Information:
The 3054E engine has the following power supplies:
Data links
ECM
Fuel injection pump
Pressure sensors
Throttle position sensorData Links
Illustration 1 g00938680
Schematic for CAT Data Link (CDL) and J1939 CAN data link
The 3054E engines are equipped with three separate data links. The CAT Data Link (CDL) is used to configure the parameters in the ECM on the electronic service tool. The J1939 CAN data link is used for flash programming for the ECM. Refer to Illustration 1.The third data link is a proprietary CAN data link which is the communication link between the engine ECM and the Electronic Control Unit (ECU) on the fuel injection pump. Refer to Illustration 3.Power Supply for the ECM
Illustration 2 g01366976
Power supply for the ECM
The power supply to the ECM and the system is drawn from the 12 or 24 volt battery. The power supply for the ECM has the following components:
Battery
Disconnect switch
Key start switch
Fuses
Ground bolt
ECM connector
Machine interface connectorNote: The ground bolt is the only component that is mounted on the engine.The schematic for the ECM shows the main components for a typical power supply circuit. Battery voltage is normally connected to the ECM. The input from the key start switch turns on the ECM.The wiring harness can be bypassed for troubleshooting purposes. The display screen on the electronic service tool can be used to check the voltage supply.Note: Two wires are used to reduce resistance.Power Supply for the Fuel Injection Pump

(5) Fuel shutoff
(6) Pump supply -
(7) Pump supply +
(8) Signal for primary speed/timing sensor
(9) Unused The power supply for the ECM comes from the machine interface connector. The machine interface connector receives power from the power relay.Power Supply for the Pressure Sensors
Illustration 6 g01366978
Schematic for pressure sensors
The ECM supplies 5.0 0.2 DC volts to the ECM connector on each sensor. The power supply is protected against short circuits. A short in a sensor or a wiring harness will not cause damage to the ECM.Power Supply for the Throttle Position Sensor
Illustration 7 g00938717
Schematic for the throttle position sensor
The ECM supplies 8.0 0.4 DC volts through the ECM connector to the sensor. The power supply is protected against short circuits. A short in a sensor or a wiring harness will not cause damage to the ECM.
