Problem symptom confirmation
Check if what the customer claimed in “Customer
Questionnaire” is actually found in the vehicle and if that
symptom is found, whether it is identified as a failure.
(This step should be shared with the customer if
possible.) Check warning lights related to brake system
referring to “EBD Warning Light (Brake Warning Light)
Check” and “ABS Warning Light Check”.
DTC check, record and clearance
Perform “DTC Check” proced ure, record it and then
clear it referring to “DTC Clearance”.
Recheck DTC referring to “DTC Check”.
When DTC which is recorded at DTC check procedure is
detected again after performi ng DTC clearance, go to
“Step 4: ABS Check: ” to proceed the diagnosis.
When DTC which is recorded at DTC check procedure is
not indicated anymore after performing DTC clearance,
ABS control module does not perform the system
diagnosis, or temporary abnormality may occur,
therefore go to “Step 2: Driving Test: ” to proceed the
diagnosis.
Step 2: Driving Test
Test drive the vehicle at 40 km/h for more than a minute
and check if any trouble symptom (such as abnormal
lighting of ABS warn ing light) exists.

switch ON, driving test as described is not necessary.
Proceed to Step 3.
Step 3: DTC Check
Recheck DTC referring to “DTC Check”.
Step 4: ABS Check
According to ABS Check for the DTC confirmation in
Step 3, locate the cause of the trouble, namely in a
sensor, switch, wire harness, connector, actuator
assembly or other part and repair or replace faulty parts.
Step 5: Brakes Diagnosis
Check the parts or system suspected as a possible
cause referring to “Brakes Symptom Diagnosis in
Section 4A” and based on symptoms appearing on the
vehicle (symptom obtained through Steps 1 and 2 and
repair or replace faulty parts, if any).
Step 6: Check for Intermittent Problem
Check parts where an intermittent trouble is easy to
occur (e.g., wire harness, con nector, etc.), referring to
“Intermittent and Poor Connection Inspection in Section
00” and related circuit of trouble code recorded in Step 1
to 3.
Step 7: Final Confirmation Test

Precautions
Precautions in Diagnosing TroublesS7RS0B4600001
To ensure that the trouble diagnosis is done accurately
and smoothly, observe the following and follow
“Electronic Stability Program System Check”.
• Diagnostic information stored in ESP® control 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, ESP ® warning lamp 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 use the trouble diagnosis procedure as described in “Electronic Stability Program System
Check”. Failure to follow it may resu lt 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 down the lock lever (2) of connector.
When connecting, set the connector on ESP ®
hydraulic unit / control module assembly and pull up
the lock lever (2) until it locks. • Communication of ECM, BCM, ESP
® control module,
keyless start control module (if equipped), steering
angle sensor 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 handling CAN communication
line.
Precautions in On-Vehicle ServiceS7RS0B4600002
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 CheckS7RS0B4600003
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 “ESP ® Hydraulic Unit Operation
Check” should be performed to confirm the correct brake
pipe connection in the following cases.
• ESP® hydraulic unit / contro l module assembly was
replaced.
• Brake pipe and/or hose were replaced.
Precautions in Sensor CalibrationS7RS0B4600004
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, sensor calibration should be performed since the original calibration points are
deleted.

Yaw rate / G sensor
The yaw rate / G sensor consists of the yaw rate (angular velocity in the vehicle turning direction) sensor and right-left
G (acceleration in right-left direction) sensor and is mounted to the P/S controller B/K at the lower part of the center
console. It detects the angular velocity in the vehicle turn ing direction and movement in the right-left direction, and
then it sends that information to ESP ® control module.
Wheel speed sensor
The vehicle speed is detected by the hall IC type wheel speed sensor (1) and encoder (4). The wheel speed sensor is
fixed to the knuckle and includes a hall IC (3) having 2 hall elements (2).
The encoder consisting of a permanent ma gnet which has S/N electrodes turns inside of the wheel hub along with the
wheel. The wheel speed sensor outputs alternate current.
As the cycle of the alternate current is in proportion to the revolution speed of the encoder, this AC signal (5) is
converted into the voltage signal in the ESP ® control module (6) for detection of the wheel speed.
ESP ® Hydraulic Unit / Control Module
Assembly Description
S7RS0B4601002
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 lamp (1), EBD
warning lamp (brake warning lamp) (2), ESP ® warning
lamp (3), SLIP indicator lamp (4), ESP ® OFF lamp (5)
are turned ON and indicate the abnormality to driver.
• When ignition switch is turned ON, ABS warning lamp, EBD warning lamp, ESP ® warning lamp, SLIP
indicator lamp and ESP ® OFF lamp light for 2
seconds to check its circuit.
• When no abnormality is detected (the system is in good condition), ABS warning lamp, EBD warning
lamp, ESP ® warning lamp, SLIP indicator lamp and
ESP ® OFF lamp turn OFF after 2 seconds.
• When an abnormality in the system is detected, some of ABS warning lamp, EBD warning lamp (brake
warning lamp), ESP ® warning lamp, SLIP indicator
lamp and/or ESP ® OFF lamp 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, re fer to “Fail-Safe Table”.
