Detroit Diesel Electronic Controls System

Detroit Diesel Electronic Controls System

All Detroit™ Gen 5 Heavy Duty engines are equipped with an electronic control
system called Detroit Diesel Electronic Control® (DDEC®). The DDEC ® system
monitors the functions that regulates the Detroit™ powertrain.
The following sections will be covered in this chapter:
• Detroit Diesel Electronic Control System Operation

- Common Powertrain Controller
- Motor Control Module
- Aftertreatment Control Module
- Transmission Control Module
- Check Engine Indicator
- Stop Engine Indicator
- Stop Engine Override
- Engine Power Reduction

• Detroit Diesel Electronic Control System Features

- Cruise Control
- Data Recording
- DDEC 

®

 Protection System

- Engine Brake
- Idle Shutdown Timer

Detroit Diesel Electronic Control System Operation

Detroit Diesel Electronic Control System Operation

Detroit™ Gen 5 Heavy Duty engines are equipped with Detroit Diesel Electronic
Control® (DDEC®) software. This software assures optimal engine performance.
The installation of software upgrades may cause minor changes in features and
engine performance.
During normal operation the DDEC ® system requires 12 volts to operate.
However, in the event of a power supply malfunction, the system will continue to
operate at reduced voltage. When this occurs, the Check Engine Indicator will be
activated. The engine will only operate at reduced rpm until the battery voltage
reaches a point where DDEC ® will no longer function and the engine shuts down.
The engine and powertrain operation is monitored and controlled via a series of
sensors, electronic valves, solenoids and switches. The system has three to four
control modules; four if equipped with a Detroit Transmission:
• Common Powertrain Controller (CPC)
• Motor Control Module (MCM)
