Solution

1. Preparation

Gather necessary tools and equipment.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Connect OBD-II Scanner

Locate the OBD-II port under the dashboard (usually near the driver's side).
Plug in the OBD-II scanner and turn on the vehicle to the accessory position.

3. Access ABS Module

Navigate through the scanner's menu to select the ABS module.
Follow the prompts to read DTCs stored in the ABS system.

4. Analyze DTCs

Note down any error codes displayed and reference them against the BMW service manual for specific meaning.
Check if any codes indicate a faulty ABS sensor or module.

5. Inspect ABS System

If any codes suggest wiring issues, visually inspect the wiring harness connected to the ABS module.
Look for frayed wires, corrosion on connectors, or any signs of physical damage.

6. Clear Codes (if applicable)

If repairs or inspections were performed, clear the DTCs from the ABS module using the OBD-II scanner.
Turn off the ignition and disconnect the scanner.
