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.
