14 Special Instruction Detailed FMI Explanation
FMI 00 Data Valid But Above Normal Operating Range - Every electronic control system has a high limit setting for the expected signal operating range. The high limit includes over range signals. A sensor that is still operating, but sending a signal above the expected limit will cause an FMI 00 to be recorded.Following are some FMI 00 causes:
Signal above normal range
Signal shorted to the +battery circuit
Sensor out of calibration Following is an example of a sensor that needs calibration:
A PWM signal with an 80% duty cycle is a valid signal. If the PWM signal exceeds 80%, the sensor is still working, but the signal from the sensor is above range.FMI 01 Data Valid But Below Normal Operating Range - Every electronic control system sets a low limit for the expected signal operating range. A sensor may still be working, but is sending a signal below the minimum range.Following are some FMI 01 causes:
Signal below normal range
Improper timing Following is an example of a PWM sensor:
This sensor is not expected to generate a PWM signal below a duty cycle of 5% with 0 psi air pressure. A sensor that generates a signal with a duty cycle of 4% at 0 psi will work, but the signal is below range. FMI 01 will be recorded for this condition.FMI 02 Data Erratic, Intermittent or Incorrect - A signal from a component is present. The ECM that reads the diagnostic information cannot read the signal properly. The signal appears to be unstable, or invalid. The data can be intermittent. This condition can relate to communication between controls. Following are some FMI 02 causes:
Failed connection
Intermittent or erratic signal
Changed software
Noisy signal
Out of range signal FMI 03 Voltage Above Normal or Shorted High - A component or system voltage is higher than the limit. FMI 03 most often relates to a signal circuit.Following are some FMI 03 causes:
Failed sensor with high voltage output
Harness with a sensor signal wire shorted to high voltage
Harness with an open circuit in the sensor signal wire causing the signal to go high
Failed ECMNote: High voltage is any voltage that is greater than the sensor
