Rear diff inoperable message
Just tuned the car using a handheld and it says rear diff lock inoperable but once the tune loads and I restart the car the message disappears and doesn’t return. It’s not the tune just don’t know if it’s normal when using a handheld to download tune to vehicle.

i dont think its the tune. I got that message today too briefly and then it went away and didnt come back. I thought the -40 weather was tripping the car out but im going to a dealer next week anyway so ill point it out and they can check whatever they have to.
