Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Address Diagnostic Trouble Codes (DTCs)

Sub-steps:
1. Use the OBD-II scanner to retrieve and note any DTCs related to the traction control system.
2. Research the codes in the service manual for specific issues.

3. Inspect and Replace Wheel Speed Sensors

Sub-steps:
1. Lift the vehicle and remove the front wheels for access.
2. Locate the wheel speed sensors on each wheel hub.
3. Disconnect the electrical connectors from the wheel speed sensors.
4. Remove the mounting bolts and take out the sensors.
5. Install new sensors and secure them with bolts.
6. Reconnect the electrical connectors.

4. Verify ABS Module and Wiring

Sub-steps:
1. Locate the ABS module and inspect for signs of corrosion or damage.
2. Check wiring harness for frayed wires or loose connections.
3. If necessary, replace damaged wiring or the ABS module.

5. Check Brake Fluid and Replace if Necessary

Sub-steps:
1. Locate the brake fluid reservoir and inspect the fluid level.
2. If low, top up with the manufacturer-recommended brake fluid.
3. If the fluid is contaminated, flush the brake system and refill.

6. Inspect and Replace Fuses

Sub-steps:
1. Locate the fuse box under the dashboard or hood.
2. Identify the fuse for the traction control system and inspect its condition.
3. Replace the fuse if it is blown, ensuring the new fuse matches the appropriate amperage.
