General Description
ABS DescriptionS6RW0D4501001
The ABS (Antilock Brake System) controls the fluid
pressure applied to the wheel cylinder of each brake
from the master cylinder so that each wheel is not locked
even when hard braking is applied.
This ABS has also the following function.
While braking is applied, but before ABS control
becomes effective, braking force is distributed between
the front and rear so as to prevent the rear wheels from
being locked too early for better stability of the vehicle.
The main component parts of this ABS include the
following parts in addition to those of the conventional
brake system.
• Wheel speed sensor which senses revolution speed
of each wheel and outputs its signal.
Rear wheel speed sensor of 4WD vehicle is
integrated in rear wheel hub assembly and supplied
as rear wheel hub assembly part.
Front wheel speed sensor and rear wheel speed
sensor of 2WD model are separated from wheel hub
assembly and supplied as spare parts.
• ABS warning light which lights to inform abnormality
when system fails to operate properly.• ABS hydraulic unit / control module assembly is
incorporated ABS control module, ABS hydraulic unit
(actuator assembly), solenoid valve power supply
driver (transistor), solenoid valve driver (transistor),
pump motor driver (transistor).
– ABS control module which sends operation signal
to ABS hydraulic unit to control fluid pressure
applied to each wheel cylinder based on signal
from each wheel speed sensor so as to prevent
wheel from locking.
– ABS hydraulic unit which operates according to
signal from ABS control module to control fluid
pressure applied to wheel cylinder of each 4
wheels.
– Solenoid valve power supply driver (transistor)
which supplies power to solenoid valve in ABS
hydraulic unit.
– Solenoid valve driver (transistor) which controls
each solenoid valves in ABS hydraulic unit.
– Pump motor driver (transistor) which supplies
power to pump motor in ABS hydraulic unit.
• G sensor which detects body deceleration speed for
4WD model.
This ABS is equipped with Electronic Brake force
Distribution (EBD) system that controls a fluid pressure
of rear wheels to best condition, which is the same
function as that of proportioning valve, by the signal from
wheel sensor independently of change of load due to
load capacity and so on. And if the EBD system fails to
operate properly, the brake warning light lights to inform
abnormality.

Precautions
Precautions in Diagnosing TroubleS6RW0D5100001
• 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 clear memorized information
in TCM memory.
• Diagnostic information stored in TCM memory can be
cleared as well as checked by using SUZUKI scan
tool or CAN communication OBD 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 which 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.
– CAN communication OBD generic scan tool
displays DTC detected by each of ECM and TCM
simultaneously.
• Be sure to read “Precautions for Electrical Circuit
Service in Section 00” before 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 ECM, BCM, combination meter,
keyless start control module (if equipped), ABS
control module, 4WD control module (if equipped),
TCM and DLC, is established by CAN (Controller
Area Network). (For more detail of CAN
communication for ECM, refer to “CAN
Communication System Description”). Therefore,
handle CAN communication line with care referring to
“Precaution for CAN Communication System in
Section 00”.
Precautions for Disassembly and ReassemblyS6RW0D5100002
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.

General Description
A/T DescriptionS6RW0D5101001
This automatic transaxle is electronic control full automatic transaxle with forward 3-speed plus overdrive (O/D) and
reverse 1-speed.
The torque converter is a 3-element, 1-step and 2-phase type and is equipped with an automatically controlled lock-up
mechanism.
The gear change device consists of a ravigneau type planetary gear unit, 3 multiple disc type clutches, 3 multiple disc
type brakes and 2 one-way clutches.
The hydraulic pressure control device consists of a valve body assembly, pressure control solenoid valve (linear
solenoid), 2 shift solenoid valves, TCC solenoid valve (TCC pressure control solenoid valve) (linear solenoid) and a
timing solenoid valve. Optimum line pressure complying with engine torque is produced by the pressure control
solenoid valve in dependence upon control signal from transmission control module (TCM). This makes it possible to
control the line pressure with high accuracy in accordance with the engine power and running conditions to achieve
smooth shifting characteristics and high efficiency.
A clutch-to-clutch control system is provided for shifting between 3rd gear and 4th gear. This clutch-to-clutch control
system is made to function optimally, so that hydraulic pressure controls such as shown below are conducted.
• When upshifting from 3rd gear to 4th gear, to adjust the drain hydraulic pressure at releasing the forward clutch, a
timing solenoid valve is used to switch a hydraulic passage with an orifice to another during shifting.
• When downshifting from 4th gear to 3rd gear, to adjust the line pressure applied to the forward clutch at engaging
the forward clutch, a timing solenoid valve is used to switch a hydraulic passage with an orifice to another during
shifting.
• When upshifting from 3rd gear to 4th gear with engine throttle opened, to optimize the line pressure applied to the
forward clutch at releasing the forward clutch, the learning control is processed to compensate the switching timing
of the timing solenoid at every shifting.
• When downshifting from 4th gear to 3rd gear with engine throttle opened, to optimize the line pressure applied to
the forward clutch at engaging the forward clutch, the learning control is processed to compensate the line pressure
at every shifting.
Employing the ravigneau type planetary gear unit and this clutch-to-clutch control system greatly simplifies the
construction to make possible a lightweight and compact transaxle.
A line pressure learning control is conducted to provide optimum shifting time at every upshifting with engine throttle
opened. If long upshifting time is detected, the subsequent line pressure applied during upshifting is intensified. On the
contrary, if short upshifting time is detected, the subsequent line pressure applied during upshifting is weakened.
