Principal Technical Analyst
The second day of Tulsa University CESE's class on HVEDR data begins the focus on specific engine manufacturers.
This morning, Ron Baade discussed and demonstrated the ECM and EDR data in Detroit Diesel and Mercedes Benz engines, including DDEC IV - DDEC 10, and the 2001 - 2008 MBE engines.
During the afternoon, I taught the section on Cummins ECMs, beginning with the 2002 ISX and ISM heavy duty engines, through the CM2250 and CM2150 EPA 2010 engines. Topics included data limitations, the effects of power failure, anomalies that have been found in the data, fault data (diagnostic trouble codes), and case studies.
In the evening, Ron, Jeremy Daily, and I went to Melton Trucking and began to prep the test trucks for tomorrow's testing. The trucks will include two 2012 Kenworths, and a 2012 Freightliner. In tomorrow's class, Dr. Daily will be presenting more information and examples of CAN data.
