SERIES 60 DDEC VI TROUBLESHOOTING GUIDE
SAFETY INSTRUCTIONS
To reduce the chance of personal injury and/or property damage, the instructions contained in this
troubleshooting manual must be carefully observed. Proper service and repair are important to the
safety of the service technician and the safe, reliable operation of the engine.
If part replacement is necessary, the part must be replaced with one of the same part number or
with an equivalent part number. Do not use a replacement part of lesser quality. The service
procedures recommended and described in this manual are effective methods of performing
repair. Some of these procedures require the use of specially designed tools. Accordingly, anyone
who intends to use a replacement part, procedure or tool which is not recommended, must first
determine that neither personal safety nor the safe operation of the engine will be jeopardized by
the replacement part, procedure or tool selected.
It is important to note that this manual contains various hazard notices labeled “Warnings,
“Cautions" and "Notices" that must be carefully observed in order to reduce the risk of personal
injury during repair, or the possibility that improper repair may damage the engine or render it
unsafe. It is also important to understand that these “Warnings,” "Cautions" and "Notices" are not
exhaustive. It is impossible to warn personnel of all the possible hazardous consequences that
might result from failure to follow these instructions.
A LETTER TO THE TECHNICIANS
Technicians today are required to have computer skills, excellent comprehension of the written
word and possess an extensive diagnostic understanding of the various technological systems and
components. Technicians today must perform at a higher level of efficiency and competency than
their predecessors and at the same time furnish professional quality support.
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, technicians must become specialized in multiple areas. This
manual is designed with that thought in mind. The Detroit Diesel 2007 Electronics Controls
Troubleshooting Guide will provide you with concentrated information that will allow you to
excel in 2007 Electronics Controls technology.
