Precautions in Sensor Calibration
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.
Sensor
Steering angle sensor
Master cylinder pressure sensor • ESP® hydraulic unit / control module assembly is removed or replaced.
Yaw rate / G sensor assembly
Perform sensor calibration according to "Sensor Calibration: ".
Precautions in Speedometer Test or Other Tests
When performing speedometer or other tests using speedometer tester or chassis dynamometer, ESP® function must
be deactivated by using SUZUKI scan tool (not by ESP® OFF switch) to complete the tests correctly. ESP® OFF
switch turns ESP® function off temporarily and ESP® function recovers and activates at 30 km/h (18.5 mph) or more.
Refer to SUZUKI scan tool operator's manual for further details.
Electronic Stability Program Description
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® is a registered trademark of Daimler Chrysler AG.
Procedures required calibration
• 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.
• Yaw rate / G sensor assembly is removed or replaced.
• ESP® hydraulic unit / control module assembly is replaced.

Electronic Stability Program:
ESP® Hydraulic Unit / Control Module
Assembly Description
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.
