Diagnostic Information and Procedures
Cranking System Symptom DiagnosisS7RS0B1904001
Possible symptoms due to starting system trouble would be as follows: 
• Starting motor does not run (or runs slowly)
• Starting motor runs but fails to crank engine
• Abnormal noise is heard
Proper diagnosis must be made to determine exactly where the cause of each trouble lies in battery, wiring harness, 
(including starting motor switch), starting motor or engine.
Do not remove motor just because starting motor does not  run. Check the following items and narrow down scope of 
possible causes.
1) Condition of trouble
2) Tightness of battery terminals (including ground cable  connection on engine side) and starting motor terminals
3) Discharge of battery
4) Mounting of starting motor

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.

Troubleshooting
Brake Interlock System InspectionS7RS0B5104047
1) Check that select lever cannot be moved to any other range from “P” range position when ignition 
switch key is at ACC position,  at LOCK position or it 
is removed from keyhole of ignition switch, or brake 
pedal is not depressed. 2) Shift select lever to “P” range position, release knob 
button and check for the following.
• Ignition key can be turned between LOCK and ACC positions back and forth and also it can be 
removed from ignition switch.
Step Action Yes No
1 Check TCM back-up power circuit
1) Disconnect TCM connector with ignition switch OFF.
2) Check for proper connection to TCM at “C34-24” 
terminal.
3) If OK, check voltage at terminal “C34-24” of  disconnected TCM connector.
Is it 10 – 14 V? Go to Step 2. “WHT/RED” circuit open 
or shorted to ground.
2 Check TCM power circuit
1) Disconnect TCM connector with ignition switch OFF.
2) Check for proper connection to TCM at “C34-6” terminal.
3) If OK, turn ignition switch ON and check voltage at 
terminal “C34-6” of disconnected TCM connector.
Is it 10 – 14 V? Go to Step 4. Go to Step 3.
3 Check A/T relay operation
1) Check A/T relay operation  referring to “A/T Relay 
Inspection”.
Is check result satisfactory? “YEL/BLK”, “YEL/BLU”, 
“LT GRN/BLK” or “BLK” 
circuit for power supply 
open.
Replace A/T relay.
4 Check TCM ground circuit
1) Turn ignition switch OFF.
2) With TCM connectors disconnected, check for proper 
connection to TCM at “C34-1” / “C34-23” terminal.
3) If OK, check resistance between “C34-1” / “C34-23”  terminal of disconnected  TCM connector and body 
ground.
Is continuity indicated? TCM power and ground 
circuits are in good 
condition.
“BLK” circuit for TCM 
ground open.

Installation
Reverse removal procedure noting the following.
• Connect TCM connectors securely.
• If the vehicle is equipped with air bag system, be sure to enable air bag system after TCM is back in place. 
Refer to “Enabling Air Bag System in Section 8B”.
A/T Relay InspectionS7RS0B5106027
1) Disconnect negative cable at battery.
2) Remove A/T relay (2) from fuse and relay box (1).
3) Check that there is no continuity between terminal  “C” and “D”.
If continuity is indicated, replace A/T relay.
4) Connect battery positive (+ ) terminal to terminal “A” 
of A/T relay and battery negative (–) terminal to 
terminal “B” of A/T relay.
Check continuity between terminal “C” and “D” of A/T 
relay.
If continuity does not indicated, replace A/T relay.
Differential Side Oil Seal ReplacementS7RS0B5106028
1) Lift up vehicle and drain automatic transaxle fluid.
2) Remove drive shaft joints from differential gear of  transaxle. Refer to “Front Drive Shaft Assembly 
Removal and Installation in Section 3A” for 
procedure to disconnect drive shaft joints.
For differential side oil  seal removal, it is not 
necessary to remove drive shafts from steering 
knuckle.
3) Remove differential side oil seal (1) by using  screwdriver or the like.
