Parts of the Event Code
Event Code – “E” identifies the code as an event
code. “XXX(X)” represents a numeric identifier for the
event code. The fourth “(X)” assigns one of three
levels to the active event code according to the
severity of the abnormal system condition. Next is a
code description. Refer to the following example:
• E360(1) Low Oil Pressure
• E360(2) Low Oil Pressure
• E360(3) Low Oil Pressure
The definition for the levels of severity for an event
are defined below:
Level 1 – Level 1 alerts the operator that an engine
system requires attention. The operator should check
that the involved system condition or the operator
should perform maintenance on the involved system
at the earliest possible time.
Level 2 – Level 2 requires a change in the operation
of the engine or the performance of a maintenance
procedure. Failure to correct the problem that caused
this warning may result in damaged the engine
components.
Level 3 – Level 3 requires an immediate safe
shutdown of the engine to avoid damage to the
engine or injury to personnel around the engine. The
problem that caused the event must be corrected
before engine operation can resume.
Active Event Codes
An active event code represents a problem with
engine operation. Correct the problem as soon as
possible.
Active event codes are listed in ascending numerical
order. The code with the lowest number is listed first.
Illustration 25 is an example of the operating range of
a sensor.
Illustration 25 g01365757
Example of the typical operating range of a sensor
(1) This area represents the normal operating range of the engine
parameter.
(2) In these areas, the engine is operating in an unsafe operating
range of the monitored parameter. An event code will be
generated for the monitored parameter. The sensor circuit
does not have an electronic problem.
(3) In these areas, the signal from the sensor is outside of the
operating range of the sensor. The sensor circuit has an
electronic problem. A diagnostic code will be generated for the
sensor circuit. Refer to Troubleshooting, “Diagnostic Trouble
Codes” for additional information on diagnostic codes.
Logged Event Codes
When the Electronic Control Module (ECM)
generates an event code, the ECM logs the code in
permanent memory. The ECM has an internal
diagnostic clock. The ECM will record the following
information when an event code is generated:
• The hour of the first occurrence of the code
• The hour of the last occurrence of the code
• The number of occurrences of the code
Logged events are listed in chronological order. The
most recent event code is listed first.
