Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical issues.

2. Scan for Error Codes

Use an OBD-II scanner to retrieve any fault codes related to the traction control system.
Document any codes for reference.

3. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors near each wheel hub.
Remove any dirt or debris around the sensors and clean them with an appropriate sensor cleaner.
Ensure the wiring harness is intact and securely connected.

4. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if it is low, top it off with the manufacturer's recommended brake fluid.
Check for any leaks around brake lines or connections.

5. Inspect ABS Module and Wiring

Locate the ABS module, typically found near the brake master cylinder.
Examine the module and wiring for any visible damage or loose connections.
Reconnect any loose connectors and secure the wiring harness.

6. Tire Inspection

Check each tire for proper inflation and tread wear.
Replace any tires that are excessively worn or damaged.

7. Reconnect Battery and Test

Reconnect the battery terminals.
Start the vehicle and check if the traction control light remains illuminated.
Perform a test drive to ensure the traction control system is functioning correctly.
