TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENTPFP:00006
DescriptionEBS0117J
Intermittent incidents may occur. In many cases, the incident 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 com-
plaint often do not recur on (1st/2nd 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.
COMMON INTERMITTENT INCIDENTS REPORT SITUATIONS
Diagnostic ProcedureEBS0117K
1. INSPECTION START
Erase (1st/2nd trip) DTCs. Refer to EC-999, "
HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFOR-
MATION" .
>> GO TO 2.
2. CHECK GROUND TERMINALS
Check ground terminals for corroding or loose connection.
Refer to EC-1055, "
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”.
III The symptom described by the customer does not recur.
IV (1st/2nd trip) DTC does not appear during the DTC Confirmation Procedure.
VI The Diagnostic Procedure for XXXX does not indicate the malfunctioning area.
