Hi all! I have a manual 2015 Fiat 500, 1957 edition, and for a while now all three lights for abs, esc, and hill assist have been on and not working. I believe it's a bad sensor but I'm not sure where it is or how to check that. Has anyone else ever had this happen?

How old is the battery? Have it "load" tested. Clean connection and grounds UNDER the battery.

The battery is pretty new. I just got it last September. I think it's a sensor that's gone bad? The lights used to come on then go off, and now they're just on all the time .

Darn then you need to check the hatchback wiring harness that sometimes causes havoc , on my 2013 sport it was the brake switch and hatchback harness wires were all chewed up
