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.

ABS Warning Lamp Does Not Come ON at Ignition Switch ONS7RS0B4604048
Wiring Diagram4
Check ESP ® control module power supply circuit
1) Turn ignition switch to OFF position.
2) Check for proper connection to ESP ® control module
connector at terminals “E85-1” and “E85-32”.
3) If OK, then turn ignition switch to ON position and measure voltage between each terminal of “E85-1”,
“E85-32” and vehicle body ground.
Are they 10 – 14 V? Go to Step 5. “WHT/BLU” and/or
“WHT/RED” circuit
open.
5 Check ESP ® control module ground circuit
1) Turn ignition switch to OFF and measure resistance between each terminal of “E85-16”, “E85-47” and vehicle
body ground.
Is resistance less than 2
Ω? Go to Step 6.
Ground circuit for ESP®
control module open or
high resistance.
6 CAN communication circuit check
1) Check CAN communication circuit between combination
meter and ESP ® control module referring to “DTC
U1073: Control Module Communication Bus Off”.
Is CAN communication circuit in good condition? Substitute a known-
good combination meter
and recheck. If warning
lamp remains ON,
substitute a known-
good ESP
® hydraulic
unit / control module
assembly and recheck. Repair or replace.

Repair Instructions
ESP® Hydraulic Unit Operation CheckS7RS0B4606025
1) Check that basic brake system other than ESP ® is
in good condition.
2) Check that battery voltage is 11 V or higher.
3) Lift up vehicle.
4) Set transmission to neutral and release parking brake.
5) Turn each wheel gradually by hand to check if braked ragging occurs. If it does, correct.
6) Connect SUZUKI scan tool to data link connector (DLC) (1) with ignition switch OFF.
Special tool
(A): SUZUKI scan tool
7) Turn ignition switch to ON position and select menu press / depress in “HYDRAULIC CONTROL TEST”
under “miscellaneous test” (“MISC. TEST”) mode of
SUZUKI scan tool.
Refer to SUZUKI scan tool operator’s manual for
further details.
8) Perform the following checks with help of another person.
• Depressurization checkStep on brake pedal (1) and then select testing
wheel by SUZUKI scan tool and the wheel (2)
should be turned by another person’s hand. At this
time, check whether the wheel rotates freely due
to brake depressurization. • Pressurization check
Step off brake pedal (1) and then select testing
wheel by SUZUKI scan tool and the wheel (2)
should be turned by another person’s hand. At this
time, check whether the wheel locks due to brake
pressurization.
NOTE
Pressurization / Depressurization by SUZUKI
scan tool is available for 0.5 second.

9) Check for all 4-wheels condition respectively. If a faulty condition is found, replace hydraulic unit /
control module assembly.
10) After completing the check, turn ignition switch to OFF position and disconnect SUZUKI scan tool from
DLC.
Sensor CalibrationS7RS0B4606015
CAUTION!
If any DTC(s) other than C1075, C1076 or
C1078 are detected, sensor calibration can
not be completed. Repair the detected DTC
first.

NOTE
Steering angle sensor calibration is needed
when battery, “DOME” fuse or the steering
angle sensor is removed.
This sensor calibration can be done with/
without SUZUKI Scan Tool.
When ESP ® control module and/or yaw rate /
G sensor assembly is removed, sensor
calibration is needed with SUZUKI Scan Tool.

Sensor Calibration (Using SUZUKI Scan Tool)1) Set steering wheel in straight-ahead position.
2) Connect SUZUKI scan tool to data link connector (DLC) (1) with ignition switch OFF.
Special tool
(A): SUZUKI scan tool
3) Turn ignition switch to ON position and confirm that
only any of DTC(s) C1075, C1076 and/or C1077 is
detected. If any other DTC are detected, repair the
detected DTC.
4) Park and level the vehicle with parking brake, stop engine with ignition switch ON, set steering in
straight and without step ping on the brake pedal.
NOTE
Hold the above condition in Step 4) to
calibrate sensor correctly until sensor
calibration is completed.

5) Select menu “SENSOR CALIBRATION” under
“MISC. TEST” mode of SUZUKI scan tool and
calibrate sensor. Refer to scan tool operator's
manual for further derails.
6) After completing the calibra tion, turn ignition switch
to OFF position and disconnect SUZUKI scan tool
from DLC. Steering Angle Sensor Calibration (Not Using
SUZUKI Scan Tool)
1) Set steering wheel in straight-ahead position.
2) Connect battery terminals and/or fuse and start engine.
NOTE
When power is not supplied to the steering
angle sensor by removing battery or fuse,
DTC C1075 is detected and SLIP indicator
lamp (1) flashes.
If DTC other than C1075 is detected, SLIP
indicator lamp flushes and other indicator
illuminate. In that case, repair the detected
DTC first.

3) Drive vehicle straight on level ground at 15 km/h (9.5 mph) or above for few seconds without spinning
wheels. And confirm that SLIP indicator lamp is OFF.
