Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Remove the wheel from the affected axle.
Locate the wheel speed sensor on each wheel hub.
Carefully disconnect the sensor's electrical connector.
Clean the sensor and the mounting area using a suitable solvent.
Reconnect the sensor and ensure it is securely mounted.

3. Check ABS Module and Wiring

Locate the ABS module, usually found near the brake master cylinder.
Inspect the wiring harness for any signs of damage or corrosion.
If necessary, use a multimeter to test the continuity of the wiring.
Repair or replace any damaged wiring or connectors.

4. Brake Fluid Level Check

Open the brake fluid reservoir cap.
Ensure the fluid level is between the minimum and maximum marks.
If low, top up with the recommended brake fluid (DOT 4 for BMW vehicles).
Replace the cap securely after checking.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the vehicle and check if the traction control warning light is still illuminated.
Test drive the vehicle to ensure traction control is functioning properly.
