INTERMITTENT PROBLEMS AND MALFUNCTION INDICATOR LAMP
In the case of an intermittent problem, the Malfunction Indicator Lamp will light for ten
seconds and then will go out. However, the corresponding code will be stored in the memory
of the ECM. When unexpected codes appear during the code reading process, one can
assume that these codes were set by an intermittent malfunction and could be helpful in
diagnosing the system.
An intermittent code may or may not reset. IF IT IS AN INTERMITTENT FAILURE, A
DIAGNOSTIC CODE CHART IS NOT USED. Consult the Diagnostic Help section following
the Circuit Description information. Troubleshooting also covers the topic of Intermittents.
A physical inspection of the applicable sub-system most often will resolve the problem.
