The FMI 08 means that the ECM has determined that the signal frequency or the signal pulse width is not within the expected range. This diagnostic code is associated with the pressure sensor (override). Power to the transmission ecm is low and that is what logged the code 079 168.04. The monitor sends power to the alternator to turn it on but, no voltage code is on the monitor. Check voltage at the batteries and from the alternator. This would cause the lightning bolt symbol to stay or come on.
This is triggered when the engine has been cranked hard and the battery voltage is low. The light bulb could be loose,missing or burnt out.įMI 04 Voltage that is below normal or shorted low FMI 05 most often relates to a driver circuit. FMI 05 occurs when the current through the identified circuit is below the valid range. MID means module identifier, 030 is the monitor.ĬID is the component identifier, 324 is the action lamp (the big red warning light)įMI is failure mode identifier, 05 is "Current below normal". There may be delays in between posts due to interruptions here so no need to stand by live. An electronic control module which uses the CAT data link has failed. The circuit for the CAT data link in the machine harness is open. The circuit for the CAT data link in the machine harness is shorted to the +battery. The causes are listed in order of probability: Poor electrical connection at a machine harness connector The circuit for the CAT data link in the machine harness is shorted to ground.
The possible causes of this diagnostic code are listed below. The information from the CAT data link indicates the abnormal values in the readout. The information from the actual gear status is not being received from other electronic control modules through the CAT data link. The following example shows a possible diagnostic code. This diagnostic code is recorded when the main display module does not receive expected information. The 030 is the MID (Module Identifier) for the monitor ECM, the 248 is the CID (Component Identifier) for the display panel data link, and the 02 is the FMI (Failure Mode Identifier) for an intermittent or erratic problem.
