TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT
TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT
PFP:00006
Description
EBS0138J
Intermittent incidents (I/I) 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
complaint often do not recur on (1st/2nd 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
EBS0138K
1.
INSPECTION START
Erase (1st/2nd trip) DTCs. Refer to
EC-961, "HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFOR-
.
>> GO TO 2.
2.
CHECK GROUND TERMINALS
Check ground terminals for corroding or loose connection.
Refer to GI-21, “HOW TO PERFORM EFFICIENT DIAGNOSES FOR AN ELECTRICAL INCIDENT”, “Circuit
Inspection”, “GROUND INSPECTION”.
OK or NG
OK
>> GO TO 3.
NG
>> Repair or replace.
3.
SEARCH FOR ELECTRICAL INCIDENT
Perform GI-21, “HOW TO PERFORM EFFICIENT DIAGNOSES 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.

ECM Terminals and Reference Value
EBS0138L
Remarks: Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

1.
INSPECTION START
Start engine.
Is engine running?
Yes or No
Yes
>> GO TO 7.
No
>> GO TO 2.
2.
CHECK ECM POWER SUPPLY CIRCUIT-I
1.
Turn ignition switch OFF, wait at least 10 seconds and then turn ON.
2.
Check voltage between ECM terminals 107, 108 and ground
with CONSULT-II or tester.
OK or NG
OK
>> GO TO 4.
NG
>> GO TO 3.
3.
DETECT MALFUNCTIONING PART
Check the following.
●
Fuse block (J/B) connector M1
●
10A fuse
●
Harness for open or short between ECM and fuse
>> Repair open circuit or short to ground or short to power in harness or connectors.
4.
CHECK GROUND CONNECTIONS
1.
Turn ignition switch OFF.
2.
Loosen and retighten body ground screw. Refer to
.
OK or NG
OK
>> GO TO 5.
NG
>> Repair or replace ground connection.
