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.

Warning Lamp, Indicator Lamp DescriptionS7RS0B4601003
There are five types of warning lamp and indicator lamp 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.
The followings are the condition and operation of warning lamps and indicator lamps.
CAN Communication System DescriptionS7RS0B4601004
Refer to “CAN Communication System Description in Section 1A” for CAN communication system description. ESP ®
control module communicates control data with each control module as follows.

Warning lamp / Indicator lamp Condition and operation
ABS warning lamp If ABS has abnor mality, the lamp turns “ON”.
EBD warning lamp (brake warning
lamp) • If EBD system has abnormality, the lamp turns “ON”.
• If bake fluid level in reservoir is lower
than minimum level, the lamp turns “ON”.
• Parking brake switch is ON, the lamp turns “ON”.
ESP ® warning lamp If ESP ® systems has abnormality, the lamp turns “ON”.
SLIP indicator lamp • If stability cont rol system and traction control system is active, the lamp blinks
at 5 Hz.
• If Steering angle sensor calibration is incompleted, the lamp blinks at 1 Hz.
ESP ® OFF lamp • If ESP ® OFF switch is turned “ON”, the ESP ® OFF lamp light up. When it is
“ON”, TCS and stability control system functions are controlled not to work.
• ESP® OFF lamp light up to indicate th at brake control of traction control
function is controlled not to act if brake pad temperature is over 320 °C (608 °F)
and any of wheel is in wheel spin condition.
