Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, brake fluid.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove the sensor mounting bolt using the socket set.
Disconnect the electrical connector from the sensor.
Inspect the sensor for dirt, damage, or corrosion. Clean or replace as necessary.
Reconnect and secure the sensor in its position.

3. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; it should be between the minimum and maximum marks.
If the fluid is low, top it up with the recommended brake fluid type (usually DOT 4 for VW).
Reconnect the reservoir cap securely.

4. Inspect ABS Module Wiring

Locate the ABS module, usually found near the brake master cylinder.
Visually inspect the wiring and connectors for any damage or corrosion.
Use a multimeter to check for continuity in the wiring.
Repair or replace any faulty wiring as needed.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the traction control light remains illuminated.
Take the vehicle for a test drive to verify that the traction control system is functioning properly.
