The method includes a master ECU storing a shared key and an expiration date of the shared key. When the master ECU receives an update message, verifying update authority information indicating authority of the external tool, and determining whether or not a transmission of the update message is within a range of an authority of the external tool. The method also includes acquiring external point-in-time information, determining whether or not the external point-in-time information is before the expiration date, and transmitting an alert message prompting an update of the shared key. The ECUs are prioritized according to a designated level of authority, including chassis-related functions, body-related functions, safety/comfort functions, and telematics/infotainment functions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Update management method, update management system, and non-transitory recording medium","description":"An update management method is used in an onboard network system having a plurality of electronic control units (ECUs) that performs communication via a network and connects to an external tool.
