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.

On-Board Diagnostic System DescriptionS6RW0D5101005
NOTE
There are two types of OBD system
depending on the vehicle specification.For
identification, refer to “Precaution on On-
Board Diagnostic (OBD) System in Section
1A”.

For automatic transaxle control system, TCM has the
following functions.
• For Euro OBD model, when the ignition switch is
turned ON with the engine at a stop, MIL (1) turns ON
to check the bulb of the MIL.
• For Euro OBD model, when TCM detects a
malfunction in A/T control system TCM desires turning
on MIL and stores malfunction DTC in TCM memory.
(If it detects that continuously 3 driving cycles are
normal after detecting a malfunction, however, it
makes MIL turn OFF although DTC stored in its
memory will remain.)
• For Euro OBD model, it is possible to communicate
with TCM through data link connector (DLC) (2) by
using not only SUZUKI scan tool (3) but also CAN
communication OBD generic scan tool. (Diagnostic
information can be checked and erased by using scan
tool.)
• For non-Euro-OBD model, when ignition switch is
turned ON and no malfunction in A/T control system is
detected, transmission warning light (4) lights for
about 2 seconds after ignition switch is turned ON and
then goes OFF for bulb check.• For non-Euro-OBD model, when TCM detects a
malfunction in A/T control system, it indicates
transmission warning light (4) and stores malfunction
DTC in its memory.
• For information about the following items, refer to “On-
Board Diagnostic System Description in Section 1A”.
– Warm-up cycle
– Driving cycle
– 2 driving cycle detection logic
– Pending DTC
– Freeze frame date
