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.

1 Check fuses F38 and F12.

2 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.

3 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.

Display Area
The Special Tests display area has two columns: Description – Provides the name of the parameter
State – Displays the current state of the parameter: "Not Installed", "Active", or "Not Active".

The Special Tests display area contains all of the available special tests for the currently selected ECM. Each ECM has one or more special tests displayed. However, only one test may be selected at a time.
 

Buttons  

The buttons available in the Special Tests screen are: Start – After selecting one of the parameters, click this button to begin testing. This button is disabled until after the Stop button is clicked.
Stop – Click this button to stop the selected special test in progress. This will change the state of the test. The Stop button is disabled until the Start button has been clicked.

1 The flanged shaft (1), taper lock sleeve (5) and the spherical roller bearing (6) should all be dry and
free of grease.

2 Pre-assemble the bearing housings (4 and 7) with taper lock sleeve (5) and the spherical roller
bearing (6).
Place this complete assembly plus the felt strips (3 and 8) and the spacer (2) on the shaft end.
3. Fit the M 12 x 100 bolts through the bearing assembly and the spacer (2) and fit into the assembly cover.
4. From serial no. …: Tighten the M 65 x 2 face-end slotted nut (10) to 55 Nm using the special tool (part no. 181 614.0), then continue tightening by 64° and then to the next slot position, matching it with the securing tab (9). Tap tab down into the slot.


Up to serial no. …:
Tighten the M 60 x 2 face-end slotted nut (10) to 45 Nm using the special tool (part no. 180 143.0),
then continue tightening by 64° and then to the next slot position, matching it with the securing
tab (9). Tap tab down into the slot.


5. Refit the grease pipe.
Remove the wooden block and refit the cover.

6. Slide on the V-belt pulley, align it and lock it in position with the gib head key.
If necessary, Installing the threshing drum reduction gearbox, see page 7.7.11

7. Install the V-belt (K) and adjust it – see page 7.3.11, Installing and adjusting the accelera
tor drive belt (24).
Tension the jockey pulley (P) in the same manner.

8. Refit the guard and the right-hand wheel.

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.
