Re: I Need help with a Fault!! stilo 1.2 16v

Hi guys, i have exactly the same symptoms as described by irishstilo99,
I allready check the fusebox engine bay and inside the car, all the earth connector, measure it with multimeter, etc etc. I even take apart the dashboart to the bear metal just to see if there is any wiring that is shorting.
This problem appeared from nowere in january, and until today, after a few trys the car started but yesterday give up totally.
If there is any ideea from u guys please share that info,
Last try i will buy an ecu kit with the bcm unit , to dont hassle arround with reprograming ecu.

Irish found a faulty coil was causing the problems. Have you checked yours?

When you say you had the same fault, do you mean a loud ticking and then the dashboard died, or was it just the engine that died? You might have a cam-sensor fault.

Re: I Need help with a Fault!! stilo 1.2 16v

Hi Ralf S.
Late reply, as i get busy with work. Yes i checked everything, from spark to coils, earth conectors, fuse boxes, everything, i checked for short circuit, all the tips from forum that i could find.
I ordered a full ecu kit with the bcm , keys and locks.
Strong feeling that on the end my ecu it is dead.
The car simply stoped working, i get at work, and later when was to go home i coukdn't start it anymore.
I will let you guys a note after i change the ecu if the car run or not.
Btw, by changing the ecu and bcm body i need to make proxy alignment right?
Thank you.

Yes, the BCM can talk to the ECU and the new key but it will have to be aligned with the other modules (dashboard, central locking, mirrors etc.) but the car should still work, even if there's a load of errors flashed up when you switch it on.

As fas as the key and locks are concerned, you should be able to replace the chip in your key with the chip from the new key, which will save yoy a job of changing all the locks. Or you can fit your key blade into the new key, if the other key looks in better condition.

And, as long as the BCM picks up the signal from the key, then the immobilisor won't become moody.. so before you change *everything*, just tape the new key next to the ignition barrel, so it can be detected and so the car will start. If you get the car running then at least you will know it's all going to work before you change too many things and then (if it doesn't work) won't know what it could be.

Hi again Ralf S. ,

So i changed the ECU, the BCM and the key barrel, car works in perfect condition ( thanx God) , i missed my Stilo. I am driving a Nissan Juke from 2018 as replacement until i finish some tests on the Stilo and i can say that i have more pleasure driving my "underpowered " 1.2 petrol engine Stilo , than the Juke. Stil a fun car to drive .
Unfortunatly after few test and scans with MultiEcu , i still have that U1602 or U1601 error with Can connection problem.
The car have no.warning lights, starts from first turn of the key and works perfect.
I am still worried about what the heck could be wrong there, as were checked everything, as i previosly mentioned.
Any tips?
Thank you!

I'm not 100% sure what those codes are but U1601 is usually a key reading issue - either it can't read the key, the key signal is incomplete, or it picked up a signal from another key.

Do you have another key (e.g. the original one) next to the ignition key you are using?

The other thing to check is the connections to the key reader ring around the ignition barrel. If you had yours apart it could be damaged or not properly connected.
