Longitudinal G Inspection
1)Park vehicle on level surface with parking brake applied and fix wheels with chocks.
2)Connect SUZUKI scan tool to DLC (1) with ignition “OFF”.
3)Calibrate yaw rate / G sensor. 
4)Set ignition “ON” and select “DATA LIST” of SUZUKI scan tool. Refer to Operator’s Manual of SUZUKI scan tool for further details.
5)Check “G Sensor” under “DATA LIST” of SUZUKI scan tool in the following vehicle conditions.
•Level condition
•Front-up condition
•Rear-up condition
Replace ESP® hydraulic unit / control module if check result is not as specified.•Front-up condition
•Rear-up condition
