Hello family
I had this situation, 2012 Fiat 500 Gucci 1.4 NA 108.000 miles, after a little use during the day I received this codes at the same time, the car enter in limp mode, if I turned off and on start driving good with the check engine light on until again go into limp mode. even after cleaning the codes (I have an autel scanner) they comeback together. even the rear hatch light on the dashboard is blinking, hillstart is deactivated. esc deactivated.

Have you checked the hatch wiring for problems?!

Checked every wire, I just followed the instructions on the workshop book and meassure the resistance on the injector, was over the limit and I just replaced it, its annoying but if you have a ratchering wrench its easy.

The hatch wiring at the rear …. Rubber grommet from car to rear hatch! Known issue with wires breaking and shorting out causing all kinds of issues
