4F-50 Electronic Stability Program: 

Yaw Rate / G Sensor Assembly Removal and 
Installation

S5JB0E4606018

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 in related manual”.

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.

2) Install yaw rate / G sensor assembly (1) to floor 

panel.

Tightening torque
Yaw rate / G sensor assembly bolt (a):  8 N·m (
0.8 kgf-m, 6.0 lb-ft)

3) Install console rear panel referring to “Console Box 

Components in Section 9H in related manual”.

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

S5JB0E4606019

• 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

S5JB0E4606020

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.

Steering angle Specification

Steering Angle Sensor Removal and Installation

S5JB0E4606021

Refer to “Steering Angle Sensor Removal and 
Installation in Section 6B”.

Steering Angle Sensor Inspection

S5JB0E4606022

• 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 steering angle sensor (1).

ESP

® OFF Switch Removal and Installation

S5JB0E4606023

Removal

1) Disconnect negative (–) cable at battery.
2) Remove center garnish with audio unit (if equipped) 

and HVAC control module referring to “Audio Unit 
Removal and Installation in Section 9C in related 
manual”.

3) Remove HVAC control module from center garnish, 

referring to “HVAC Control Module Removal and 
Installation in Section 7A in related manual”.

4) Remove ESP

® OFF Switch (1) from center garnish 

(2).
