The diagnostic trouble code triggers the alarm level:
“Information”. This diagnostic trouble code does not
necessarily have any real meaning. It is often stored
by chance when the main switch is turned (ignition ON

Diagnostic trouble code BCU 302240.31 is saved
when the basic control unit detects an erroneous
signal in the circuit of the control unit identification. An
erroneous test signal is detected during the
initialization of the control unit via the wiring harness
bridge (cable 544) from pin 37 (connector X483/2) to
pin 25 (connector X483/1). This diagnostic trouble
code does not necessarily have any real meaning. It is
often stored by chance when the main switch is turned
(ignition ON and OFF). For this reason, diagnosis only
needs to be performed if one or more related faults
occur in conjunction with this code.

Diagnostics
NOTE: The following are possible causes:
• This diagnostic trouble code may occur without there being any problem at the wiring harness connector. For this
reason, delete this diagnostic trouble code after starting the engine, then do an operational check. If this
diagnostic trouble code re-appears after the operational check, this indicates a wrongly connected control unit.
• Wrong control unit connected to BCU connector X483/1 and X483/2.
• Open circuit (cable 544).
• Defective basic control unit (BCU).

BCU 303041.02 — Stepper Motor Coil 1, Open Lead
Diagnostic trouble code BCU 303041.02 is saved
when no impulses are received from the stepper motor
circuit (coil 1). This indicates that the stepper motor’s
circuit is open. This diagnostic trouble code does not
necessarily have any real meaning. It is often stored
by chance when the main switch is turned (ignition ON
and OFF). For this reason, diagnosis only needs to be
performed if one or more related faults occur in
conjunction with this code.

2. Sender/pump adjustment:
Position the sender/pump unit, to enable the float arm to sit into a well leading away
from the pump locating socket in the base of the tank. For exact positioning, use a
multimeter. The empty-position Ohm-value, when the sender/pump unit is pressed
down against its spring, needs to be 15 to 18 Ohm.
The pump socket can be seen from the underside of the tank, showing the position
and direction of the sender/pump guide for the sender arm.
NOTE: If the engine is running, the fuel gauge sender is connected to the wiring
harness and the lever of the sender moves from the "Empty" to the "Full" position, it
takes a few minutes before the display indicates the new fuel level. Inside the BIF a
delay relay (5 to 10 minutes) is installed.

BIF 000186.16 — INFORMATION FOR OPERATOR: Warning, Rear PTO Speed
Diagnostic trouble code BIF 000186.16 is intended
only to provide information. It appears together with a
visual warning (540, 540E or 1000 rpm light and a
flashing yellow CAUTION light) whenever the PTO
speed exceeds 620 (+/-10). This warning is
independent of the selected PTO speed (540, 540E or
1000 rpm).

BIF 000190.02 — No Signal From Engine Speed Sender
Diagnostic trouble code BIF 000190.02 is saved when
no engine speed signal is transmitted to the instrument
panel (via the 29 BIT CAN BUS) while the ignition is
ON and engine oil pressure exists. This diagnostic
trouble code does not necessarily have any real
meaning. It is often stored by chance when the main
switch is turned (ignition ON and OFF). For this
reason, diagnosis only needs to be performed if one or
more related faults occur in conjunction with this code.
LX16167,0000059 –19–03APR02–1/1
Diagnostics
The following are possible causes:
• Defective engine speed sender.
– Engine speed sender B01 for tractors without engine control unit or with ECU level 1: Diagnostic trouble code

– Engine speed sender B72 or B74 for tractors with ECU level 4 (Bosch VP44 injection pump): Diagnostic
trouble codes ECU 000636.02, ECU 000636.08, ECU 000636.10, ECU 000637.02, ECU 000637.08 and/or
ECU 000637.10 take priority.
• Defective engine speed sender (B01) line connections (lead 531 or 325).
• Defective engine oil pressure sender (BIF erroneously receives an oil pressure signal and expects a speed
signal).

EPC 306060.31 — Engine Control Unit or Basic Control Unit has Stopped Transmitting
Data (Engine Speed)
Diagnostic trouble code EPC 306060.31 is saved when
there is a problem with the transference of data
between the ECU/BCU and the transmission control
unit. Reception of engine speed data via the CAN BUS
is intermittent or non-existent (intermittent reception
could be due to a loose wire). This diagnostic trouble
code triggers the alarm level: “Information”. In the case
of tractors with Delphi/Lucas injection pump (Level 1),
the transmission control unit (EPC) receives the engine
speed from the BCU (via CAN BUS). In the case of
tractors with Bosch VP44 injection pump, DE10
injection pump or HPCR fuel system, the transmission
control unit (EPC) receives the engine speed from the
engine control unit (ECU) via the CAN BUS.
