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.

Brake Interlock System ConstructionS7RS0B5101004
Shift Lock Solenoid Control
This system consists of shift lock solenoid control 
system and interlock cable control system.
The shift lock solenoid cont rol system is so designed 
that the select lever can not be shifted from “P” range 
position unless ignition switch is turned to “ON” or “ACC” 
position and the brake pedal is depressed.
And interlock cable control system is so designed that 
select lever cannot be shifted from “P” range position 
unless ignition switch is turned to “ACC” or “ON” 
position. Also, ignition key cannot be pulled out of key 
slot unless select le ver is in “P” range.
Shift Lock Solenoid Manual Release
When push down shift lock solenoid valve release button 
(1), select lever can be moved from “P” range position to 
another range even without depressing the brake pedal. 
(To shift select lever from “P” range to any other position, 
turn ignition switch to ACC or ON position.)
A/T Diagnosis General DescriptionS7RS0B5101005
This vehicle is equipped with an electronic transaxle 
control system, which controls the automatic shift up and 
shift down timing, TCC operation, etc. suitably to vehicle 
driving conditions.
TCM has an On-Board Diagnosis System which detects 
a malfunction in this system.
When diagnosing a trouble in transaxle including this 
system, be sure to have full understanding of the outline 
of “On-Board Diagnostic System Description” and each 
item in “Precautions in Diagnosing Trouble” and execute 
diagnosis according to “A/T System Check” to obtain 
correct result smoothly.
On-Board Diagnostic System DescriptionS7RS0B5101006
For automatic transaxle co ntrol system, TCM has the 
following functions. Refer to “Inspection of TCM and Its 
Circuits”.
• When ignition switch is turned ON with no malfunction  in A/T control system is detected, transmission 
warning light (1) lights for about 2 seconds after 
ignition switch is turned ON and then goes OFF for 
bulb check.
• When TCM detects a malfunction in A/T control  system, it indicates  transmission warning light (1) and 
stores malfunction DTC in its memory.
• It is possible to communicate with TCM through data  link connector (DLC) (3) by using SUZUKI scan tool 
(2). Diagnostic information can be checked and 
erased by using SUZUKI scan tool.
• For information about the following items, refer to “On- Board Diagnostic System De scription in Section 1A”
