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 sy mptom 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 intermit
tent trouble is easy to
occur (e.g., wire harness, connector, etc.), referring to
“Intermittent and Poor Connec tion 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 re lated to the DTC, clear the DTC once,
perform DTC confirmation procedure and confirm that no
DTC is indicated.
Malfunction Indicator Lamp (MIL) CheckS7RS0B1104002
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 “MIL 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 CheckS7RS0B1104003
NOTE
• There are two types of OBD system depending on the vehicle specification.
For details, refer to “Precaution on On-
Board Diagnostic (OBD) System”.
• 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 th e DTC to the scan
tool.
Therefore, check both of the ECM and TCM
for any DTC with the SUZUKI 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.

Using Scan Tool
1) Prepare OBD generic scan tool or SUZUKI scan tool.
2) With ignition switch turned OFF, connect it to DLC (1) located on underside of instrument panel at
driver’s seat side.
Special tool
(A): SUZUKI scan tool
3) Turn ignition switch ON and confirm that MIL lights.
4) Read DTC, pending 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 further details.
If communication between scan tool and ECM is not
possible, check if scan tool is communicable by
connecting it to ECM in another vehicle. If
communication is possible in this case, scan tool is
in good condition. Then check data link connector
and serial data line (circuit) in the vehicle with which
communication was not possible. If connector and
circuit are OK, check that power supply and ground
circuits of ECM and DLC are in good condition
referring to “ECM Power and Ground Circuit Check”. 5) After completing the check,
turn ignition switch OFF
and disconnect scan tool from data link connector.
Without Using Scan Tool (Hong Kong Model) 1) Turn ignition switch to OFF position.
2) Using service wire, ground diagnosis switch terminal (1) of diagnosis connector (2).
3) Turn ON ignition switch and check DTC displayed on
odometer (3) of combination meter.
When more than 2 DTCs are stored in memory,
blinking for each DTC star ts with the smallest DTC
number in increasing order. Also, DTC is indicated
repeatedly until the ignition switch is turned OFF or
disconnect service wire.
NOTE
When no DTC is detected, display on
odometer of combinatio n meter is “0000”.

4) After completing the check, turn ignition switch to
OFF position and disconnect service wire from
diagnosis connector.

DTC ClearanceS7RS0B1104004
NOTE
There are two types of OBD system
depending on the vehicle specification.
For details, refer to “Precaution on On-Board
Diagnostic (OBD) System”.

Using Scan Tool1) Connect OBD generic scan to ol or SUZUKI 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. Refer to scan
tool operator’s manual for further details.
4) After completing the clear ance, 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”.)

Without Using Scan Tool (Hong Kong Model)
1) Turn ignition switch to OFF position.
2) Disconnect battery negative cable for specified time below to erase diagnostic trouble code stored in
ECM memory and reconnect it.

Scan Tool DataS7RS0B1104007
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 re ference 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 details, refer to “Precaution on On-Board Diagnostic (OBD) System”.
• With the 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 O FF A/C (if equipped with A/C), all electric loads, P/S and all the other
necessary switches.
