Bulletin 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.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
