g. Perform the test or inspection, observe the outcome, and perform the corrective action in the order listed
until the malfunction/CID FMI Code is corrected. When troubleshooting identifies a repair as a corrective
action, perform the repair, then return to troubleshooting to verify the malfunction is resolved and, if neces-
sary, continue troubleshooting. Do not perform any maintenance task unless the troubleshooting proce-
dure instructs you to do so.
EXPLANATION OF COLUMNS
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 code displays as 0174-04 Fuel Temperature Short to Ground.
EID FMI (EVENT) CODE. An event code is a four-digit code that is assigned to a specific abnormal engine
or machine operating condition. The first digit in an event code is the letter "E," while the second, third, and
fourth digits are numeric. (e.g. E539 High Intake Manifold Air Temperature). A separate fifth digit at the end
of the code identifies if the event is a warning (1), a derate (2), or a shutdown (3) (e.g., E360-1 Low Oil
Pressure Warning). A warning indicates that the condition is serious, but will not cause a derate or a shut-
down. 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 dam-
age 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.
