sorry mate at this moment in time i can't access the info you need ,maybe able to get it monday .is the door switch ok ??? as if the switch is faulty the vic wont see the door open and hence you won't get the audible warning ..if you can't wait till monday , check all fuses and relays ,and there is an electrical plug at the handbrake ,check the feed ,also is the (p) light going out on the DIP? if not then the handbrake switch may be at fault .you find that to the right of the handbrake buried ,following the air pipe should lead you to it ...what year of truck is it ,as things change and DAF 85 is pretty vague as it covers every model since it's launch ..as there is the euro2 85cf ,then cf 85 euro3 , cf euro 4 ,cf euro 5 ...and the 85cf is correct lol
