Any monitored item that does not match the vehicle being diagnosed is deleted from the display automatically.
*: This signal is converted by ECM internally. Thus, it differs from ECM terminal voltage.
Major Sensor Reference Graph in Data Monitor Mode
EBS013JU
The following are the major sensor reference graphs in “DATA MONITOR” mode.
ACCEL POS SEN, “CKPS·RPM (TDC)”, “MAS AIR/FL SE”
Below is the data for “ACCEL POS SEN”, “CKPS·RPM (TDC)” and “MAS AIR/FL SE” when revving engine
quickly up to 3,000 rpm under no load after warming up engine to the normal operating temperature.

TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT
PFP:00006
Description
EBS013JV
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
EBS013JW
1.
INSPECTION START
Erase (1st/2nd trip) DTCs. Refer to
EC-34, "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-24, "How to Perform Efficient Diagnosis 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-24, "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.

ECM Terminals and Reference Value
EBS013JX
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.
