A Second-Generation Approach to Service of Electronic Systems

The heavy duty trucking industry is in need of a revised strategy for supporting electronic diesel engine controls. This paper outlines an approach to diagnostics that not only utilizes existing tools but also introduces several concepts that can be used to improve today's situation. The following key areas are examined: tools supported by engine manufacturers, procedures to update these tools in the field and techniques which can be employed to facilitate more standard support for the entire industry. This approach is not intended to revolutionize the way service and diagnostics are handled today but rather to suggest practical enhancements to already-established support systems in a way that is realistic and achievable.
