SECTION 2
2.17 ENGINE CONTROL MODULE,
FUNCTIONAL DESCRIPTION
Diagnostic Fault Codes are provided to indicate an
electrical or electronic problem has been detected by
the ECM (Engine Control Module). In some cases, the
engine performance can be affected when the
condition causing the code exists. More frequently,
however, the operator cannot detect any difference in
the engine performance.
The controller indicates an engine performance
problem has occurred whenever the Engine Warning
Lamp is flashing. The diagnostic code may indicate the
cause of the problem, and should be corrected.
If the controller does not indicate a problem with the
engine performance, but a diagnostic code is logged by
the ECM, an abnormal condition was detected that did
not affect performance.

If this is the case, unless there are several occurrences
of the code in a very short period of time, or, the ECM
is indicating an Active Code at the present time, there
is most likely nothing wrong with the system.
If there is an error the controller should display a brief
message containing the Failure Mode Indicator (FMI)
and Suspect Parameter Number (SPN) in the LCD of
the master gauge. This message helps to pinpoint the
source of the problem and aid in troubleshooting the
compressor.
NOTE
Only active diagnostic codes can be read in this
manner. Logged diagnostic codes must be
retrieved with an Electronic Service Tool.
Refer to Table 2-1
performance of active diagnostic codes.
