Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake cleaner, safety glasses, gloves.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect Wheel Speed Sensors

Locate each wheel speed sensor on the front and rear wheels.
Remove the sensor mounting bolts using a socket set.
Carefully pull the sensor out and inspect the wiring harness for any damage.
Clean the sensor tip with brake cleaner to remove any debris.
Reinstall the sensor, ensuring it is properly seated and secured.

3. Test ABS Module

Reconnect the battery and use the OBD-II scanner to check for ABS module codes.
If codes persist, locate the ABS control module and inspect the wiring harness for any loose connections or damage.
If necessary, replace the ABS control module following manufacturer specifications.

4. Check Brake Fluid

Open the brake fluid reservoir and check the fluid level.
If low, add the recommended brake fluid type (usually DOT 4 for BMW).
Inspect the fluid for contamination; if contaminated, perform a brake fluid flush.

5. Clear Error Codes

After completing repairs, use the OBD-II scanner to clear any error codes related to the ABS system.
Ensure no codes reappear and that the ABS light is off.
