Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and ensure the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Scan for Error Codes

Use an OBD-II scanner to read fault codes.
Note any codes present and clear them from the system.
Reconnect the battery.

3. Inspect Wheel Speed Sensors

Remove the wheel on the affected axle using a socket set.
Locate the wheel speed sensor at the rear of the brake rotor.
Clean any dirt or debris from the sensor and surrounding area.
Inspect the wiring harness for cuts or corrosion.
Reinstall the wheel.

4. Check ABS Module

If any fault codes related to the ABS system are present, inspect the ABS module connections.
Ensure all connectors are secure and free from moisture or corrosion.
If necessary, replace the ABS module.

5. Examine Fuses

Locate the fuse box (check the owner’s manual for exact location).
Identify the fuses related to the traction control system.
Replace any blown fuses with the same amperage rating.

6. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Ensure the fluid level is between the minimum and maximum marks.
If low, top off with the recommended brake fluid type (usually DOT 3 or DOT 4).
Close the reservoir cap securely.

7. Test Traction Control Switch

Verify the functionality of the traction control switch on the dashboard.
If the switch is defective, replace it by removing the trim panel to access the switch.
