Schematic of the rod end pressure sensor (Ejector cylinder)This diagnostic code is associated with the Rod End Pressure Sensor (Ejector Cylinder). The FMI 08 means that the ECM has determined that the signal frequency or the signal pulse width is not within the expected range.The output frequency of the pressure sensor is approximately 500 100 Hz. The duty cycle of the signal changes as the pressure sensor moves. The possible causes of this diagnostic code are listed below:
The sensor has failed.
Intermittent connections or poor connections
Mechanical devices are loose.
The ECM has failed. The failure of 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. Ensure that the diagnostic code of CID 3496 FMI 08 is active before performing this procedure.Note: Use the 146-4080 Digital Multimeter for the measurements in this procedure.System Response:When this diagnostic code occurs, a warning (Category 1) is shown on the monitor. The diagnostic code will cause the solenoids for the ejector control to be set to the minimum command. Control of the ejector cylinder will not return until the diagnostic code is inactive. The signal from the pressure sensor must be in the neutral position for at least 2 seconds.Test Step 1. CHECK FOR POWER AT THE SENSOR
Do not disconnect the harness connector from the sensor.
At the back of the harness connector for the sensor, insert a 7X-1710 Multimeter Probe along the voltage supply wire (contact 1).
Turn the key start switch and the disconnect switch to the ON position.
Measure the voltage from contact 1 to frame ground.Expected Result:The voltage is between +7 VDC to +14 VDC.Results:
OK - The voltage is between +7 VDC to +14 VDC. Proceed
