TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT

TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT

PFP:00006

Description

ABS002E2

Intermittent incidents may occur. In many cases, the malfunction resolves itself (the part or circuit function
returns to normal without intervention). It is important to realize that the symptoms described in the customer's
complaint often do not recur on (1st trip) DTC visits. Realize also that the most frequent cause of I/I occur-
rences is poor electrical connections. Because of this, the conditions under which the incident occurred may
not be clear. Therefore, circuit checks made as part of the standard diagnostic procedure may not indicate the
specific malfunctioning area.
