Technical Fiat 500 , 100HP 16V 2011

[Raflyramadhan]

Hi guys, I'm from Indonesia I have a Fiat 500 1.4 (2011) without engine start/stop button, I hope you guys can help me solve my endless problems.



I have replaced the ECU and have cloned the old ECU to the new ECU



The problem with the car now is: the engine starts for about 1 minute after it stops, always repeats so it won't stay still and the indicator shows Fuel Cut Off Not Available also sometimes "Has Power Steering Check" and a triangle (!) appears.



Things I've tried:

1. Replace battery with 45Ah & 420 CCA

2. Check all earth wires & clean them

3. Check all fuses



And after I scanned it using Launch X431, the error code was only displayed from the ABS module:

1. U1700-92 :

2.U1700-87: BCM Lost Message (Saved)

I'm already at a dead end, don't know how to fix it, so I really hope someone can give me an answer to this problem. Thank You



PS : I have attached several photos & videos below

I am no expert but feel strongly if its going haywire it is likley a chafed wire somewhere causing short circuits. The more things look impossible the more ;ikely it seems to be something like this. Anywhere the wires bend is suspect so tailgate hinge and door hinges would be the first thing I would check and rule out. I have the MES software from Gendan.co.uk and find it is much netter than my standard non Fiat diagnostic tool. Im sure someone else will be along with some better pointers soon.
