Precautions

Precautions in Diagnosing Troubles

S6JB0A4600001

To ensure that the trouble diagnosis is done accurately
and smoothly, observe the following and follow
“Electronic Stability Program Check”.
• Diagnostic information stored in ESP

® 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, ESP

® warning light may light momentarily but

this does not indicate anything abnormal in ESP

®.

– 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 “Electronic Stability Program Check”.
Failure to follow it may result in incorrect diagnosis.
(Some other diagnosis trouble code may be stored by
mistake in the memory of ESP

® control module

during inspection.)

• When disconnecting ESP

® control module connector

(1), pull up lock lever (2) of connector.
When connecting, set the connector on ESP

hydraulic unit / control module assembly and pull
down the lock lever (2) until it locks.

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

ESP

® (ABS) control module (if equipped), 4WD

control module (if equipped), keyless start control
module (if equipped), immobilizer control module (if
equipped) combination meter and steering angle
sensor is established by CAN (Controller Area
Network). For more detail of CAN communication,
refer to “CAN Communication System Description:
For Petrol Engine Model in Section 1A” or “CAN
Communication System Description: For Diesel
Engine Model in Section 1A”.
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 Service

S6JB0A4600002

When connector is connected to ESP

® hydraulic unit /

control module assembly, do not disconnect connectors
of sensors with ignition switch ON. Otherwise, DTC will
be set in ESP

® control module.

Precautions in Hydraulic Unit Operation Check

S6JB0A4600003

ESP

® 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 in
Section 4E” should be performed to confirm the correct
brake pipe connection in the following cases.
• ESP

® hydraulic unit / control module assembly was

replaced.

• Brake pipe and/or hose were replaced.

[A]: Disconnect

C: Pull up to disconnect

[B]: Connect

D: Pull down to connect

4F-2 Electronic Stability Program:

Precautions in Sensor Calibration

S6JB0A4600004

ESP

® control module stores calibration points data of yaw rate / G sensor assembly and master cylinder pressure

sensor. Steering angle sensor stores calibration point data of itself.
TCS and stability control system use these sets of data.
When the following operation is done, calibration should be performed since the original calibration points are deleted.

Perform sensor calibration according to “Sensor Calibration”.

Precautions in Speedometer Test or Other Tests

S6JB0A4600005

When performing speedometer or a bench test while rotating a tire, ESP

® function must be kept at stop. It is possible

to stop ESP

® function temporarily by ESP® OFF switch. In this case, however, the function is forced to come back to

work when the speed exceeds 30 km/h (18.5 mph) and may hinder accurate testing.
There are two ways to stop the ESP

® function completely as described bellow.

• Connect the SUZUKI scan tool, set to the “MISC. TEST” mode to stop the ESP

® function. Refer to SUZUKI scan

tool operator's manual for further details.

• Disconnect the connector of the steering angle sensor, and ESP

® function is forced to enter the fail-safe mode,

then ESP

® function is stopped.

However, when this method is used, DTC remains in the memory of the ESP

® control module. Therefore, after the

test, re-connect the connector, clear DTC in the memory of the ESP

® control module. And calibrate steering angle

sensor referring to “Sensor Calibration”.

General Description

Electronic Stability Program Description

S6JB0A4601001

Electronic Stability Program (ESP

®) main function is to

control ABS / EBD, TCS and stability.
• ABS / EBD

ABS function is that four wheel brake forces are
independently varied with referring each wheel slip
condition.
EBD function is that front and rear wheel braking
forces are varied with referring loading distribution of
the vehicle.
ABS improves the vehicle stability, controllability and
braking performance.
For the details, refer to “ABS Description in Section
4E”.

• TCS (Traction Control System)

TCS function is that engine torque is controlled and
brake is applied with referring wheel spin condition
during vehicle starting and accelerating.

• Stability control system

Stability control system is that engine torque is
controlled and brake is applied with referring vehicle
condition (over steering, under steering) during
cornering.

ESP

® Hydraulic Unit / Control Module

Assembly Description

S6JB0A4601002

ESP

® control module is a component of ESP® hydraulic

unit / control module assembly and has the following
functions.

Self-Diagnosis Function
ESP

® control module monitors each input and output

signals. When ESP

® control module detects any

malfunction, some of ABS warning light (1), EBD
warning light (brake warning light) (2), ESP

® warning

light (3), SLIP indicator light (4), ESP

® OFF light (5) are

turned ON and indicate the abnormality to driver.

Sensor

Procedures required calibration

Steering angle sensor

• Power is not supplied to steering angle sensor. (battery and/or fuse is removed.)
• Steering angle sensor is replaced.
• Power is not supplied to ESP

® control module. (battery, fuse and/or connector is

removed.)

• ESP

® hydraulic unit / control module assembly is replaced.

Master cylinder pressure sensor • ESP

® hydraulic unit / control module assembly is removed or replaced.

Yaw rate / G sensor assembly

• Yaw rate / G sensor assembly is removed or replaced.
• ESP

Electronic Stability Program: 4F-3

• When ignition switch is turned ON, ABS warning light,

EBD warning light, ESP

® warning light, SLIP indicator

light and ESP

® OFF light light for 2 seconds to check

its circuit.

• When no abnormality is detected (the system is in

good condition), ABS warning light, EBD warning
light, ESP

® warning light, SLIP indicator light and

ESP

® OFF light turn OFF after 2 seconds.

• When an abnormality in the system is detected, some

of ABS warning light, EBD warning light (brake
warning light), ESP

® warning light, SLIP indicator

light and/or ESP

® OFF light are turned ON and the

area where that abnormality lies is stored in the
memory in ESP

® control module.

Fail-Safe Mode
When ESP

® control module detects abnormality, the

system goes into fail-safe mode. And some of functions
of ABS, TCS, stability control system are shut down. For
details of fail safe mode, refer to “Fail-Safe Table”.

Warning Light, Indicator Light Description

S6JB0A4601003

There are five types of warning light and indicator light in instrument cluster, which are controlled by ESP

® control

module. They give warning / indication to driver by changing the modes light ON / blinking / light OFF.
