Repair Instructions

Hydraulic Unit Operation Check

S5JB0B4606025

Refer to “Hydraulic Unit Operation Check in Section 4E”.

Sensor Calibration

S5JB0B4606087

CAUTION

!

 

If any DTC(s) other than C1075, C1076, C1077 
or C1078 are detected. 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

CAN communication circuit check
1) Disconnect connectors of all control modules 

communicating by means of CAN.

Is each CAN communication circuit between disconnected 
control modules (other than ESP

®

 control module and BCM) 

opened, shorted or high resistance?

Repair or replace the 
CAN communication 
line.

Go to Step 7.

DTC check for ESP

®

1) Connect connectors of disconnected control modules 

communicating by means of CAN.

2) Disconnect each connector and check DTC for ESP

® in 

turn.
• ECM
• BCM
• 4WD control module
• Immobilizer control module (ICM) (if equipped)
• Combination meter
• Steering angle sensor

Is DTC U1139 detected?

Check ESP

® control 

module power and 
ground circuit. If circuits 
are OK, substitute a 
known-good ESP

® 

hydraulic unit / control 
module assembly and 
recheck.

Check applicable 
control module power 
and ground circuit. If 
circuit is OK, substitute 
a known-good 
applicable control 
module and recheck.

3) Turn ignition switch to ON position and confirm that 

only any of DTC(s) C1075, C1076, C1077 and/or 
C1078 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 stepping on the brake.

CAUTION

!

 

Hold the above condition in Step 4) to 
calibrate sensor correctly until sensor 
calibration 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 calibration, turn ignition switch 

to OFF position and disconnect SUZUKI scan tool 
from DLC.

Steering Angle Sensor Calibration (Not Using 
SUZUKI Scan Tool)

CAUTION

!

 

When power is not supplied to the steering 
angle sensor by removing battery or fuse, 
steering angle sensor should be calibrated.

 

1) Set steering wheel in straight-ahead position.
2) Connect battery terminals and/or fuse and start 

engine.

CAUTION

!

 

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.
