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

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

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.

Electronic Stability Program ConstructionS7RS0B4601007
ESP® control module/ hydraulic unit
The control module receives signals from each wheel speed sensor, ESP O FF switch, brake master cylinder pressure
sensor, steering angle sensor and yaw rate / G sensor. Ba sed on these signals as information, the control module
judges the vehicle conditions and controls the brake hydraulic pressure by combining the ON/OFF operation of the
solenoid in the hydraulic unit and the pump motor operation.
The hydraulic unit contains an inlet so lenoid valve and an outlet solenoid valve for each wheel as well as a cut
solenoid valve and a low pressure solenoid valve for each hydraulic unit system. Also, a master cylinder pressure
sensor, pump motor, etc. are included. The hydraulic pre ssure control is done in 3 modes of pressure increase,
pressure keeping and pressure reduction.

Downloaded from www.Manualslib.com manuals search engine 4F-4 Electronic Stability Program:
• Pump motor:The pump motor turns on and applies pressure to each brake when braking is activated in the TCS and stability
control state. When in the pressure reduction mode, it causes the brake fluid in the reservoir to return to the master
cylinder.
• Brake master cylinder pressure sensor: This sensor detects the brake hydraulic pressure in th e primary piping when brake is applied in the normal
condition. Also, it detects the pump motor driving state wh en brake is applied in the TCS and Stability Control state.
• Inlet solenoid valve: In the ABS, TCS and Stability Control stat e, this valve is activated in the pressure keeping and pressure reduction
modes to open the fluid passage, thereby restricting increase of the hydraulic pressure applied to the brake caliper.
• Outlet solenoid valve: In the ABS, TCS and Stability Control state, this valve is activated in the pressure reduction mode to open the fluid
passage, thereby lowering the hydraulic pressure kept in the brake caliper.
• Cut solenoid valve: When brake is applied in the TCS and Stability Control state, this valve is activated to close the fluid passage,
thereby causing the hydraulic pressure generated by the pump motor to apply to the brake caliper.
• Low pressure solenoid valve: When brake is applied in the TCS and Stab ility Control state, this valve is activated to open the fluid passage from
the master cylinder to the pump motor.
Steering angle sensor
The steering angle sensor is assembled with the contact co il as a unit and mounted to the steering column. Detecting
the angle as the steering wheel is turned, it sends that information to the ESP ® control module.
