The DDC series 60 engine is a 6-cylinder, four-
cycle, 14.0 liters Detroit Diesel series 60 engine, 
equipped with an electronic control system 
(DDEC VI). 

Complete maintenance and repair information 
on the engine will be found in the current 
DETROIT DIESEL SERIES 60 2007 ON-
HIGHWAY SERVICE MANUAL 6SE2007. This 
essential manual contains complete instructions 
on operation, adjustment (tune-up), preventive 
maintenance and lubrication, parts verification, 
repair or replacement. This manual’s sections 
cover complete systems such as: 

•  Engine main assembly; 
• Fuel 

system; 

• Lubrication 

system; 

• Cooling 

system; 

•  Fuel, lubricating oil and coolant; 
•  Air intake system; 
• Exhaust 

system; 

•  Exhaust gas recirculation components; 
• Electrical 

equipment; 

•  Operation and verification; 
• Engine 

tune-up; 

• Preventive 

maintenance; 

• Storage; 
 
Refer to Series 60 DDEC VI Troubleshooting 
Guide published by Detroit Diesel for more 
complete information on diagnosis of 
components and system problems. 

Procedures for engine removal and installation 
are given at the end of this section. The DDEC 
system is self-diagnostic. It can identify faulty 
components and other engine-related problems 
by providing the technician with diagnostic 
codes. 

2.1  DDEC VI SYSTEM 
DDEC VI (Detroit Diesel Electronic Control) is a 
system that monitors and determines all values 
required for the operation of the engine. A 
diagnostic interface is provided to connect to an 
external diagnosis tester. Besides the engine 
related sensors and the engine-resident control 
unit, the Motor Control Module (MCM), this 

system has a chassis-mounted control unit for 
vehicle engine management, the Common 
Powertrain Controller (CPC). The connection to 
the vehicle is made via a CAN interface which 
digitally transmits the nominal values (e.g. 
torque, engine speed specification, etc.) and the 
actual values (e.g. engine speed, oil pressure, 
etc.). 
DDEC VI controls the timing and amount of fuel 
injected by the electronic unit injectors (EUI). 
The system also monitors several engine 
functions using electrical sensors, which send 
electrical signals to the Motor Control Module 
(MCM). The MCM computes the electrical 
signals and determines the correct fuel output 
and timing for optimum power, fuel economy 
and emissions. The MCM also has the ability to 
display warnings or shut down the engine 
completely (depending on option selection) in 
the event of damaging engine conditions, such 
as low oil pressure or high engine temperature. 

2.2 HARNESSES  
There are two major harnesses: the Engine 
Harness (EH) and the Vehicle Interface Harness 
(VIH). The Engine Harness is installed at the 
Detroit Diesel factory and is delivered connected 
to all engine sensors, the fuel injection system, 
and the MCM. 
The OEM supplied Vehicle Interface Harness 
connects the CPC to other vehicle systems.
