TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT
TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT PFP:00006
Description EBS010XK
Intermittent incidents (I/I) 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.
Common I/I Report Situations
Diagnostic Procedure EBS010XL
1. INSPECTION START
Erase (1st trip) DTCs. Refer to EC-514, "
HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMA-
TION" .
>> GO TO 2.
2. CHECK GROUND TERMINALS
Check ground terminals for corroding or loose connection.
Refer to GI-23, "
How to Perform Efficient Diagnosis for an Electrical Incident" , “Incident Simulation Tests”,
“Ground Inspection”.
OK or NG
OK >> GO TO 3.
NG >> Repair or replace.
3. SEARCH FOR ELECTRICAL INCIDENT
Perform GI-23, "
How to Perform Efficient Diagnosis for an Electrical Incident" , “Incident Simulation Tests”.
OK or NG
OK >> INSPECTION END
NG >> Repair or replace.
STEP in Work Flow Situation
II The CONSULT-II is used. The SELF-DIAG RESULTS screen shows time data other than [0] or [1t].
III The symptom described by the customer does not recur.
IV (1st trip) DTC does not appear during the DTC Confirmation Procedure.
VI The Diagnostic Procedure for PXXXX does not indicate the malfunctioning area.
