Schematic for the ground speed sensorThis diagnostic code is associated with the ground speed sensor. The FMI 08 means that the main display module has determined that the signal frequency or the signal pulse width is not within the expected range. The possible causes of this diagnostic code are listed below:
The sensor has failed.
Intermittent connections or poor connections
Mechanical devices are loose.
The main display module has failed. This 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. Ensure that the diagnostic code of CID 0084 FMI 08 is active before performing this procedure.Note: Use the 146-4080 Digital Multimeter for the measurements in this procedure. Test Step 1. CHECK THE SENSOR.
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the sensor from the machine harness.
At the harness connector for the sensor, measure the resistance between signal contact 3 (wire C913-BU) and ground contact 2 (wire 210-BK).Expected Result:The resistance that is measured
