Step 2: DTC / Freeze Frame Data Check, Record and
Clearance
First, check DTC (including pending DTC), referring to
“DTC Check”. If DTC is indicated, print it and freeze
frame data or write them down and then clear them by
referring to “DTC Clearance”. DTC indicates malfunction
that occurred in the system but does not indicate
whether it exists now or it occurred in the past and the
normal condition has been restored now. To check which
case applies, check the symptom in question according
to Step 5 and recheck DTC according to Step 6 and 7.
Attempt to diagnose a trouble based on DTC in this step
only or failure to clear the DTC in this step will lead to
incorrect diagnosis, trouble diagnosis of a normal circuit
or difficulty in troubleshooting.
Step 3 and 4: Visual Inspection
As a preliminary step, be sure to perform visual check of
the items that support proper function of the engine
referring to “Visual Inspection”.
Step 5: Trouble Symptom Confirmation
Based on information obtained in “Step 1: Customer
Complaint Analysis: ” and “Step 2: DTC / Freeze Frame
Data Check, Record and Clearance: ”, confirm trouble
symptoms. Also, reconfirm DTC according to “DTC
Confirmation Procedure” described in each DTC diag.
flow.
Step 6 and 7: Rechecking and Record of DTC /
Freeze Frame Data
Refer to “DTC Check” for checking procedure.
Step 8: Engine Basic Inspection and Engine
Symptom Diagnosis
Perform basic engine check according to “Engine Basic
Inspection” first. When the end of the flow has been
reached, check the parts of the system suspected as a
possible cause referring to “Engine Symptom Diagnosis”
and based on symptoms appearing on the vehicle
(symptoms obtained through steps of customer
complaint analysis, trouble symptom confirmation and/or
basic engine check) and repair or replace faulty parts, if
any.
Step 9: Troubleshooting for DTC (See each DTC
Diag. Flow)
Based on the DTC indicated in Step 6 or 7 and referring
to the applicable DTC diag. flow, locate the cause of the
trouble, namely in a sensor, switch, wire harness,
connector, actuator, ECM or other part and repair or
replace faulty parts.Step 10: Intermittent Problems Check
Check parts where an intermittent trouble is easy to
occur (e.g., wire harness, connector, etc.), referring to
“Intermittent and Poor Connection Inspection in Section
00” and related circuit of DTC recorded in Step 2.
Step 11: Final Confirmation Test
Confirm that the problem symptom has gone and the
engine is free from any abnormal conditions. If what has
been repaired is related to the DTC, clear the DTC once,
perform DTC confirmation procedure and confirm that no
DTC is indicated.
Malfunction Indicator Lamp (MIL) CheckS6RW0D1104002
1) Turn ON ignition switch (with engine at stop) and
check that MIL (1) lights.
If MIL does not light up (or MIL dims) but engine can
be starting, go to “Malfunction Indicator Lamp Does
Not Come ON with Ignition Switch ON and Engine
Stop (but Engine Can Be Started)” for
troubleshooting.
If MIL does not light with ignition switch ON and
engine does not start though it is cranked up, go to
“ECM Power and Ground Circuit Check”.
2) Start engine and check that MIL turns OFF.
If MIL remains ON and no DTC is stored in ECM, go
to “Malfunction Indicator Lamp Remains ON after
Engine Starts” for troubleshooting.
DTC CheckS6RW0D1104085
NOTE
• There are two types of OBD system
depending on the vehicle specification.
For identification, refer to “Precaution on
On-Board Diagnostic (OBD) System”.

I4RS0A110012-01

Downloaded from www.Manualslib.com manuals search engine 1A-26 Engine General Information and Diagnosis:
• The MIL is turned on when the ECM and/or
TCM detect malfunction(s). Each ECM and
TCM stores diagnostic information as the
diagnostic trouble code (DTC) in its
memory and outputs the DTC to the scan
tool.
Therefore, check both of the ECM and TCM
for any DTC with the scan tool because the
DTC stored in ECM and TCM is not read
and displayed at a time. However, each of
the ECM and TCM needs not to be checked
with the generic scan tool because the
DTC stored in ECM and TCM is read and
displayed at a time.

1) Prepare CAN communication OBD generic scan tool
or SUZUKI scan tool.
Special tool
(A): SUZUKI scan tool (SUZUKI-SDT)
2) With ignition switch OFF, connect it to DLC (1)
located on underside of instrument panel at driver’s
seat side.
3) Turn ignition switch ON and confirm that MIL lights.
4) Read DTC and freeze frame data according to
instructions displayed on scan tool and print them or
write them down. Refer to scan tool operator’s
manual for details.
If communication between scan tool and ECM is not
possible, go to “Troubleshooting for Communication
Error with Scan Tool Using CAN”.
5) After completing the check, turn ignition switch off
and disconnect scan tool from DLC.
DTC ClearanceS6RW0D1104004
NOTE
There are two types of OBD system
depending on the vehicle specification.
For identification, refer to “Precaution on On-
Board Diagnostic (OBD) System”.

1) Connect SUZUKI scan tool or CAN communication
OBD generic scan tool to data link connector in the
same manner as when making this connection for
DTC check.2) Turn ignition switch OFF and then ON.
3) Erase DTC and pending DTC according to
instructions displayed on scan tool. Freeze frame
data is cleared with the DTC. Refer to scan tool
operator’s manual for further details.
If communication between scan tool and ECM is not
possible, go to “Troubleshooting for Communication
Error with Scan Tool Using CAN”.
4) After completing the clearance, turn ignition switch
OFF and disconnect scan tool from data link
connector.
NOTE
DTC and freeze frame data stored in ECM
memory are also cleared in the following
cases. Be careful not to clear them before
keeping their record.
• When power to ECM is cut off (by
disconnecting battery cable, removing
fuse or disconnecting ECM connectors).
• When the same malfunction (DTC) is not
detected again during 40 engine warm-up
cycles. (See “Warm-Up Cycle” of “On-
Board Diagnostic System Description”.)

Troubleshooting for Communication Error with
Scan Tool Using CAN
S6RW0D1104083
Perform this troubleshooting when it is not possible to
communicate between scan tool and ECM/TCM.
NOTE
• When performing this troubleshooting, be
sure to have full understanding of
“Precaution on CAN Troubleshooting” and
observe it.
• It may be possible that CAN system has
trouble because of fuse blown or low
battery voltage. Before troubleshooting,
check to make sure that fuse, battery
voltage and generator status are normal.
• When disconnecting each control module
connector in this troubleshooting, various
DTCs will be detected. Be sure to clear
DTCs in the following control modules
after completing this troubleshooting.
–ECM
–BCM
–TCM
– Keyless start control module
– 4WD control module
– HVAC control module (Auto A/C model)
– P/S control module

Scan Tool DataS6RW0D1104007
As the data values are standard values estimated on the basis of values obtained from the normally operating vehicles
by using a scan tool, use them as reference values. Even when the vehicle is in good condition, there may be cases
where the checked value does not fall within each specified data range. Therefore, judgment as abnormal should not
be made by checking with these data alone.
Also, conditions that can be checked by the scan tool are those detected by ECM and output from ECM as commands
and there may be cases where the engine or actuator is not operating (in the condition) as indicated by the scan tool.
Be sure to use the timing light to check the ignition timing.
NOTE
• There are two types of OBD system depending on the vehicle specification.
For identification, refer to “Precaution on On-Board Diagnostic (OBD) System”.
• With the CAN communication generic scan tool, only star (*) marked data in the following table can
be read.
• When checking the data with the engine running at idle or racing, be sure to shift M/T gear to the
neutral position and A/T gear to the “Park” position and pull the parking brake fully. Also, if nothing
or “no load” is indicated, turn OFF A/C (if equipped with A/C), all electric loads, P/S and all the other
necessary switches.
