km/h (6.2 mph).

• Minimum turning radius is 5.3 m (17.4 ft).

 

Yaw Rate / G Sensor Assembly Removal and 
Installation

S6JB0B4606018

CAUTION

!

 

• When yaw rate / G sensor assembly is 

replaced, ESP

® control module needs zero 

calibration. Perform zero calibration by 
SUZUKI scan tool referring to “Sensor 
Calibration”.

• Regarding yaw rate / G sensor assembly 

removal/installation, confirm specified 
torque and never use impact wrench to 
avoid damage.

• When handling the yaw rate / G sensor 

assembly, be careful not to drop it or apply 
an impact to it.
If an excessive impact was applied, never 
attempt disassembly or repair but replace 
it with a new one.

 

Removal

1) Disconnect negative (–) cable at battery.
2) Remove console rear panel referring to “Console 

Box Components in Section 9H”.

3) Remove yaw rate / G sensor assembly from floor 

panel.

Installation

1) Before installing yaw rate / G sensor assembly (1), 

check installing condition as follows.
• Deformations around sensor installation area (2) 

(in floor panel).

• Foreign matters on mating surface between 

sensor and floor panel.

3) Install console rear panel referring to “Console Box 

Components in Section 9H”.

4) Connect negative (–) cable to battery.
5) After completing installation, calibrate yaw rate / G 

sensor assembly referring to “Sensor Calibration”.

Yaw Rate / G Sensor Inspection

S6JB0B4606019

• Check sensor for dents, cracks or deformation.
• Check sensor connector (sensor side and harness 

side) and sensor connector lock mechanism for 
damage or crack.

• Check connector terminals for bend, corrosion or rust.
If it is found faulty, replace yaw rate / G sensor assembly.

Steering Angle Sensor On-Vehicle Inspection

S6JB0B4606020

CAUTION

!

 

Before each inspection, confirm steering 
angle sensor calibration is completed.
If calibration is incompleted, calibrate sensor 
referring to “Sensor Calibration”.

 

1) Connect SUZUKI scan tool to data link connector 

(DLC) (1) with ignition switch OFF.

Special tool
(A):  SUZUKI scan tool 

2) Turn ignition switch to ON position and select menu 

“DATA LIST” mode of SUZUKI scan tool.
Refer to scan tool operator's manual for further 
derails.

3) Check “Steering angle Sen” under “DATA LIST” of 

SUZUKI scan tool in the following steering wheel 
conditions.
• Front wheels in straight-ahead position
• Rotate steering wheel a round in clockwise 

(counter clockwise) from straight-ahead position

If steering angle condition is out of specification, 
replace steering angle sensor.
