Detroit Diesel Series 60 EGR Technician's Manual
Detroit Diesel Series 60 EGR Service Manual

The Series 60 engine is entering its 14th year!
Since its introduction in 1987, over 729,000 Series 60 engines have been introduced in the market. The technological changes that have occurred during those 14 years have resulted in a different type of engine, requiring a different class of technicians. Today’s technician is required to have computer skills, excellent comprehension of the written word and possess an extensive diagnostic understanding of the various technological systems and components. Today’s technician must perform at a higher level of efficiency and competency than their predecessors and at the same time furnish professional quality support.

Detroit series 60 egr valve As the leader in engine computer systems and technology, Detroit Diesel Corporation remains focused on providing excellence in products, service support and training. As products become more and more advanced, today’s technicians must become specialized in multiple areas. This manual is designed with that thought in mind. This Series 60 EGR Technician’s Guide will provide you with concentrated information that will allow you to excel in EGR technology.

Detroit series 60 egr valve location The Series 60 EGR Technician’s Guide covers the October 2002 through current production Series 60 EGR engines. After completing this guide you will:

  1. Understand the function of the Series 60 EGR engine components and their interdependence
  2. Understand Series 60 EGR operating modes
  3. Recognize the logic, component, and protection codes logged within the ECM
  4. Learn the acceptable pressure output values from a Variable Pressure Output Device (VPOD)
  5. Be able to record, playback, save, and e-mail a DDDL snapshot
  6. Apply your understanding of the EGR system logic to review DDDL diagnostic snapshots

Detroit 60 series egr valve problems The Series 60 EGR Technician's Guide is intended to be used by a qualified service technician familiar with Detroit Diesel electronically controlled (DDEC) diesel engines and to provide a better understanding of the EGR system to improve the diagnosing of a Series 60® EGR system.

Ask the driver to answer the following questions before attempting to repair an intermittent problem, or a problem with symptoms but no diagnostic codes. Use this and the response as a guideline. Refer to Questionnaire Response Guideline found on page 1–6.

  1. How often does the problem occur? Can you and the driver take the vehicle and demonstrate the problem in less than 30 minutes?
  2. Has the vehicle been to other shops for the same problem? If so, what was done there?
  3. Did the radio, dash gages, or lights momentarily turn OFF when the problem occurred?
  4. Does the problem occur only at specific operating conditions? If so, at what load? Is it light, medium, or heavy?
  5. Does the problem occur at a specific engine operating temperature? If so, at what engine temperature?
  6. Does the problem occur at a specific engine operating altitude? If so, at what altitude?
  7. Does the problem occur only when above or below specific outside temperatures? In what temperature range?
  8. Does the problem occur during other conditions e.g. during or after rain, spray washing, snow?
  9. Did the problem occur at a specific vehicle speed? If so, at what vehicle speed?
  10. Does the problem occur at specific engine RPM? If so, at what engine RPM?

Detroit Diesel Series 60 EGR Service Manual EGR (exhaust gas recirculation) allows a percentage of the exhaust gases to remix with the air coming into the intake manifold. The exhaust gas dilutes the incoming air, displacing some of the oxygen in the air. Less oxygen results in a slower burn and a reduced peak cylinder temperature which reduces NOx (nitrogen oxides).
