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.
