Didnt know where to put this so might be wrong forum part but here goes.
A friend of mine have a Fiat Barchetta and something has gone wrong with the imobilizer. As far as i can tell from what the workshop figured out is that its the code box that's at fault. Now i have that striped out on my desk and not sure what i might be looking for. My first gut feeling was looking for a bad cap. Sure enough there is a lytic in there but im unsure that would actually be the problem.
The lytic is an Frolyt EKS 220uF 35V cap

In circuit the values looks reasonable (0,26 ESR 200uF). From what the workshop said it doesnt communicate as it should with the ECU. But it seems to work somewhat cause the warning light for the imobililizer does go out as it should, you cant start the car however.
Any guesses what might be a possible suspect in this case?
Also, was looking at replacements for that cap to maybe try it, nothing to loose since a cap is cheap, would it be a problem going up in ripple, would that effect the circuit at all?
