AGCO 2×4 CANUSB

2026 AGCO EDT Diagnostic Software

 

Description

The measured rail pressure is over critical limit. Measured pressure is more than 1700 bar (24,656 psi). In normal conditions the pressure release valve (PRV) opens at a critical pressure (1600 to 1650 bar (23.206 to 23,931 psi)). In case PRV mechanical failure, EEM3 system continuously monitors rail pressure and if measured pressure more than 1700 bar (24,656 psi), engine will shutdown immediately.

 

Failure Mode Indicator

FMI 00 – Above normal operational range – most severe.

 

Failure Mode

Fault code is stored and warning lamp is activated. The engine will stop immediately. CAN message indicates, that shutdown is pending.

 

Possible Cause

• High pressure pump is not working correctly
• Rail pressure sensor wiring is defective
• Rail pressure sensor power supply is not correct
• Rail pressure sensor is defective
• Pressure release valve (PRV) is not working correct
• Control unit is defective

 

Diagnosis and Solution

• Check the high pressure pump:
• Look for possible high pressure pump faults and inspect accordingly (such as faults with wiring and connectors).
• Check the high pressure pump operation with Service Tool test function or have the pump inspected by an authorized Bosch service dealer.
• Check the rail pressure sensor wiring, connectors and contact surfaces of the connector pins (possible oxidation).

 

Rail Pressure Sensor

• Check the 5 V power supply to the sensor.

 

Rail Pressure Sensor

Check the rail pressure sensor operation.

 

Rail Pressure Sensor

Check the ECU operation with another EEM3 controller. If the system is functional and the fault is not active with the replacement ECU, then the original ECU is defective.

 

ECU Replacement

In case of damaged pressure release valve (PRV), high pressure pump or wiring harness, replace damaged parts according service manual.

NOTE: High pressure parts removal, inspection and replacement should be performed only by qualified injection system service personnel. Special instructions may apply.

Failure Mode Indicator

FMI 00 – Above normal operational range – most severe.

 

Failure Mode

Fault code is stored and warning lamp is activated. The engine will stop after 30 seconds. CAN message indicates, that shutdown is pending.

 

Possible Cause

• The fan belt is slipping or the belt is broken
• Cooling system is not completely filled
• Water pump is defective
• Cooling system is clogged
• Thermostat is defective or removed (double acting thermostat)
• Thermostat is upside down.
• Radiator filler cap is not pressure tight
• Engine is overloaded
• Coolant temperature sensor wiring is defective
• Coolant temperature sensor is defective
• Control unit is defective

 

Diagnosis and Solution

Find cause for the overheating indication:

• Check the fan belt and the belt tension.
• Check the coolant level.
• Check condition of the radiator.
• Check the mechanical condition of the engine.
• Check the coolant temperature sensor wiring, connectors and contact surfaces of the connector pins (possible oxidation).
