AUTOSARは、ISO、IEC、ITUと情報交換契約を結んでいません。
AUTOSAR文書には、ISO、IEC,ITU記述を全文引用することはできません。
WTO/TBT協定に基づき、国際的な調達は国際規格との差異を記述することにより文化依存しない仕様を目指します。
ISO、IEC、ITU文書を合わせて読むと技術内容は理解できます。　
CAN、OSEK/VDX OS、DIAGは、ISO定義を先に確認しましょう。　　
OSEK COM、OSEK NMなどはISOの規定から基本的な部分で定義を変えています。
変更している部分を仕様等で明記するか、ISOを改定するとよいでしょう。　

AUTOSARの参考文献欄の改定が進んでいません。　
Glossary用語定義の網羅性が低いです。
本文を読む前に確認するとよいかもしれません。
本文を読んでから確認してもよいかもしれません。
