Power Sources

Introduction
The engine supplies power to the ECM. The ECM
powers the following components:
• All sensors on the engine and the clean emissions
module
• The Nitrogen Oxide (NOx) sensors
• The suction control valve for the fuel injection
pump
• The solenoid for the wastegate
• Diagnostic connector
• Electronic unit injectors
The glow plugs are powered directly from the battery.
The engine ECM also controls power to the DEF
system. The engine ECM does not power the DEF
system.
