Intermittent Conditions

An intermittent problem may or may not set a diagnostic trouble code. If it is an intermittent problem, a diagnostic trouble code chart is not used. Consult Diagnostic Aids that correspond to the intermittent diagnostic trouble code.

Also, refer to symptoms. A physical/visual inspection of the applicable sub-system most often will resolve the problem. Use of the customer snap-shot and Scan tool snap-shot may isolate the malfunction.
