"Great for learning the basics of UDS (0x10, 0x22, 0x2E, 0x34). However, this appears to be the 2013 draft – missing Annex C (example sequence charts). Also, page 47 has an OCR error: 'subFunction' is misprinted as 'subFuncti0n'. For production work, please buy the official standard." Search for ISO/DIS 14229-1
