After decrypt my check engine and airbag light is on.

Question

All wires are hooked up right the remote start and oem alarm works great. I have done different options multiple times to no avail. Everything else works good just check engine and airbag lights are on. I have the fortin evo all. Car is a 2014 Fiat 500L

Answer 1

Is the check engine light on when you start the car normally with the key?

 

Do the codes go away if you unplug the can bus connector on the evo?

Hi Derek, thank you for the help, the codes are there if I remote start it or start it regularly. Also when I remote start it and unlock my door it says to check my transmission then the light goes away for that one but the check engine and airbag one stays. I also tried disconnecting everything from the bus connector on the evo and the check engine light went away but the airbag light stayed on. When I reconnected it, the check engine light went back on. I checked all wiring, connections, checked for any loose wiring, etc. I am stumped..

Did you perform the key release connection?

Hey Derek I know it’s an old thread but I have kind of same issue,

Evo-One

Remote started or key started, the car would randomly throw a Check Engine and Verify transmission message on the dash and when it does you can’t drive the car, putting in gear do nothing at all, tried with factory alarm active, with factory alarm not active, another Evo-One, but the problem keeps coming back, unplugged the Evo during summer and the problem went away, now for winter I have plugged it back and sure enough the problem came back.

Do you have any input on that ? I did NOT cut the key release wire

What is the actual code being set? Ill take a read into it when I can.
