Precaution for Vehicle Equipped with ESP®
System
S7RS0B0000015
• When testing with any of the following equipments
(when vehicle is tested by rotating wheels (tires)
under vehicle stop), be sure to deactivate ESP ®
system referring to “Precautions in Speedometer Test
or Other Tests in Section 4F” to obtain correct data.
– 2 or 4-wheel chassis dynamometer
– Speedometer tester
– Brake tester
–Etc.
ESP ® control module
• When ESP ® control module is removed / installed, do
not use impact wrenches which generate shock or
impact to avoid damaging sensors in ESP ® control
module.
• When any of the following operation is done, calibrate steering angle sensor referring to “Sensor Calibration
in Section 4F”.
– When battery or dome fuse is removed.
– When steering angle sensor is replaced.
Brake CautionS7RS0B0000014
CAUTION!
All brake fasteners are important attaching
parts in that they could affect the
performance of vital parts and systems, and/
or could result in major repair expense. They
must be replaced with one of same part
number or with an eq uivalent part if
replacement becomes necessary. Do not use
a replacement part of lesser quality or
substitute design. Torque values must be
used as specified during reassembly to
assure proper retention of all parts. There is
to be no welding as it may result in extensive
damage and weakening of the metal.

Electrical Circuit Inspection ProcedureS7RS0B0006001
While there are various electrical circuit inspection
methods, described here is a general method to check
its open and short circuit by using an ohmmeter and a
voltmeter.
Open Circuit Check
Possible causes for the open circuit are as follows. As
the cause is in the connector or terminal in many cases,
they need to be checked particularly carefully.
• Loose connection of connector
• Poor contact of terminal (due to dirt, corrosion or rust
on it, poor contact tension, entry of foreign object etc.)
• Wire harness being open
When checking system circuits including an electronic
control unit such as ECM, TCM, ABS control module,
etc., it is important to perfor m careful check, starting with
items which are easier to check.
1) Disconnect negative (–) cable from battery
2) Check each connector at both ends of the circuit being checked for loose connection. Also check lock
condition of connector if equipped with connector
lock. 3) Using a test male terminal
, check both terminals of
the circuit being checked for contact tension of its
female terminal. Check each terminal visually for
poor contact (possibly caused by dirt, corrosion, rust
entry of foreign object, etc.). At the same time, check
to make sure that each te rminal is locked in the
connector fully.
1. Check contact tension by inserting and removing just for once.

Perform sensor calibration according to “Sensor Calibration”.
Precautions in Speedometer Test or Other TestsS7RS0B4600005
When performing speedometer or other tests using speedometer tester or chassis dynamometer, ESP® function must
be deactivated by ESP ® OFF switch or using SUZUKI scan to ol to complete the tests correctly.
When using 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.
General Description
Electronic Stability Program DescriptionS7RS0B4601006
Electronic Stability Program (ESP ®) is an auxiliary function to enable the vehicle to av oid a danger safely while the
vehicle is running, stopping or turning.
Electronic Stability Program (ESP ®) consists of following functions.
ESP ® is a registered trademark of Daimler Chrysler AG.
Antilock Brake System (ABS)
This system prevents tire locking which may occur when br ake is applied suddenly or on slippery roads. With this
function, as the vehicle body is kept in the stable state an d tires unlocked, the driver can avoid any obstacle by turning
the steering wheel.
Electronic Brake force Distribution (EBD)
This function distributes braking force of front and rear wheels properly according to the vehicle load condition.
With this function, the braking force of the front and rear wheels is controlled for the optimum effect to secure the
maximum braking force regardless of the loadage.
Traction Control System (TCS)
This system controls the engine and brake to prevent the dr iving wheels from spinning at the time of starting and
accelerating. Particularly, this fu nction is helpful for safe driving on muddy or icy roads. When ESP ® control module
detects wheel spinning using information from the yaw rate sensor and wheel speed sensor, it lower the engine torque
by closing the electronic controlled thro ttle and controlling ignition. At the same time, brake is applied to the spinning
tire.
Stability Control
This function controls the vehicle body in the stable state by controlling the engine and braking so as to prevent the
vehicle from over-steering or under-steering while turning.
When under-steering occurs, this function lowers the engine torque and applies brake to the inner rear wheel in the
vehicle forward direction so as to pr event the vehicle from moving outward.
When over-steering occurs, this function applies brake to the outer front wheel in the vehicle forward direction so as to
prevent the vehicle from moving inward. Sensor Procedures required calibration
Steering angle sensor • Power is not su pplied to steering angle sensor. (battery, fuse and/or connector 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® hydraulic unit / control module assembly is replaced.
