Schematic of the Blade Control Handle BaseThis diagnostic code is associated with the Blade Control Handle Tilt Position sensor (X-axis). The FMI 08 diagnostic means that the ECM has determined that the signal frequency or the signal pulse width is not within the expected range. The sensor is a PWM sensor that operates at a frequency of approximately 500 hertz. The sensor has an operating duty cycle of 5% to 95%. 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. This is unlikely.Before performing this procedure, inspect the harness connectors that are involved in the circuit. Poor connections can often be the cause of a problem in an electrical circuit. Verify that all connections in the circuit are clean, secure and in good condition. If a problem with a connection is found, correct the problem and verify that this diagnostic code is active before performing this procedure.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 1079 FMI 08 is active before performing this procedure.Note: Use a Digital Multimeter for the measurements in this procedure. System Response:A level 1 warning will be generated. The feature is disabled.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 contact 1 (wire 709-OR) for the voltage supply.
At the back of the harness connector for the sensor, insert a 7X-1710 Multimeter Probe along contact 2 (wire J764-BR) for the ground.
Turn the key start switch and the disconnect switch to the ON position.
Measure the voltage from contact 1 (wire 709-OR) to contact 2 (wire J764-BR).Expected Result:The voltage is 10 0.5 DCV.Results:
