Hi, can't really find any definitive threads so hopefully someone can help. My rear park sensors are faulty, had them run diagnostic and it came back all 4 were not working, garage said it could be the ECU for the sensors, but all the front sensors work fine. Question is, does the front and rear have separate control modules and where are they located, also is this likely to be the issue. Tia peeps.
