Intermittent Malfunction Indicator Lamp (MIL)

In the case of an intermittent fault the MIL may illuminate, and then after three trips go OFF. However, the corresponding diagnostic trouble code will store in the memory. When unexpected diagnostic trouble codes appear, check for an intermittent malfunction.

A diagnostic trouble code may reset. Consult the Diagnostic Aids that associate with the diagnostic trouble code. A physical inspection of the applicable sub-system will most often resolve the problem.
