These diagnostic trouble codes (DTCs) help identify problems within the vehicle\u2019s data bus or CAN system, which can affect how electronic modules share information. The U code family is further divided into specific subcategories that indicate the nature of the fault:<\/p>\r\n\r\n<ul>\r\n \t<li><strong>U00XX<\/strong> - Network Electrical<\/li>\r\n \t<li><strong>U01XX<\/strong> - Network Communication<\/li>\r\n \t<li><strong>U02XX<\/strong> - Network Communication<\/li>\r\n \t<li><strong>U03XX<\/strong> - Network Software<\/li>\r\n \t<li><strong>U04XX<\/strong> - Network Data<\/li>\r\n \t<li><strong>U05XX<\/strong> - Network Data<\/li>\r\n \t<li><strong>U06XX<\/strong> - U0FXX \u2013 ISO\/SAE Reserved<\/li>\r\n \t<li><strong>U1XXX<\/strong> - Manufacturer Controlled DTC<\/li>\r\n \t<li><strong>U2XXX<\/strong> - Manufacturer Controlled DTC<\/li>\r\n \t<li><strong>U30XX<\/strong> - Control Module\/Power Distribution<\/li>\r\n \t<li><strong>U31XX<\/strong> - U3FXX - ISO\/SAE Reserved<\/li>\r\n<\/ul>","link":"https:\/\/repairsadvisor.com\/blog\/diagnostics-and-troubleshooting\/dtc-code-diagnostics\/u-codes\/","name":"U Codes","slug":"u-codes","taxonomy":"category","parent":28,"meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/repairsadvisor.com\/blog\/wp-json\/wp\/v2\/categories\/37","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/repairsadvisor.com\/blog\/wp-json\/wp\/v2\/categories"}],"about":[{"href":"https:\/\/repairsadvisor.com\/blog\/wp-json\/wp\/v2\/taxonomies\/category"}],"up":[{"embeddable":true,"href":"https:\/\/repairsadvisor.com\/blog\/wp-json\/wp\/v2\/categories\/28"}],"wp:post_type":[{"href":"https:\/\/repairsadvisor.com\/blog\/wp-json\/wp\/v2\/posts?categories=37"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
