Schematic of the "Stick Out Control Pressure" Sensor
This diagnostic code is recorded when the ECM reads the voltage of the circuit for the "Stick Out Control Pressure" Sensor as being below normal. The signal circuit of the sensor may be shorted to ground.The possible causes of this diagnostic code are listed below:
The signal circuit for the sensor is shorted to ground.
The sensor has failed.
The ECM has failed. A failure of the Machine ECM is unlikely. Note: The following test procedure may create other diagnostic codes. Ignore these created diagnostic codes and clear the diagnostic codes when the original diagnostic code has been corrected.Note: Ensure that the diagnostic code of CID 3545 FMI 04 is active before performing this procedure. Test Step 1. CHECK THE SENSOR.
Turn the disconnect switch and the key start switch to the ON position.
Ensure that the diagnostic code is active.
Observe the status of the diagnostic code. Disconnect the sensor from the machine harness. Expected Result:The CID 3545 FMI 04 diagnostic code remains active. The FMI 04 diagnostic code has not changed and the diagnostic code is still active.Results:
OK -
