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.
