Flashing or re-flashing is a term used to describe loading software into a module in a vehicle. Also referred to as programming.
Re-flashing = Roof Repair! Hands-on testing is the only way to determine what the failure is .. There are too many possibilities .. Professional scan test of transfer case module will quickly provide necessary information to locate source failure & needed repair.
