Repair Instructions
Parking Brake Inspection and AdjustmentS7RS0B4406001
Inspection
Hold center of parking brake lever grip and pull it up with
200 N (20 kg, 44 lbs) force.
With parking brake lever pulled up as shown, count
ratchet notches. There should be 4 to 9 notches.
Also, check if both right and left rear wheels are locked
firmly.
To count number of notches easily, listen to click sounds
that ratchet makes while pulling parking brake lever
without pressing its button.
One click sound corresponds to one notch.
If number of notches is out of specification, adjust cable
referring to adjustment procedure so as to obtain
specified parking brake stroke.
NOTE
Check tooth tip of each notch for damage or
wear.
If any damage or wear is found, replace
parking brake lever.

Adjustment
NOTE
Make sure for the following conditions before
cable adjustment.
• No air is trapped in brake system.
• Brake pedal travel is proper.
• Start engine and then brake pedal has been depressed at least 3 times with about
160 N (16.0 kg, 35.3 lbs) load.
• Parking brake lever (1) has been pulled up a few times with about 200 N (20 kg, 44 lbs)
load.
If parking brake cable is replaced with new
one, pull up parking brake lever a few
times with about 500 N ⋅m (50 kg, 110 lbs)
force.

1) Release parking brake lever (1).
2) Loosen parking brake lever adjust nut (2) fully.
3) Make sure that lever (3) contacts pin (4).
4) Pull up parking brake lever 1 notch.
5) Rotate rear wheel by hand and fasten parking lever adjust nut until dragging rear wheel lightly.

6) Release parking brake lever and then make sure that there is no drag in rear wheel.
If there is, repeats go to step 2).
7) Make sure that the number of notch is between 4 and 9 when operating parking brake lever.
8) If the number of notch is not between 4 and 9, replace parking brake cable and/or inspect rear
brake caliper.

Precautions
Precautions in Diagnosing TroublesS7RS0B4500001
To ensure that the trouble diagnosis is done accurately
and smoothly, observe the following and follow “ABS
Check”.
• Diagnostic information stored in ABS cont rol module
memory can be cleared as well as checked by using
SUZUKI scan tool. Before us ing 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 “Precautions for Electrical Circuit Service in Section 00” befo re 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 co ntrol module connector
(1), pull down lock lever (2) of connector.
When connecting, set the connector on ABS control
module assembly and pull up the lock lever (2) until it
locks. • Communication of ECM,
BCM, ABS control module,
keyless start control module (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 ServiceS7RS0B4500002
When connector is connected to ABS 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 CheckS7RS0B4500003
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 “ABS Hydraulic Unit Operation Check”
should be performed to confirm the correct brake pipe
connection in the following cases.
• ABS hydraulic unit / cont rol module assembly was
replaced.
• Brake pipe and/or hose ware replaced.

General Description
ABS DescriptionS7RS0B4501001
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 light s to inform abnormality
when system fails to operate properly.
• ABS hydraulic unit / cont rol module assembly is
incorporated ABS co ntrol 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 supp ly 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.
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 proportion ing valve, by the signal from
wheel sensor independently of change of load due to
load capacity and so on. An d if the EBD system fails to
operate properly, the brake warning light lights to inform
abnormality.
ABS Hydraulic Unit / Control Module Assembly
Description
S7RS0B4501002
ABS control module is a component of ABS hydraulic
unit / control module asse mbly and has the following
functions.
Self-Diagnosis Function
ABS control module diagnose s 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 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 th e 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.
