The TCU software improves the thermal management system and eliminates erroneously stored faults. The TMU software adds WiFi connection capability to the vehicle.
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
