PDC acting up..

Hey There,



My PDC system is just driving me insane. It all started with when the car is in reverse there would be no sound at all....



What i did:



Replaced the Drum.



What was the result:



Now i had sound, unfortunately it was the 5 continues seconds as soon as it put the car back in reverse



What i did:



Replaced the broken sensorS and one of the wires going to the thrids sensor was cut so fix it as well.



What was the result:



We are back at the start again, no sound coming out at all, all sensors are properly working ( tickering sound when i put my ear to them) and drum is working as well, and i have no idea what else could it possibly be.:banghead::banghead:



I have installed a Dynavin and i was wondering if there are extra wires that should feed to it, from the old Control unit. Or if there are any other ways to troubleshoot what could possible be wrong. ( I have also read the codes but i have none showing up)



Any ideas on how to troubleshoot the remaining parts? The CU is 150£ and i don't want to go buy one and having it not work again.



Thanks for your help!:thumbsup:
