Detroit Diesel Electronic Control System

Operation

Detroit Diesel Electronic Control System Operation

NOTE:

This engine is equipped with DDEC software. This software

generally assures optimal engine performance. The installation of software
upgrades may cause minor changes in features and engine performance.

Since the DDEC system is electronic, a battery is required to operate the computer.
The system operates at 12 volts. However, in the event of a power supply
malfunction, the system will continue to operate at reduced voltage. When this
occurs, the AWL (Check Engine) will come on.

The engine will only operate at reduced rpm until the battery voltage reaches a
point where the MCM will no longer function and the engine shuts down.
Should the AWL (Check Engine) come on for any reason, the vehicle can still be
operated and the driver can proceed to the required destination.

This condition

should be reported to an authorized Detroit™ distributor or dealer.
