Intermittent Failures

Intermittent failures may cause malfunction light to flicker on-and-off. Light goes out after intermittent fault goes away. The corresponding trouble code may be retained in control unit memory, depending on the system.

If related fault does not reoccur within a certain time frame, related trouble code will be erased from control unit memory. Intermittent failures may be caused by sensor, connector or wiring related problems. See INTERMITTENTS in TESTS W/O CODES article.
