No, they sent it in mine they told me which electrode went bad in mine and everything. If it's not the EBCM then your problem is the wiring on the wheel hub sensors. I know you checked them but...it's a GP.

So my recommendation is just to get it scanned. Maybe you had two problems. But with the EBCM working properly, you will now get a result when you get it scanned as the ebcm is now functional and can detect which part of the ABS system has the problem.
