FAQs

Is FMI 5 current below normal or open circuit? ›

The FMI 5 in this example tells us that there is low current (amps) or an open in the circuit. Generally, this type of fault tells us that there is a wire that is broken or disconnected.

The 545 actually is SYS. It means "system." The 160 is the module that is causing issues on the vehicle or creating a collision on the data bus of the vehicle by having abnormal spiking. 160 is assigned to the electrical system, in particular, the alternator.

The Ford EEC or Electronic Engine Control is a series of ECU (or Engine Control Unit) that was designed and built by Ford Motor Company.

Most likely it thinks the DEF tank is empty because you have the 545 25 codes which is the sensor for the level valve in the tank itself. This will also cause you to have the issue wit hteh dpf system when that level sensor is faulting. Have that sensor tested and that level sensor changed out.

Current Below Normal Or Open Circuit: a) A current signal, data or otherwise, is below the predefined limits that bound the range (Region f of the signal range definition). Broadcast of data value is substituted with the “error indicator” value.

An open-circuit fault occurs if a circuit is interrupted by a failure of a current-carrying wire (phase or neutral) or a blown fuse or circuit breaker. In three-phase systems, a fault may involve one or more phases and ground, or may occur only between phases.

Your truck is experiencing a dead throttle, no-start, or internal failure, Check Engine Light is on, the ABS Light staying on, DEF Light staying on, and Instrument Cluster loses communication. Also if CPC reads as a different module (reads as CPC2, TCM, etc.), CPC Hardware Failure Fault Code SPN 609 FMI 12.

Definition. FADEC is a system consisting of a digital computer, called an electronic engine controller (EEC) or engine control unit (ECU), and its related accessories that control all aspects of aircraft engine performance.

If your DEF got low, it will throw a EEC61, but you need to fill the DEF tank 1/2 full or more. After you drive awhile, after 3 key cycles that light should go off. IF THIS IS THE PROBLEM. If you do not fill it up, the Engine will Derate to 25%, then if you continue to drive, it will derate you to 5 miles per hour.

cab 33 is dash code for a system fault the dash will display a number for faults in a system on a truck code 33 happens to be for the SAM Chasis moudule, the dash code does not go into depth on what is wrong in the system that is where you would need a shop to scan the truck with scan tool.

What is Freightliner code SPN 521052 FMI 31? ›

SPN 521052/FMI 31

Description This Code Sets When SPN 521050/FMI 31 has been Present for One Hour of Idle Time, the Vehicle has been Restarted or Six Gallons of Fuel has been Used.

SPN 96 /FMI 19

Description This fault indicates a fuel level error signal at the Common Powertrain Controller (CPC). Check as follows: NOTE: Fuel level sensor is hardwired to instrument cluster. Fuel level signal is multiplexed from instrument cluster to the CPC.

SPN 111/FMI 4

Description This Fault Sets when the Common Powertrain Controller (CPC) Detects that there is a Short to Ground on the Coolant Level Circuit or the Engine Coolant Level is Low.

In an electric power system, overcurrent or excess current is a situation where a larger than intended electric current exists through a conductor, leading to excessive generation of heat, and the risk of fire or damage to equipment.

Failure Mode Indication (FMI), as part of the J1939 standard used in heavy-duty vehicles, functions by closely monitoring system components. When a fault occurs, FMI generates a precise code that identifies the specific nature of the issue, much like an advanced version of a 'check engine' light.

Page 1. Failure Mode Identifier (FMI) Codes on J1939 data link. The FMI is used along with the SPN to provide specific information that relates to a diagnostic trouble code (DTC). The FMI may indicate that a problem with an electronic circuit or an electronic component has been detected.

Failure Mode Identifiers (FMI) are used to communicate what the ECU has detected, not the root cause of the problem. For example 100-03 “Engine Oil Pressure: Voltage above normal”. The system detected that the signal voltage from this sensor input went above the valid voltage range.
