running.
• When it is necessary to run the engine
indoors, make sure that the exhaust gas is
forced outdoors.
• Do not perform service work in areas
where combustible materials can come in
contact with a hot exhaust system. When
working with toxic or flammable materials
(such as gasoline and refrigerant), make
sure that the area you work in is well-
ventilated.
• To avoid getting burned, keep away from
hot metal parts such as the radiator,
exhaust manifold, tail pipe, muffler, etc.
• New and used engine oil can be
hazardous. Children and pets may be
harmed by swallowing new or used oil.
Keep new and used oil and used engine oil
filters away from children and pets.
Continuous contact with used engine oil
has been found to cause [skin] cancer in
laboratory animals. Brief contact with used
oil may irritate skin. To minimize your
exposure to used engine oil, wear a long-
sleeve shirt and moisture-proof gloves
(such as dish washing gloves) when
changing engine oil. If engine oil contacts
your skin, wash thoroughly with soap and
water. Launder any clothing or rags if wet
with oil, recycle or properly dispose of
used oil and filters.
• Be sure to observe following instructions
when handling service materials such as
fuel, oil, fluid, coolant, grease, sealant,
thread lock cement, etc. Otherwise, your

• When checking ECM for DTC, keep in mind that DTC
is displayed on the scan tool as follows depending on
the scan tool used.
– SUZUKI scan tool displays DTC detected by ECM.
– CAN communication OBD generic scan tool
displays DTC detected by each of ECM and TCM
(for A/T model) simultaneously.
• Priorities for diagnosing troubles
If two or more DTCs are stored, proceed to the DTC
flow which has been detected earliest in the order and
follow the instruction in that flow.
If no instructions are given, troubleshoot DTCs
according to the following priorities.
a. DTCs other than DTC P0171 / P0172 (Fuel
system too lean / too rich), DTC P0300 / P0301 /
P0302 / P0303 / P0304 (Misfire detected) and
DTC P0401 / P0402 (EGR flow malfunction)
b. DTC P0171 / P0172 (Fuel system too lean / too
rich) and DTC P0401 / P0402 (EGR flow
malfunction)
c. DTC P0300 / P0301 / P0302 / P0303 / P0304
(Misfire detected)
• Be sure to read “Precautions for Electrical Circuit
Service in Section 00” before inspection and observe
what is written there.
• ECM replacement:
When substituting a known-good ECM, check for the
following conditions. Neglecting this check may cause
damage to a known-good ECM.
– Resistance value of all relays, actuators is as
specified respectively.
– MAP sensor, A/C refrigerant pressure sensor (if
equipped with A/C), accelerator pedal position
(APP) sensor and TP sensor are in good condition
and none of power circuits of these sensors is
shorted to ground.
• Communication of ECM, BCM, combination meter,
keyless start control module (if equipped with keyless
start control system), 4WD control module (if
equipped), TCM (for A/T model) and ABS control
module, is established by CAN (Controller Area
Network). (For more detail of CAN communication for
ECM, refer to “CAN Communication System
Description”). Therefore, handle CAN communication
line with care referring to “Precaution for CAN
Communication System in Section 00”.
• Immobilizer transponder code registration after
replacing ECM (Immobilizer model)
When ECM is replaced with new one or with another
one, make sure to register immobilizer transponder
code to ECM correctly according to “Procedure after
ECM Replacement in Section 10C”.Precautions for DTC TroubleshootingS6RW0D1100003
• Before performed trouble shooting, be sure to read
the “Precautions of ECM Circuit Inspection”.
• When measuring circuit voltage, resistance and/or
pulse signal at ECM connector, connect the special
tool to ECM and/or the ECM connectors referring to
“Inspection of ECM and Its Circuits”.
• Upon completion of inspection and repair work,
perform “DTC Confirmation Procedure” and confirm
that the trouble has been corrected.
Precautions of ECM Circuit InspectionS6RW0D1100004
• ECM connectors are waterproofed. Each terminal of
the ECM connectors is sealed up with the grommet.
Therefore, when measuring circuit voltage, resistance
and/or pulse signal at ECM connector, do not insert
the tester’s probe into the sealed terminal at the
harness side. When measuring circuit voltage,
resistance and/or pulse signal at ECM connector,
connect the special tool to the ECM connectors. And,
insert the tester’s probe into the special tool’s
connectors at the harness side, and then measure
voltage, resistance and/or pulse signal. Or, ECM and
its circuits may be damaged by water.
• Wire colors of the special tool’s connectors are
different from the ones of the ECM connectors.
However, the circuit arrangement of the special tool’s
connectors is same as the one of the ECM
connectors. Therefore, measure circuit voltage and
resistance by identifying the terminal location subject
to the measurement.
Precautions of Electric Throttle Body System

Outline of troubleshooting
When there is a trouble with CAN, perform “Troubleshooting for Communication Error with Scan Tool Using CAN” and/
or “Troubleshooting for CAN-DTC”. Not using this procedure or performing troubleshooting in any other way may skip
some check points resulting in misdiagnosis or take a longer time than necessary.
1) Checking connector related to CAN
2) Checking CAN line
3) Checking each control module/sensor using “DTC check” or “Bus Check”
4) Checking power and ground connection of each control module/sensor
CAN-DTC
Even when DTC related to CAN (= CAN-DTC) as described below is detected, it is not possible to point out the
specific trouble point by CAN-DTC itself. Be sure to troubleshoot according to “Troubleshooting for CAN-DTC”.
CAN-DTC table
Communication with scan tool
• K line or CAN line is used for communication between each control module and scan tool.
Refer to “CAN schematic and routing diagram: ” to determine which line is used for communication between each
control module and scan tool.
• ECM and TCM use CAN line for communication with scan tool. Even if CAN has a trouble other than between DLC
and BCM, communication may also fail between scan tool and these control modules. In such case, perform
troubleshooting according to “Troubleshooting for Communication Error with Scan Tool Using CAN”.
• BCM, ABS control module and 4WD control module use K-line for communication with scan tool. Even if CAN has a
trouble, it is possible to communicate between scan tool and these control modules.
Bus check with SUZUKI scan tool
SUZUKI scan tool (SUZUKI-SDT) efficiently diagnoses a CAN bus malfunction by “Communication Bus Check” and
“Communication Malfunction DTC” under “Bus check”.
“Communication Bus Check” can display all control modules/sensors name communicated by CAN.
Also, “Communication Malfunction DTC” can display only CAN-DTC which is detected by the control modules (ECM
and TCM) communicating with scan tool using CAN line.

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.

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.
