Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to ensure safety.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Reset Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Navigate to the ABS module and clear any existing error codes.
Reconnect the negative battery terminal and restart the vehicle.

3. Inspect and Clean Wheel Speed Sensors

Remove the wheels to access the wheel speed sensors.
Detach the sensors from their mounts.
Clean the sensor tips with a soft cloth and brake cleaner to remove any dirt or debris.
Reinstall the sensors ensuring they are properly seated and secured.

4. Check ABS Module and Pump

Locate the ABS module, usually found near the master cylinder.
Inspect the module for any signs of leaks or physical damage.
Using a multimeter, check the voltage and ground at the ABS module connector.
If necessary, follow the manufacturer’s specifications for testing the ABS pump operation.

5. Reassemble and Test

Reinstall the wheels and ensure all bolts are torqued to the manufacturer's specifications.
Lower the vehicle and perform a test drive to check if the ABS light remains off and the system functions correctly.
