Relay (Starter Motor)
This diagnostic code is associated with starter motor relay. FMI 06
Shorted to Ground.
means ECM has determined relay current is above normal due to relay
energizer circuit shorted to ground, failed relay, or failed ECM (such a
failure is unlikely).
0473 03
Pressure Sensor (Brake
This diagnostic code is associated with brake charging pressure sensor.
FMI 03 means ECM has determined sensor circuit is above normal.
Charging) Voltage
Possible causes of this diagnostic code are:
Above Normal.
Sensor signal circuit is open.
Sensor signal circuit is shorted to +batt circuit.
Sensor has failed.
Power circuit or ground circuit has failed.
ECM has failed (such a signal is unlikely).
ECM will log diagnostic code. When this diagnostic code occurs, brake
oil diverter solenoid is turned off.
0473 04
Pressure Sensor (Brake
This diagnostic code is associated with brake charging pressure sensor.
Charging) Shorted to
FMI 04 means ECM has determined position sensor circuit voltage is
Ground.
below normal due to sensor signal circuit shorted to ground, failed
sensor, or failed ECM (such a failure is unlikely). When this diagnostic
code occurs, brake oil diverter solenoid is turned off.
0490 03
Switch (Pilot ON/OFF)
This diagnostic code is associated with implement lockout switch.
Voltage Above Normal.
Switch is connected to two ECM inputs. One contact is open and other
contact is grounded during proper operation.
Possible causes of this diagnostic code are:
Normally open contact and normally closed contact
are both open.
Contact currently closed to ground is shorted to
+batt circuit.
Machine ECM will log diagnostic code. When this diagnostic code
occurs, implements are locked.
0490 04
Switch (Pilot ON/OFF)
This diagnostic code is associated with implement lockout switch.
Shorted to Ground.
Switch is connected to two ECM inputs: "Normally Open" and
"Normally Closed." One input is open and other input is grounded
during proper operation. FMI 04 means ECM has determined
"Normally Open" and "Normally Closed" circuits are both grounded.
Machine ECM will log diagnostic code. When this diagnostic code
occurs, implements are locked.
