The electronic controller (20A) recognizes connection of the first external tool (10A) by a comparison circuit (212A) for monitoring a received voltage and a write-mode determination circuit (218A), initializes a microprocessor (200), and receives and stores an total control program (TCPRG) in a program memory (204A) based on a content of a boot program memory (201). During an operation of the electronic controller (20A), the external tool (10A) is removed and the high voltage (Vaa) is not applied to the communication line (LANH). Therefore, the electronic control apparatus is not erroneously placed in the write mode."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electronic controller to be connected to program tool","description":"A first external tool (10A) serially connected to an electronic controller (20A) through a pair of communication lines (LANH, LANN) applies a high voltage (Vaa) higher than a normal control voltage (V","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9779045","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
