Hi. Having trouble with my Stilo but not quite sure if its all related or bad coincidence. Went out to the car yesterday after having driving it about 2 hours before and I heard a clicking noise from the bonnet. So I opened her up and found it was the red relay on the lower left of the fuse box. I tried swapping them round and it was still that slot clicking. I then opened up the relay and held the switch across which caused the radiator fan to click on. Tried starting the car and I get "ASR Failure" "Car Security Failure" "Loose Connection" warnings. This happens no matter if the relay clicks or the fan is on. Although with the fan on I also get "High Coolant Temp" warnings. Possible water in box? Its at 2002 1.6 16v. Any help would be great. Thanks

Have you checked your battery recently or how old is it?

If you have a multimeter to hand read the battery voltage on a cold morning before driving if possible. Other than that check your D4 multiway connector and make sure its dry as well as the two ECU connections.

Yeh I checked the battery both last night and this morning. Both readings were 12.56v.
Ive taken out the Fuse Box and checked all the contacts and plugs and they seem okay. Im thinking maybe the ECU or fused box innerds might have gotten wet?

Cheers Ill give that ago. I checked the fuse box connections but didnt check that one. Is it in the gap below the fused box? Theres a fair few in that area.

Ive checked out that plug and it seems dry enough. The local garage want to check the compression because it doesnt fire but personally I think this is a waste of time as it wont fire with car security failure?

Have you checked the ECU connections? That would be the one last thing I would do.

They are simple enough to move and replace. And dont worry about your ECU getting wet. The backs are sealed to prevent anything getting in, and on the inside they are set in like a rubbery silicone stuff to steop anything going wrong.

My friend down at garage used to work for Fiat and hes now suggesting it could be the Crank sensor knocking everything out? All the connections are bone dry.
