Hi Dan. I had an ABS light and the problem was the module so I changed the module but it didn't fix the problem. Now I get the code u1000 saying that there is a communication error with the module and computer. There is also a sound coming from the wheels. What can I do to solve this problem?

There fault code U1000 seems to be a communication problem, could be due to several factors such as wrong replacement parts with coding issues or programming compatibility, or undiscovered (or not reported) damage but to be sure lets do a CAN scan which is the future of automotive repair you can get a CAN scanner from Amazon for about $50.00 here is a video to show you how.
