4F-46 Electronic Stability Program: 

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.
