Trouble Diagnosis For Intermittent Incident: Description
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 Intermittent Incidents occurrences 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.
| STEP in Work Flow | Situation |
|---|---|

| 10 | The Diagnostic Procedure for PXXXX does not indicate the malfunctioning area. |
