Bulletin Summary
TSB: Some 2023 model year Crown vehicles may exhibit a delay and/or reduction in output of warm air from the HVAC system while the vehicle engine is at normal operating temperatures (over 170°F). This condition usually occurs immediately after a hot restart, while the vehicle is in Ready ON, but before the internal combustion engine starts. The Engine Control Module (ECM) (SAE term: Powertrain Control Module/PCM) logic has been modified to reduce the possibility of this condition.
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.
