Introduction
NLEC1367
The engine has an ECM to control major systems such as fuel
control, ignition control, idle air control system, etc. The ECM
accepts input signals from sensors and instantly drives actuators.
It is essential that both input and output signals are proper and
stable. At the same time, it is important that there are no problems
such as vacuum leaks, fouled spark plugs, or other problems with
the engine.
It is much more difficult to diagnose a problem that occurs intermit-
tently rather than continuously. Most intermittent problems are
caused by poor electric connections or improper wiring. In this
case, careful checking of suspected circuits may help prevent the
replacement of good parts.
A visual check only may not find the cause of the problems. A road
test with CONSULT-II (or GST) or a circuit tester connected should
be performed. Follow the “Work Flow” on EC-621.
Before undertaking actual checks, take a few minutes to talk with
a customer who approaches with a driveability complaint. The cus-
tomer can supply good information about such problems, espe-
cially intermittent ones. Find out what symptoms are present and
under what conditions they occur. A “Diagnostic Worksheet” like the
example on next page should be used.
Start your diagnosis by looking for “conventional” problems first.
This will help troubleshoot driveability problems on an electronically
controlled engine vehicle.
SEF907L
DIAGNOSTIC WORKSHEET
NLEC1367S01
There are many operating conditions that lead to the malfunction
of engine components. A good grasp of such conditions can make
trouble-shooting faster and more accurate.
In general, each customer feels differently about a problem. It is
important to fully understand the symptoms or conditions for a
customer complaint.
Utilize a diagnostic worksheet like the one on the next page in order
to organize all the information for troubleshooting.
Some conditions may cause the malfunction indicator lamp to
come on steady or blink and DTC to be detected.
Example:
Vehicle ran out of fuel, which caused the engine to misfire.

STEP
DESCRIPTION
STEP I
Get detailed information about the conditions and the environment when the incident/symptom occurred using
the “DIAGNOSTIC WORK SHEET”, EC-620.
STEP II
Before confirming the concern, check and write down (print out using CONSULT-II or GST) the (1st trip) DTC
and the (1st trip) freeze frame data, then erase the DTC and the data. (Refer to EC-594, EC-596.) The (1st trip)
DTC and the (1st trip) freeze frame data can be used when duplicating the incident at STEP III & IV.
If the incident cannot be verified, perform “TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT”, EC-670.
Study the relationship between the cause, specified by (1st trip) DTC, and the symptom described by the cus-
tomer. (The “Symptom Matrix Chart” will be useful. See EC-648.)
Also check related service bulletins for information.
STEP III
Try to confirm the symptom and under what conditions the incident occurs.
The “DIAGNOSTIC WORK SHEET” and the freeze frame data are useful to verify the incident. Connect CON-
SULT-II to the vehicle in DATA MONITOR (AUTO TRIG) mode and check real time diagnosis results.
If the incident cannot be verified, perform “TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT”, EC-670.
If the malfunction code is detected, skip STEP IV and perform STEP V.
STEP IV
Try to detect the (1st trip) DTC by driving in (or performing) the “DTC Confirmation Procedure”. Check and read
the (1st trip) DTC and (1st trip) freeze frame data by using CONSULT-II or GST.
During the (1st trip) DTC verification, be sure to connect CONSULT-II to the vehicle in DATA MONITOR (AUTO
TRIG) mode and check real time diagnosis results.
If the incident cannot be verified, perform “TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT”, EC-670.
In case the “DTC Confirmation Procedure” is not available, perform the “Overall Function Check” instead. The
(1st trip) DTC cannot be displayed by this check, however, this simplified “check” is an effective alternative.
The “NG” result of the “Overall Function Check” is the same as the (1st trip) DTC detection.
STEP V
Take the appropriate action based on the results of STEP I through IV.
If the malfunction code is indicated, proceed to TROUBLE DIAGNOSIS FOR DTC PXXXX.
If the normal code is indicated, proceed refer to “BASIC INSPECTION”, EC-623. If CONSULT-II is available, per-
form “DATA MONITOR (SPEC)” mode with CONSULT-II and proceed to the “TROUBLE DIAGNOSIS-SPECIFI-
CATION VALUE”, EC-666. (If malfunction is detected, proceed to “REPAIR/REPLACE”. Then perform inspections
according to the Symptom Matrix Chart. (Refer to EC-648.)
STEP VI
Identify where to begin diagnosis based on the relationship study between symptom and possible causes.
Inspect the system for mechanical binding, loose connectors or wiring damage using (tracing) “Harness Layouts”.
Gently shake the related connectors, components or wiring harness with CONSULT-II set in “DATA MONITOR
(AUTO TRIG)” mode.
Check the voltage of the related ECM terminals or monitor the output data from the related sensors with CON-
SULT-II. Refer to EC-657.
The “Diagnostic Procedure” in EC section contains a description based on open circuit inspection. A short circuit
inspection is also required for the circuit check in the Diagnostic Procedure. For details, refer to GI section
(“HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT”, “Circuit Inspection”).
Repair or replace the malfunction parts.
If malfunctioning part cannot be detected, perform “TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT”,
EC-670.
STEP VII
Once you have repaired the circuit or replaced a component, you need to run the engine in the same conditions
and circumstances which resulted in the customer’s initial complaint.
Perform the “DTC Confirmation Procedure” and confirm the normal code [DTC No. P0000] is detected. If the
incident is still detected in the final check, perform STEP VI by using a different method from the previous one.
Before returning the vehicle to the customer, be sure to erase the unnecessary (already fixed) (1st trip) DTC in
ECM and TCM (Transmission control module). (Refer to EC-594, EC-596.)
