I have a 2012 S60 Volvo. The previous owner had a front Parking Assistance System (PAS) installed. Company is Haodi Australia - it is impossible to find anything on the internet. The orginal installer of the system is 3 1/2 hours away. This past weekend I was driving, it started raining and sometimes when it rains hard the PAS will beep. I flipped the switch to turn it off. On Sunday I attempted to turn the PAS back on - helpful when pulling into garage etc... it beeps when too close to objects. Only have for front. The system was not working. I am thinking it could be a loose wire or the fuse, but not sure what fuse it would be? Any ideas? Thoughts? Thanks
