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.
