The measurement has failed inside the ECU.

Failure Mode Indicator

FMI 02 - Data erratic, intermittent or incorrect.

 

Failure Mode

Fault code is stored and warning is activated. CAN message indicates active fault. Engine functions dependent on the ECU temperature are not active.

 

Possible Cause

• ECU hardware defect.

 

Diagnosis and Solution

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

Possible causes

The filtered battery supply voltage is above 15.5 V

The alternator voltage regulator is faulty

The instrument panel voltage filter system is faulty



Consequences

There is a risk of overvoltage causing damage to the tractor electrical components.



D121 error code: diagnostic file
Check fuses F38 and F12.
Checking the voltage supplied by the two alternators

Test the voltage between terminal 1 of connector X192 or terminal 1 of connector X193 and the earth.



Note: 
For more information about the alternator test, refer to the workshop manual.

Erase any errors in the instrument panel and check that the error code does not re-appear.

Change the alternator voltage regulator. Repair the electrical fault if necessary.

Replace the instrument panel. The condenser inside the instrument panel may be faulty.


Note: 
Before replacing the instrument panel, check to make sure that the two voltage input terminals for the instrument panel are correct. Terminal 1 of connector X55 is connected to a + supply when the ignition is switched on. Terminal 68 of connector X55 is connected to a permanent + supply.


Carry out a test, while checking to ensure that the error code does not re-appear.

AGCO 2x4 930203400 CANUSB

MPROP control: High side short circuit to HIGH SOURCE
The EEM monitoring system has detected a battery short circuit on the high pressure pump control (MPROP) high side. The fault was detected in the afterrun when the MPROP control was turned off.

Possible causes are:
The solenoid valve connector is defective.
The solenoid valve wiring is defective.
The solenoid valve is defective.



Reaction in EEM
The FC is stored and the warning lamp is activated. The CAN message indicates an active fault.



Solution
First save the error log and then do the procedure that follows:
Examine the solenoid valve wiring, the connectors and the contact surfaces of the connector pins (possible oxidation).
Measure the high side from the wiring terminal to the engine ground, to see if there is a battery short circuit.
Test the operation with another MPROP solenoid valve to see if the solenoid valve is defective.


MPROP control: low side short circuit to ground
The EEM monitoring system has detected a short circuit to ground on the high pressure pump control (MPROP) Low side. Possible causes are:
The solenoid valve connector is defective.
The solenoid valve wiring is defective.
The solenoid valve is defective.



Reaction in EEM
The FC is stored and the warning lamp is activated. The engine power is reduced (Degradation 3). The CAN message indicates an active fault.



Solution
First save the error log and then do the procedure that follows:
Examine the solenoid valve wiring, the connectors and the contact surfaces of the connector pins (possible oxidation).
Measure the low side from the wiring terminal to the engine ground, to see if there is a short circuit to ground.
Test the operation with another MPROP solenoid valve to see if the solenoid valve is defective.
