Error: $0280

[Sonic4262]

Anybody know what this means? It displays this whenever I try to look at the VIN, Operating system, etc. Recently purchased truck from dealership.

$0280. No vehicle detected.
FlashScan or AutoCal could not detect a valid OBD protocol.

Check all cables and connections.
Make sure ignition is turned on to the run position.
Make sure the vehicle is supported by EFILive.

Cheers
