Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Clean the sensors and surrounding areas to remove any debris or dirt.
Check the sensor connectors for secure attachment and no corrosion.
Replace any damaged sensors with OEM parts.

3. Check ABS Module

Remove any panels necessary to access the ABS module.
Inspect the module for any visible damage or loose connections.
Use a multimeter to test for proper voltage and ground at the ABS wiring harness.
If the module is faulty, replace it following manufacturer specifications.

4. Brake Fluid Level Check

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top it off with the manufacturer-recommended brake fluid type.
Inspect for any leaks in the brake system that may need attention.

5. Reconnect Battery and Test

Reconnect the battery terminals securely.
Clear any error codes using the OBD-II scanner.
Test drive the vehicle under various conditions to confirm the traction control system is functioning correctly.
