While providing significant benefits to vehicle operation and emissions, on board diagnosis comes at a cost. In many cases the additional cost comes in the form of reduced optimal performance. Often the additional cost can be mitigated by considering the OBD requirements early in the development stages. In this presentation we show these trade-offs in a number of case studies. We will point out where the ability to diagnose comes at the cost of suboptimal performance, and where system design decisions can facilate the OBD task.

Some the OBD-II regulations have been around for a long time or seem to be intuitively obvious. It is easy to assume to assume that everyone knows how to implement them correctly, that is, until someone actually reads the words and tries to do it. Most often, these issues come up when modifying existing OBD features, not when creating completely new ones. This presentation contains a few examples of features that should have been easy to implement, but turned out not to be easy or simple. Presenter Paul Algis Baltusis, Ford Motor Co.

Sensing exhaust gas temperature is a key component in diesel after treatment systems for both control and diagnostics. Accuracy varies significantly depending upon the sensing technology and implementation in the system. Prior published work has demonstrated that resistance based temperature sensors are not able to achieve the system accuracy required for advanced diagnostics over the life of the emission system. This presentation will show that it is feasible to achieve better than �10�C end of life system accuracy by means of active thermocouple technology. Results from tests at Michigan Technological University will be used to illustrate diagnostic uncertainty related to the application of temperature sensors and a specific DOC/DPF example will be used to show the benefits of accurate temperature based diagnostics.

Revisions to the California OBD-II diesel regulations required many updates to various SAE and ISO on-board diagnostic standards; these include major revisions to SAE J1979, J1699-3, J2012 and J1930. This presentation is intended to review the background for these changes as well as the revisions made in these documents. Presenter Robert Gruszczynski, Volkswagen of America
