FRONT PDC not working QUIET AND SILENT

was wondering if any of you can give a suggestion how to proceed from here.
Car : 05 E53 M54 162500 miles no ses.Well maintained.Stock
Symptom: Wife puts car in reverse- gets long beep then beeping stops and PDC button blinking.PDC inoperative
WHAt I did so far: Checked #6 fuse(E53) intact ,swapped with known good fuse.Same long beep on reverse .Still not working,Checked rear sensors with my stethoscope- ALL REAR Sensors have TICKING sound, went to check the front -ALL ARE QUIET and SILENT
Question: could ALL 4 FRONT sensors be bad OR could it be a wiring or software issue?
Any suggestions (general) where to go from here to diagnose the issue?
Thank you in advance .Will post question on Xoutpost too ....
