Hi guys, I’m from Indonesia I have Fiat 500 1.4 (2014) without engine start/ stop button, I hope you guys can help me solve my endless problem.

2 years ago, I’ve changed the BCM & Automatic Transmission Shift Knob at an authorized dealer, but the problem is at the moment there’s no authorized dealer in Indonesia at all. So there isn’t a single workshop that can do online coding/ programming.

The problem with the car now are : sometimes the engine can’t be start (cranking only) and the indicator shown Fuel Cut Off Unavailable also sometimes “Have Power Steering Check” and the steering wheel becomes heavy. But sometimes the car can be perfectly fine, no indicator lights, everything’s work normally like there’s nothing happened.

Things that I’ve tried :
1. Replacing the battery with 45Ah & 420 CCA
2. Replacing original Fiat brake switch
3. Checking all of the earth cable & clean it up
4 Checking all of the fuses

And after I’ve scanned it using Launch CRP 123, the error code only showned from ABS modul :
1. U0001-88 : CAN C Bus Off (Stored)
2. U1702-87 : ABS/EPS Missing Message (Stored)
3. U1700-87 : BCM Missing Message (Stored)
4. U1715-87 : Yaw Rate Sensor Missing Message (Stored)
5. *This fall sometimes did not show, C1212-55 : Variant coding Not Configured (Stored)

I’ve meet the dead end, had no clue how to fix this, so I really wish there’s someone that can give me an answer for this problem. Thank you

PS : I’ve attached some photos & videos below
