Sensor Calibration of ESP®

NOTE:

If any DTC other than C1074, C1075 are detected, sensor calibration can not be completed. Repair trouble cause of DTC first.

ESP® hydraulic unit/control module assembly stores reference point of master cylinder pressure sensor and yaw rate/G sensor. Also steering angle sensor stores its own reference point.

Traction control or stability control is performed according to amount of variation from these reference points. If a reference point is lost or shifted due to following maintenance, calibration is needed.

ESP SENSOR CALIBRATION CHART

Sensor	Maintenance
Yaw rate/G sensor	Replace ESP® hydraulic unit/control module assembly (C1074)
Steering angle sensor	Replace ESP® hydraulic unit/control module assembly Replace steering angle sensor (C1075)
Master cylinder pressure sensor	Replace ESP® hydraulic unit/control module assembly Disconnect ESP® hydraulic unit/control module assembly

All sensors are calibrated at once when calibration is performed.

Set steering wheel in straight state.
Connect SUZUKI scan tool to DLC (1) with ignition mode of keyless push start system in "OFF".

Push engine switch to change ignition mode of keyless push start system to "ON" and confirm that no DTC is detected except C1074, C1075. If any DTC is detected, repair or replace trouble area.
Park vehicle on level surface, apply parking brake, stop engine with ignition mode of keyless push start system to "ON", set steering wheel in straight-ahead position and release brake pedal.
NOTE: Keep the above condition in Step 4) to calibrate sensor correctly until sensor calibration is completed.
Select menu "Sensor Calibration" under "Utility" mode of SUZUKI scan tool and calibrate sensor with ignition mode of keyless push start system in "ON". Refer to scan tool operator's manual for further details.
After completing the calibration, check DTC(s) is not stored in ESP® hydraulic unit/control module assembly.
Confirm that ignition mode of keyless push start system is in "OFF" and disconnect SUZUKI scan tool from DLC.
