Precautions
Precautions in Diagnosing TroubleS7RS0B5100001
• Do not disconnect couplers from TCM, battery cable from battery, TCM ground wire harness from engine or
main fuse before checking the diagnostic information
(DTC, freeze frame data, etc.) stored in TCM memory.
Such disconnection will clea r memorized information
in TCM memory.
• Diagnostic information stored in TCM memory can be cleared as well as checked by using SUZUKI scan
tool or generic scan tool. Before using scan tool, read
its Operator’s (Instruction) Manual carefully to have
good understanding as to what functions are available
and how to use it.
It is indistinguishable wh ich module turns on MIL
because not only ECM but also TCM turns on MIL.
Therefore, check both ECM and TCM for DTC when
MIL lights on.
When checking TCM 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 TCM.
– Generic scan tool displays DTC detected by each of ECM and TCM simultaneously.
• Using SUZUKI scan tool the diagnostic information stored in TCM memory can be checked and cleared
as well. Before its use, be sure to read Operator’s
Manual supplied with it carefully to have good
understanding of its functions and usage.
• Be sure to read “Precautions for Electrical Circuit Service in Section 00” befo re inspection and observe
what is written there.
• TCM replacement
– When substituting a known-good TCM, check that all relays and actuators have resistance of
specified value.
Neglecting this check may result in damage to good
TCM.
• Communication of ECUs , ECM, TCM, ABS control
module, keyless start control module and BCM is
established by CAN (Controller Area Network).
Therefore, handle CAN communication line with care
referring to “Precaution for CAN Communication
System in Section 00”.
Precautions for Disassembly and ReassemblyS7RS0B5100002
When repairing automatic transaxle, it is necessary to
conduct the on-vehicle test to investigate where the
cause of the trouble lies first.
Then whether overhaul should be done or not is
determined. If the transaxle is disassembled without
such preliminary procedure, not only the cause of the
trouble would be unknown, but also a secondary trouble
may occur and often time would be wasted.
As the automatic transaxle consists of high precision
component, the following cautions should be strictly
observed when handling its parts in disassembly and
reassembly.
• Disassembling valve body assembly is prohibited
essentially. However, a few parts can be
disassembled. When disassembling valve body
component parts, confirm whether their parts are
allowed to disassemble or not referring to “Valve Body
Assembly Disassembly and Reassembly”.
• When component part of forward clutch, direct clutch, 2nd brake and/or O/D and 2nd coast brake, namely
clutch disc, brake disc, retaining plate and/or
separator plate, have been replaced, all learned
contents, which have been stored in TCM memory by
executing learning control, should be initialized
referring to “Learning Control Initialization”.
• Make sure to wash dirt off from the transaxle so that no such dirt will enter the transaxle during
dismounting and remounting.
• Select a clean place free from dust and dirt for overhauling.
• Place a rubber mat on the work bench to protect parts from damage.
• Work gloves or shop cloth should not be used. (Use a nylon cloth or a paper towel.)
• When separating the case joint, do not pry with a screwdriver or such but tap with a plastic hammer
lightly.
• Make sure to wash dirt off from the transaxle so that no such dirt will enter the transaxle during
disassembly and reassembly.
• Wash the disassembled parts in ATF (Automatic Transaxle Fluid) or kerosene (using care not to allow
ATF or kerosene to get on your face, etc.) and confirm
that each fluid passage is not clogged by blowing air
into it. But use kerosene to wash the discs, resin
washers and rubber parts.
• Replace each gasket, oil seal and O-ring with a new one.
• Apply ATF to sliding or rotating parts before
reassembly.

Step 2. DTC / Freeze Frame Data Check, Record and Clearance
First, referring to “DTC Check”, check DTC and pending DTC. If DTC exists, print or write down DTC and freeze frame
data 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 fa ilure 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 engine and
automatic transaxle 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
/ Freeze Frame Data 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 and Freeze Frame Data
Refer to “DTC Check” for checking procedure.
Step 8. A/T Basic Check and A/T Symptom Diagnosis
Perform basic check of A/T according to “A/T Basic Check” first. When the end of the flow has been reached, check
the parts of the system suspected as a possible cause referring to “A/T Symptom Diagnosis” and based on symptoms
appearing on the vehicle (symptoms obtained through step s of customer complaint analysis, trouble symptom
confirmation and/or A/T basic check) and re pair or replace faulty parts, if any.
Step 9. Troubleshooting for DTC
Based on the DTC indicated in Step 6 / 7 and referring to “a pplicable DTC flow”, locate the cause of the trouble,
namely in a sensor, switch, wire harness, connector, actuator, TCM 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 vehicl e 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.

Manual Road TestS7RS0B5104012
WARNING!
Carry out test in very little traffic area to prevent an accident.
Test requires 2 persons, a driver and a tester.

The purpose of this test is to judge whether causal factor of trouble which occurred in automatic transaxle is electrical
or mechanical by disconnecting valve body harness co nnector (1) and fixing automatic transaxle gear position.
1) Start engine and warm it up to normal operating temperature.
2) Turn ignition switch to OFF position and disconnect valve body harness connector (1).
3) Turn OFF all electrical loads. With select lever shifted to each ra nge (“L”, “2”, “3” and “D”), drive vehi cle at 1,000 rpm engine speed and then
check vehicle speed by referring to “Fixed gear position”.
If vehicle speed is not as specified in “Fix ed gear position” table, go to troubleshooting.
4) Connect valve body harness connector and clear DTC.
