PRECAUTION IN DIAGNOSING TROUBLE

Don't disconnect couplers from PCM (ECM), battery cable from battery, PCM ground wire harness from engine
or main fuse before checking the diagnosis information (DTC, freeze frame data, etc.) stored in PCM memory.
Such disconnection will clear memorized information in PCM memory.

Using SUZUKI scan tool (Tech-1), or also generic scan tool for vehicle without monitor connector, the diagnostic
information stored in PCM memory can be checked and cleared as well. Before its use, be sure to read Operator's
(instruction) Manual supplied with it carefully to have good understanding of its functions and usage.

Priorities for diagnosing troubles (Only for vehicle without monitor connector)
If two or more diagnostic trouble codes (DTCs) are stored, proceed to the flow table of the DTC which was de-
tected earliest in the order and follow the instruction in that table.
If no instructions are given, troubleshoot diagnostic trouble codes according to the following priorities.
1. Diagnostic trouble codes (DTCs) other than DTC P0171 / P0172 (Fuel system too lean / too rich) and DTC
P0400 (EGR flow malfunction)
2. DTC P0171 / P0172 (Fuel system too lean / too rich) and DTC P0400 (EGR flow malfunction)

Be sure to read ªPrecautions for Electrical Circuit Serviceº in Section 0A before inspection and observe what is
written there.

PCM replacement
When substituting a known-good PCM, check for following conditions.
Neglecting this check may result in damage to good PCM.
± All relays and actuators have resistance of specified value.
± MAF sensor, MDP sensor, TP sensor and fuel tank pressure sensor are in good condition. Also, the power
circuit of these sensors is not shorted to the ground.

1. CUSTOMER COMPLAINT ANALYSIS
Record details of the problem (failure, complaint) and how it occurred as described by the customer.
For this purpose, use of such a inspection form will facilitate collecting information to the point required for proper
analysis and diagnosis.
2. DIAGNOSTIC TROUBLE CODE (DTC)/FREEZE FRAME DATA CHECK, RECORD AND CLEARANCE
First, referring to DTC check section, check DTC (including pending DTC). If DTC exists, print or write down
DTC and freeze frame data and then clear them by referring to DTC clearance section. DTC indicates malfunc-
tion 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 unnec-
essary.
3 and 4. VISUAL INSPECTION
As a preliminary step, be sure to perform visual check of the items that support proper function of the A / T and
engine referring to Visual Inspection section.
5. TROUBLE SYMPTOM CONFIRMATION
Check trouble symptoms based on information obtained in Step 1 ªCUSTOMER COMPLAINT ANALYSISº and
Step 2 ªDTC/FREEZE FRAME DATA CHECKº.
Also, recheck DTC according to ªDTC Confirmation Procedureº described in each ªDTC FLOW TABLEº.
6 and 7. RECHECKING AND RECORD OF DTC/FREEZE FRAME DATA
Refer to ªDTC Checkº section for checking procedure.
8. A/T BASIC CHECK AND TROUBLE DIAGNOSIS TABLE
Perform A / T basic check according to the ªA / T Basic Check Flow Tableº first. When the end of the flow table
has been reached, check the parts of the system suspected as a possible cause referring to TROUBLE DIAG-
NOSIS TABLE and based on symptoms appearing on the vehicle (symptoms obtained through steps of custom-
er complaint analysis, trouble symptom confirmation and/or A / T basic check) and repair or replace faulty parts,
if any.
9. DIAGNOSTIC TROUBLE CODE FLOW TABLE
Based on the DTC indicated in Step 6 and 7 and referring to ªDIAGNOSTIC TROUBLE CODE FLOW TABLEº
in this section, locate the cause of the trouble, namely in a sensor, switch, wire harness, connector, actuator,
PCM or other part and repair or replace faulty parts.
10. CHECK FOR INTERMITTENT PROBLEM
Check parts where an intermittent trouble is easy to occur (e.g., wire harness, connector, etc.), referring to
ªINTERMITTENT AND POOR CONNECTIONº in Section 0A and related circuit of DTC recorded in Step 2.
11. FINAL CONFIRMATION TEST
Confirm that the problem symptom has gone and the A / T is free from any abnormal conditions.
If what has been repaired is related to the malfunction DTC, clear the DTC once, set conditions under which
DTC was detected and A / T and/or vehicle was repaired and confirm that no DTC is indicated.

MANUAL ROAD TEST
This test check the gear being used in ªLº, ª2º or ªDº range when
driven with unoperated gear shift control system. Test drive vehicle
on a level road.
NOTE:
Before this test, check diagnostic trouble code (DTC).
1) Disconnect coupler of shift solenoid valves on transmission.
WARNING:
To avoid the danger of being burned, do not touch the hot
exhaust system when disconnecting shift solenoid
valves coupler.
2) With select lever in ªPº, start engine and warm it up.
3) With select lever in ªLº range, start vehicle and accelerate to 20
km/h (12.5 mile/h). Check in this state that 1st gear is being
used.
4) At 20 km/h (12.5 mile/h), shift select lever to 2 range and acceler-
ate to 40 km/h (25 mile/h). Check in this state that 3rd gear is
being used.
5) At 40 km/h (25 mile/h), shift select lever to D range and check
that O/D gear is used when speed is higher than 40 km/h (25
mile/h).
6) After above checks, stop vehicle then engine, and connect shift
solenoids coupler with ignition switch OFF.
WARNING:
To avoid the danger of being burned, do not touch the hot
exhaust system when connecting shift solenoid valves
coupler.
7) Clear DTC with scan tool.
TIME LAG TEST
This test is to check conditions of clutch, reverse brake and fluid
pressure. ªTime lagº means time elapsed since select lever is
shifted with engine idling till shock is felt.
1) With chocks placed before and behind front and rear wheels re-
spectively, depress brake pedal.
2) Start engine.
3) With stop watch ready, shift select lever from ªNº to ªDº range
and measure time from that moment till shock is felt.
4) Similarly measure time lag by shifting select lever from ªNº to ªRº
range.
Specification for ªNº
ªDºLess than 1.2 sec.
time lagªNº
ªRºLess than 1.5 sec.
NOTE:

When repeating this test, be sure to wait at least minute
after select lever is shifted back to ªNº range.

Engine should be warmed up fully for this test.

WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System

Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to ªAir Bag System Components and Wiring Location Viewº under ªGener-
al Descriptionº in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and ªService Precau-
tionsº under ªOn-Vehicle Serviceº in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either of these two conditions may
result in severe injury.

Technical service work must be started at least 90 seconds after the ignition switch is turned to the
ªLOCKº position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
