Good morning,
I have a 10/2013 1.3 Mjet 500L (engine 199B4000) in the workshop.
It had broken down because of a flat battery, of course after the usual checks, battery OK (tested), it immediately jumped that the alternator does not charge.
Obviously the easiest thing was to replace the alternator with a remanufactured one, but nothing. Following this, I saw that there are some of these cars on which there is a software update, specifically concerning the alternator charge, at which point I called a friend at Fiat and brought it in. There are no updates on this car, and after some checking by them too, he advised me to replace the alternator again. To do things right I got a new one (Delphi) and replaced it, but nothing.
I heard another friend from another fiat workshop and he tells me that it cannot be anything other than the alternator.
But it won't be him anymore... In the injection control unit diagnosis it keeps giving me error P068A Battery disconnection, I also tried replacing the battery sensor, but nothing.
To make sure I didn't miss anything, since it is obviously a smart alternator controlled by Lin line, I also tried coding an injection control unit (from recovery), but still back to square one.
Car chassis ZFA19900005020258
Number plate ES709PR
I welcome advice!
