4) Remove brake drum. Refer to “Rear Brake Drum

Removal and Installation in Section 4C”.

5) Disconnect parking brake cable from brake shoe

lever referring to “Rear Brake Shoe Removal and
Installation in Section 4C”.

6) Remove parking brake cable and parking cable

bracket.

Installation
Install it by reversing removal procedure, noting the
following points.
• Install clamps properly referring to “Parking Brake

Cable Location”.

• Tighten bolts and nuts to specified torque referring to

“Parking Brake Cable Location”.

• Adjust parking brake cable. Refer to “Parking Brake

Check and Adjustment”.

• Check brake drum for dragging and brake system for

proper performance. Brake test should be performed.

Precautions

Precautions in Diagnosing Troubles

S6JB0A4500001

To ensure that the trouble diagnosis is done accurately
and smoothly, observe the following and follow “ABS
Check”.
• Diagnostic information stored in ABS control module

memory can be cleared as well as checked by using
SUZUKI 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.

• If the vehicles was operated in any of the following

ways, ABS warning light may light momentarily but
this does not indicate anything abnormal in ABS.
– The vehicle was driven with parking brake pulled.
– The vehicle was driven with brake dragging.
– The vehicle was stuck in mud, sand, etc.
– Wheel spin occurred while driving.
– Wheel(s) was rotated while the vehicle was jacked

up.

• Be sure to read “Precaution for CAN Communication

System in Section 00” before inspection and observe
what is written there.

• Be sure to use the trouble diagnosis procedure as

described in “ABS Check”. Failure to follow it may
result in incorrect diagnosis. (Some other diagnosis
trouble code may be stored by mistake in the memory
of ABS control module during inspection.)

• When disconnecting ABS hydraulic unit / control

module connector (1), pull down lock lever (2) of
connector.
When connecting, set the connector on ABS hydraulic
unit / control module assembly and pull up the lock
lever (2) until it locks.

• Communication of ECM, TCM (A/T model), BCM,

ABS control module, 4WD control module (if
equipped), keyless start control module (if equipped),
immobilizer control module (ICM) (if equipped),
steering angle sensor (if equipped) and combination
meter is established by CAN (Controller Area
Network).
Therefore, be sure to read “Precautions for Installing
Mobile Communication Equipment in Section 00”
before inspection and handle CAN communication
line.

Precautions in On-Vehicle Service

S6JB0A4500002

When connector is connected to ABS hydraulic unit /
control module assembly, do not disconnect connectors
of sensors with ignition switch ON. Otherwise, DTC will
be set in ABS control module.

Precautions in Hydraulic Unit Operation Check

S6JB0A4500003

ABS hydraulic unit / control module assembly function is
checked by correct wheel lock / release condition when
brake pressure is pressurized / depressurized using
SUZUKI scan tool. The hydraulic unit operation check
referring to “Hydraulic Unit Operation Check” should be
performed to confirm the correct brake pipe connection
in the following cases.
• ABS hydraulic unit / control module assembly was

replaced.

• Brake pipe and/or hose were replaced.

[A]: Disconnect

C: Pull down to disconnect

[B]: Connect

D: Pull up to connect

4E-2 ABS:

General Description

ABS Description

S6JB0A4501001

ABS is controlled by ABS control module or by ESP

®

control module (if equipped).
ABS activation and control with ESP

® are done by

ESP

® hydraulic unit / control module assembly.

Regarding TCS and stability control excluding ABS
system with ESP

®, refer to Section 4F.

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.

• ABS warning light which lights to inform abnormality

when system fails to operate properly.

• ABS (ESP

®) hydraulic unit / control module assembly

is incorporated ABS (ESP

®) control module, ABS

(ESP

®) hydraulic unit (actuator assembly), solenoid

valve power supply driver (transistor), solenoid valve
driver (transistor), pump motor driver (transistor).
– ABS (ESP

®) control module which sends operation

signal to ABS (ESP

®) 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 (ESP

®) hydraulic unit which operates

according to signal from ABS (ESP

®) 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
(ESP

®) hydraulic unit.

– Solenoid valve driver (transistor) which controls

each solenoid valves in ABS (ESP

®) hydraulic unit.

– Pump motor driver (transistor) which supplies

power to pump motor in ABS (ESP

®) hydraulic

unit.

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.

Self-Diagnosis Description

S6JB0A4501002

ABS control module diagnoses conditions of the system
component parts (whether or not there is any
abnormality) all the time and indicates the results
(warning of abnormality occurrence and DTC) through
the ABS warning light (1) as described.

• When ignition switch is turned ON, ABS warning light

lights for 2 seconds to check its circuit.

• When no abnormality has been detected (the system

is in good condition), ABS warning light turns OFF
after 2 seconds.

• When an abnormality in the system is detected, ABS

warning light lights and the area where that
abnormality lies is stored in the memory of EEPROM
in ABS control module.
