Non-Routine Maintenance Section 5 – Procedures
SPN FMI
91 3, 4, or 11 Sensor error accelerator pedal
Check wiring, check accelator pedal sensor and if necessary replace it, check connection cable and if
necessary repair or replace it
97 3, 4, or 12
Fuel filter water level sensor: the voltage of sensor measured by ECU
is out of the target range high or low.
Drain water out from pre-filter. Check wiring, if sensor is not working, check sensor and if necessary
replace it, check connection cable and if necessary repair or replace it
100 0, or 1 Oil pressure is either above or below the target range
Check oil level, check engine for oil leckage, measure oil pressure external to evaluate sensor value,
clean suction pipe inlet mesh in oilsump
110 0
Coolant temperature: the coolant temperature calculated by ECU is
above the target range.
Clean radiator, check fan drive, check coolant level, check cooling system in general, check thermostat
function.
105 0
Charge air temperature downstream calculated by ECU is above the
target range
Check CAC system and clean it. Check fan functionality. Check cooling perfomance with temperature
measurement.
111 1
Coolant level: the coolant level calculated by ECU is underneath the
allowed minimum
Check coolant level, inspect cooling system for leakage and if necessary repair it, check sensor and
wiring
523009 9, or 10
Rail pressure relief valve: is open more frequently, or longer than
what the technical specification allows
Change rail pressure relief valve
639, 1231,
or 1235
14
CAN bus 0, 1, or 2: the ECU is not allowed to send messages,
because the status "BusOff" is detected
Check wiring of CAN bus and if necessary repair it, check connection cable and if necessary repair or
replace it, check resistance in CAN lines (60 Ohm)
630 12
Access error: the ECU finds an error during the access to its
EEPROM memory or works with an alternative value
ECU not programmed, EEPROM is defective, ECU is defective: reprogram ECU and if necessary
replace it
1079, 1080,
or 523601
13 Sensor supply voltage monitor error (ECU), Error in sensor voltage.
Check wiring of external components, check working voltage and if necessary correct it, check
connection cable and if necessary repair or replace it, if error is not removable, change ECU
168
0, 1, 2, 3, or
4
Battery voltage: the voltage measured by ECU is out of the target
range; either too high, too low, or eratic.
Check alternator, contact resistance, safety fuses, too high load in energy system, check battery and
connections, check cables and if necessary clean, repair or replace component as required.
1109 2 Engine Shut Off demand has been ignored by the user Warranty relevant, Additional error must be set
677
3, 4, 5, or
12
Starter relay; short circuit to B+ or B-, Open circuit, or powerstage
over temperature
Check wiring and start relay and if necessary replace it, check connection cable and if necessary repair
or replace it
523550 12 Start information to Starter (T50-switch) erratic, on too long.
Check wiring, if sensor not working, check start switch and if necessary replace it, check connection
cable and if necessary repair or replace it
523612
3, 4, 12, or
14
ECU reported internal software error
Check error memory for other errors. Check wiring, check connected sensors and actuators. Re-flash
the ECU. If error is still active replace ECU.
523698 11
Shut off request from supervisory monitoring function, Engine Shut
Off due to supervisory function
Warranty relevant,Additional error must be set
5763
0, 1, 3, 4, 5,
6, 7, or 11
Actuator error EGR-Valve; signal out of range Check wiring and repair or replace if necessary, check actuator/EGR and if necessary replace it
523982 0, 1 Powerstage diagnosis disabled; low or high battery voltage Check wiring, check alternator, check cables and repair or replace if necessary
523906
3, 4, 5, or
12
ECU detects open load on the electric fuel feed pump output, too
high temperature in powerstage of fuel pump circuit, or short to B+
or B-
Check wiring of the fuel feed pump circuit including relay, if necessary repair or replace wirirng
524057 2 Electric fuel pump; fuel pressure build up error
Check low fuel pressure system (fuel feed pump, relay , fuse, wiring, sensor) and if necessary repair or
replace it
524108 9 Missing CAN message of EGR throttle valve
Check CAN Bus wiring (Bus sheduling, polarity, short circuit, power interrupt), test protocol of receiver,
check CAN functional range, check actuator
524109 9 Missing CAN message of EGR throttle valve
Check CAN Bus wiring (Bus scheduling, polarity, short circuit, power interrupt), test protocol of receiver,
check CAN functional range, check actuator
