WARNING!
• When performing a road test, select a place where there is no traffic or possibility of a traffic
accident and be very careful during testing to avoid occurrence of an accident.
• Road test should be carried out by 2 persons, a driver and a tester, on a level road.
NOTE
Check to make sure that following conditions are satisfied when using this “DTC Confirmation
Procedure”.
• Intake air temperature at engine start: –10 °C (14 °F) to 80 °C (176 °F)
• Intake air temperature: –10 °C (14 °F) to 70 °C (158 °F)
• Engine coolant temperature: 70 °C (158 °F) or more
• Altitude (barometric pressure): 2500 m, 8200 ft or less (560 mmHg, 74.4 kPa or more)
1) With ignition switch turned OFF, connect scan tool.
2) Turn ON ignition switch and clear DTC using scan tool.
3) Start engine and warm up to normal operating temperature.
4) Drive vehicle at 40 mph (60 km/h) or higher. (engine speed: 2500 – 3000 r/min.)
5) Keep above vehicle speed for 6 min. or more. (Throttle valve opening is kept constant in this step.)
6) Release accelerator pedal and with engine brake applied, keep vehicle coasting (with fuel cut for 3 sec. or more)
and then stop vehicle.

DTC Troubleshooting
NOTE
If the vehicle runs under fuel deficient condition (such as a condition in which the fuel pump is unable
to draw fuel properly), DTC of misfire may possibly be detected due to fuel pressure drop even though
there is no abnormal condition existing in the Engine and Emission System.
Therefore, if the DTC still cannot be detected with “Trouble Symptom Confirmation” executed in
accordance with “Engine and Emission Control System Check” the possible cause may be due to a
running condition under insufficient fuel supply at the time of detecting DTC of misfire.
Step Action Yes No

Section 1H” and “Ignition Spark Test in Section 1H”.
Are they in good condition?Go to Step 5. Faulty ignition coil, wire
harness, spark plug or
other system parts.
5Fuel injector circuit check
1) Using sound scope, check each injector operating sound
at engine cranking or idling.

Input / Output Signal Table of 4WD Control ModuleS6RW0D3201008
4WD control module outputs the following signals to coupling assembly, indicators, according to the 2WD/4WD switch
operation.
On-Board Diagnostic System DescriptionS6RW0D3201009
For 4WD control system, 4WD control module has the following functions.
• When ignition switch is turned ON with engine at stop, 4WD AUTO indicator (1) and 4WD LOCK indicator (2) turn
on at the same time for 2 seconds in order to check operation of these indicators.
• When 4WD control module detects any malfunction in the following area, 4WD AUTO indicator (1) and 4WD LOCK
indicator (2) flash continuously or turn on and 4WD control module comes into fail-safe mode. For details of fail safe
mode, refer to “Fail-Safe Table”.
– 2WD/4WD switch
– Coupling air temperature sensor
– Coupling assembly
• DTC can be checked by using SUZUKI scan tool (3) connected to DLC (4).
• When 4WD control module detects any malfunction, 4WD control module will switch off the current to coupling
assembly and vehicle is changed to 2WD position.

Record details of the problem (failure, complaint) and how it occurred as described by the customer.
For this purpose, use of such a questionnaire form as shown in the following will facilitate collecting information to the
point required for proper analysis and diagnosis.

Step 2. DTC check, record and clearance
First, referring to “DTC Check”, check DTC and pending
DTC. If DTC exists, print or write down DTC and then
clear malfunction DTC(s) by referring to “DTC
Clearance”. Malfunction DTC indicates malfunction in
the system but it is not possible to know from it whether
the malfunction is occurring now or it occurred in the
past and normal condition has been restored. In order to
know that, check symptom in question according to Step
5 and then recheck DTC according to Step 6.
Diagnosing a trouble based on the DTC in this step only
or failure to clear the DTC in this step may result in an
faulty diagnosis, trouble diagnosis of a normal circuit or
difficulty in troubleshooting which is otherwise
unnecessary.
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 4WD control
system referring to “Visual Inspection”.
Step 5. Trouble symptom confirmation
Check trouble symptoms based on information obtained
in “Step 1. Customer complaint analysis: ” and “Step 2.
DTC check, record and clearance: ”.
Also, reconfirm DTC according to “DTC Confirmation
Procedure” described in each DTC flow.
Step 6 and 7. Rechecking and record of DTC
Refer to “DTC Check” for checking procedure.
Step 8. 4WD control symptom diagnosis
Check the parts of the system suspected as a possible
cause referring to “4WD Control Symptom Diagnosis”.
Step 9. Troubleshooting for DTC
Based on the DTC indicated in Step 6 / 7 and referring to
“applicable DTC flow”, locate the cause of the trouble,
namely in a sensor, switch, wire harness, connector,
coupling assembly, 4WD control module or other part
and repair or replace faulty parts.
Step 10. Check for intermittent problem
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
vehicle is free from any abnormal conditions. If what has
been repaired is related to the malfunction DTC, clear
the DTC once and check to ensure that no malfunction
DTC is indicated.4WD Position Indicator Operation CheckS6RW0D3204002
1) Turn ignition switch to OFF position.
2) Check that 4WD position indicators turn on for about
2 seconds and then turns off.
If any faulty condition is found, proceed to “4WD
Position Indicator Does Not Come ON at Ignition
Switch ON but Engine Stops” or “4WD Position
Indicator Remains ON Steady at Ignition Switch ON”.
4WD Control System Operation InspectionS6RW0D3204003
NOTE
• It automatically changes into “4WD-auto”
position, when the vehicle speed becomes
specified speed or more at “4WD-lock”
position. It is “4WD-auto” position until
switch will be selected to “4WD-lock”
position at next time.
• When ABS operates while changed of each
position, it is discontinued of change. End
of the ABS operation, and then returned to
the position of before.
1) Inspect switch operation from “4WD-auto” to “2WD”
as follows.
a) Start engine.
b) Push 2WD/4WD switch to “2WD” position.
c) Check that 4WD AUTO indicator and 4WD
LOCK indicator not come ON.
2) Inspect switch operation from “2WD” to “4WD-auto”
as follows.
a) Start engine.
b) Push 2WD/4WD switch to “AUTO” position.
c) Check that 4WD AUTO indicator comes ON
steady and 4WD LOCK indicator not come ON.
3) Inspect switch operation from “4WD-auto” to “4WD-
lock” as follows.
a) Start engine.
b) Push 2WD/4WD switch to “LOCK” position, and
keep it for 3 seconds or more.
c) Check that 4WD AUTO indicator not come ON
and 4WD LOCK indicator comes ON steady.
4) Inspect switch operation from “4WD-lock” to “4WD-
auto” as follows.
a) Start engine.
b) Push 2WD/4WD switch to “AUTO” position.
c) Check that 4WD AUTO indicator comes ON
steady and 4WD LOCK indicator not come ON.
