengages.
If faulty, replace the switch with an OEM part.
