Main beam RH
Error identification
The current consumption on the control unit output has exceeded 6A.
 

Cause
Short circuit in the relay for current consuming equipment R19 or in the cable harness.
 

Notes
Right-hand main beam is inoperative. Every time the function is activated, the current consumption on the control unit output is checked. If the current consumption is too high, the output is switched off and a fault code is registered. Right dipped beam will come on as replacement lighting.
If a fault is detected in the main beam circuit (right main beam), dipped beam will be switched on instead. The lights adjustment motor will then adjust the headlamp downwards as far as it will go due to internal connection between the dipped beam and the lights adjustment motor.
 

Action
Check the bulbs. Also, check the number of connected lamps in circuit. Check whether there is a short circuit to earth.

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.
