i02493342
CID 0190 FMI 08
Conditions Which G enerate This Code:
The Electronic Control Module (ECM) detects the
following conditions:
•
The ECM detected an intermittent loss of signal
or a complete loss of signal from the primary
speed/timing
sensor for 2 seconds.
•
The engine has been running for more than three
seconds.
System Response:
If equipped, the warning light will come on and the
diagnostic code will be logged.
The ECM will use the signal from the secondary
speed/timing sensor.
Possible Performance E ffect:
The engine wi
ll be derated. If the signal from the
secondary speed/timing sensor is also lost, the
engine will shut down.
Troubleshooting:
Perform the f
ollowing diagnostic procedure: “Engine
Speed/Timing Sensor Circuit - Test”
Results:
•
OK – STOP.
i02527035
CID 0247 FMI 09
Conditions
Which Generate This Code:
The Electronic Control Module (ECM) detects the
following c
ondition:
•
Another controller has stopped transmitting a
J1939 speed
request (TSC1) incorrectly or another
controller has started transmitting a J1939 speed
request incorrectly.
System Response:
Some syste
m functions may not operate correctly.
Troubleshooting:
Perform the following diagnostic procedure: “CAN
Data Link Circuit - Test”
Results:
•
OK – STOP.
i02527036
CID 0247 FMI 12
Conditions Which Generate This Code:
The Electroni
c Control Module (ECM) detects the
following conditions:
•
There is an une
xpected loss of a continuous
J1939 Torque Speed Controller (TSC1) signal on
the J1939 data link.
•
The expected continuous TSC1 signal has never
been received on the J1939 data link.
System Response:
Engine speed
functions that are controlled through
TSC1 will be disabled until the fault is rectified and
the keyswitch is cycled through the OFF position and
the ON positi
on.
The engine speed will be reduced to a low idle. If
the engine i
s equipped with a secondary throttle,
the engine speed will change to the speed that is
demanded by the secondary throttle.
Thediagnosticcodewillbeactiveandthediagnostic
code will be logged.
Troubleshooting:
Check the co
nfiguration of the ECM. If the ECM for
the engine has been incorrectly configured to expect
a continuous TSC1 signal, remove “Continuous” for
theTSC1si
gnal on the main “J1939” screen on the
electronic service tool.
Perform th
e following diagnostic procedure: ““Use
the OEM information to determine the machine ECM
that provides the continuous speed signal. Refer to
the troub
leshooting procedures from the OEM to
diagnose the faulty speed signal.””
Results:
•
OK – STOP.
