0368 02
Switch (Transmission
The transmission auto/manual HMU switch has three inputs to the
AUTO/MAN) Data
powertrain ECM. During normal operation, one input is grounded and
Erratic, Intermittent, or
the other inputs are open. If the powertrain ECM detects more than one
Incorrect
input is grounded, a circuit failure is present. This code is generated
when there is a faulty harness.
0368 03
Switch (Transmission
The transmission auto/manual HMU switch has three inputs to the
AUTO/MAN) Voltage
powertrain ECM. During normal operation, one input is grounded and
Above Normal or
the other inputs are open. This diagnostic code of FMI 03 means that
Shorted High
the powertrain ECM has determined that all contacts are open.
0444 03
Starter Relay Voltage
This diagnostic code is associated with the start relay. The FMI 03
Above Normal or
means that the powertrain ECM has determined that the voltage of the
Shorted High
relay circuit is above normal. This code is generated when the relay
circuit is shorted to the +battery circuit or the powertrain ECM has
failed. When this code is generated, the powertrain ECM will turn off
the current to the failed relay.
0444 05
Starter Relay Current
This diagnostic code is associated with the start relay. The FMI 05
Below Normal or Open
means that the powertrain ECM has determined that the current of the
Circuit
relay is below normal. This code is generated when the energizer circuit
of the relay is open, the return circuit of the relay is open, the relay has
failed, or the powertrain ECM has failed. When this diagnostic code is
active, the powertrain ECM will turn off the current to the failed relay.
0444 06
Starter Relay Current
This diagnostic code is associated with the start relay. The FMI 06
Above Normal or
means that the powertrain ECM has determined that the current of the
Grounded Circuit
relay is above normal. This code is generated when the energizer circuit
of the relay is shorted to ground, the relay has failed, or the powertrain
ECM has failed. When this diagnostic code is active, the powertrain
ECM will turn off the current to the failed relay.
0562 02
Caterpillar Monitoring
This diagnostic code is associated with the Cat Data Link. The FMI 02
System Data Erratic,
means the powertrain ECM is experiencing intermittent
Intermittent, or Incorrect
communications with the Caterpillar Monitoring System. This
intermittent communication may be the result of a wiring problem or
other interruption of the Cat Data Link.
0562 09
Caterpillar Monitoring
This diagnostic code is generated when the powertrain ECM cannot
System Abnormal
communicate with the Caterpillar Monitoring System via the Cat Data
Update
Link. The Cat Data Link is an input and an output of all modules. The
Cat Data Link is designed to enable communications for all electronic
control modules and service tools. The Cat Data Link is not a visible
component. The data link consists of internal control circuits and the
connecting harness wiring. Other FMI 09 diagnostic codes may help
determine the possible causes of the diagnostic code. This code is
generated when there is powertrain ECM Software incompatibility,
wiring harness failure, or the powertrain ECM has failed.
