EXPLANATION OF COLUMNS
0006
The columns in the troubleshooting table are defined as follows:
a. MALFUNCTION. For symptom- or condition-based troubleshooting, this is a visual or operational
indication that something is wrong with the equipment.
b. CID FMI Code. For diagnostic code-based troubleshooting, the Component Identifier (CID) is a four-digit
number assigned to each monitored component connected to an electronic control module (ECM): e.g.,
0174 represents the fuel temperature sensor. The Failure Mode Identifier (FMI) is a two-digit number that
represents a specific type of failure: e.g., 04 indicates that the ECM detects a voltage below normal condi-
tion on a monitored circuit. Together, the numbers display as 0174-04 Fuel Temperature Short to Ground.
c.
EID FMI Code. An Event Identifier (EID) code is a four-character code that is assigned to a specific
abnormal engine or machine operating condition. The first character in an event code is the letter "E," while
the second, third, and fourth characters are numeric: e.g., E539 High Intake Manifold Air Temperature.
A fifth digit separated by a hyphen at the end of the code identifies if the event is (1) a warning, (2) a
derate, or (3) a shutdown: e.g., E360-1 Low Oil Pressure Warning. A warning indicates that the condition is
serious but will not cause a derate or a shutdown. For a derate condition, the ECM reduces engine power
to prevent possible engine damage. For a shutdown condition, the ECM actuates an audible and visible
alarm to warn the operator that engine damage is occurring. This alarm notifies the operator to shut down
the engine.
d. TEST OR INSPECTION. A procedure to isolate the problem in a system or component.
e. CORRECTIVE ACTION. A procedure to correct the problem.
