Repair Instructions
Parking Brake Inspection and AdjustmentS6RW0D4406001
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 – 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
300 N (30 kg, 66 lbs) load.
• Parking brake lever 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.

After confirming that the conditions are all satisfied,
adjust parking brake lever stroke by loosening or
tightening adjust nut (1).
NOTE
Check brake drum for dragging after
adjustment.

Parking brake stroke
When lever is pulled up at 200 N (20 kg, 44 lbs): 4 to
9 notches

Precautions
Precautions in Diagnosing TroublesS6RW0D4500001
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 vehicle 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” and “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 up lock lever (2) of
connector.
When connecting, set the connector on ABS hydraulic
unit / control module assembly and pull down the lock
lever (2) until it locks.
• Communication of ECM, BCM, combination meter,
4WD control module (if equipped), keyless start
control module (if equipped), TCM (if equipped), data
link connector and ABS control module is established
by CAN (Control Area Network).
Therefore, be sure to read “Precautions for Installing
Mobile Communication Equipment in Section 00”
before inspection and handling CAN communication
line.
Precautions in On-Vehicle ServiceS6RW0D4500002
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.
[A]: Disconnect C: Pull up to disconnect
[B]: Connect D: Pull down to connect

ABS Hydraulic Unit / Control Module Assembly
Description
S6RW0D4501002
ABS control module is a component of ABS hydraulic
unit / control module assembly and has the following
functions.
Self-Diagnosis Function
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 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.
CAN Communication System DescriptionS6RW0D4501003
Refer to “CAN Communication System Description in Section 1A” for CAN communication system description. ABS
control module communicates control data with each control module as follows.
