CID 0247 F MI 09 J1939 Datalink,
Abnormal Upda
te
Conditions Which Generate This Code:
The ECM has de
tected a loss of communications
with another device on the J1939 data link.
System Respo
nse:
Some system functions may not operate properly.
The ECM will generate a CID 247 FMI 09 diagnostic
code on the Data Link. The diagnostic code will be
displayed on
a diagnostic screen of the electronic
service tool.
Perform the f
ollowing diagnostic procedure:
“Troubleshooting, “CAN Data Link Circuit - Test”.”
Results:
•
–STOP.

CID 025 3 FMI 0 2 Incorrect EC M
Software
Conditions Which Generate This Code:
The persona
lity module is the software that is
loaded into the ECM in order to determine the
power and torque outputs for a particular engine
model and/
or a particular engine application. The
engine’s personality module is loaded by the factory.
A replacement personality module can be loaded
into the EC
M. The diagnostic code 0253 indicates
that the personality module is neither the original
personality module nor a replacement of the original
personal
ity module.
Note: The personality module is a flash personality
module. The per
sonality module is installed into the
ECM by flash programming.
System Respon
se:
The ECM will not log any diagnostic code except
diagnostic co
de 0253. The diagnostic code may be
viewed on a display module or on the electronic
service tool. As a result of this code, the fuel injection
pump is disab
led for the engine. The engine will not
start, and the electronic service tool will not be able
to reset the diagnostic code in order to allow the
enginetosta
rt.
Possible Pe rformance Effect:
•
Engine shutdown
Troubleshoo
ting:
Check the part number of ECM Personality Module.
Ensure that
the personality module part number
agrees with the original engine arrangement.
Expected Re
sult:
The correct personality module is installed in the
ECM.
Results:
•
OK – The correct personality module is installed
in the ECM. STOP.
•
Not OK – The correct personality module is not
installed in the ECM.
Repair: Reprogram the ECM with the correct
personality module. Refer to Troubleshooting,
“Flash Pro
gramming”.
STOP.

CID 0262 FMI 03 5v Sensor
Power Supp
ly, Voltage More
Than Normal
Conditions Which G enerate This Code:
The Electronic Control Module (ECM) detects all of
the following conditions:
•
The ECM reads signal voltage that is above
normal.
