Hello, just got 2016 gtc4lusso, 20k miles, i have check engine error, connected autel and it shows this: Image Unavailable, Please Login
Well we cant really help with that. You need to go to the dealer. It might be a faulty battery leading to an ECU not booting properly. It could be a bad ECU, it could be a damaged wiring loom... Did you do a PPI?
Try and preform a proxy align with your autel. It basically tells all ecu's to say "hello" to each other. Do you know what caused it? What did you do that caused the light. Need more details
This message is a sync problem between nav unit and well anything. Can be solved by syncing up all ECUs. This message seems to be more frequent after servicing a Ferrari.
