What is B0363?

DTC B0363 is a diagnostic trouble code that indicates a problem with the seat heater control circuit, particularly affecting the driver's seat. This code is commonly encountered in various Ford models, including the Ford F-150 from 2015 to 2018, where it may trigger due to an open circuit or an issue with the seat heater module. When this code appears, it suggests that the onboard diagnostic system has detected a malfunction in the seat heater's wiring or components. In practical terms, this means that the heated seats may not function as intended, leading to discomfort during colder months. If left unresolved, the issue could potentially lead to further electrical problems or even affect other systems that share the same circuit. For vehicle owners, understanding this code is crucial, especially if you rely on heated seats for comfort. Timely diagnosis and repair can prevent additional complications and ensure your vehicle remains safe and comfortable to drive.
