Suzuki Grand Vitara JB416 / JB420 (ESP model). Manual — part 73

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.
