Step 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

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.

Sensor Calibration
S7RS0B4606015
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.
