Step Action YesNo
1 Was “Electronic Stability Pr ogram Check” performed? Go to Step 2.Go to “Electronic
Stability Program
System Check”.
2 Check power supply circuit from battery
1) Disconnect ESP ® hydraulic unit / control module

2) Check for proper connection to ESP ® control module
connector at terminals “E83-1”, “E85-16” and “E85-47”.
3) If OK, then turn ignition switch to ON position and measure voltage between terminals “E85-1” and “E85-
16”, “E85-47”.
Are voltage 9.7
± 0.3 V or more? Go to Step 5. Go to Step 3.
3 Check ESP ® control module ground circuit
1) Measure resistance between each terminal of “E85-16”, “E85-47” and vehicle body ground.
Is resistance less than 2
Ω? Go to Step 4. “BLK” wire circuit in
open or high resistance.
4 Check power supply circuit from battery
1) Measure voltage between positive battery terminal and
vehicle body ground with engine running.

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
3) Turn ignition switch to ON position and confirm that
only any of DTC(s) C1075, C1076 and/or C1077 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 step ping on the brake pedal.
NOTE
Hold the above condition in Step 4) to
calibrate sensor correctly until sensor
calibration is 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 calibra tion, turn ignition switch
to OFF position and disconnect SUZUKI scan tool
from DLC. Steering Angle Sensor Calibration (Not Using
SUZUKI Scan Tool)
1) Set steering wheel in straight-ahead position.
2) Connect battery terminals and/or fuse and start engine.
NOTE
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.
