Summary
TT: Some 2020 model year Japan built Corolla vehicles may exhibit a condition where the battery may become depleted during shipping. It has been discovered that when the D/C cut fuse is not installed voltage may continue to flow to an ECU while the vehicle is powered off causing a parasitic draw depleting battery state of charge.
