Electronic Stability Program (Esp)

If the vehicle is equipped with ESP, once the battery is reconnected, the Steering Angle Sensor (SAS) within the Antilock Brake Module (ABM) needs to be calibrated. The SAS requires calibration (initialization) using the scan tool anytime the battery or an ABS (ESP) component has been disconnected for any length of time. If the SAS is not calibrated following battery reconnection, the ESP/BAS indicator lamp will flash continuously with no DTCs. 

To calibrate (initialize), perform the following:

1. Position the front wheels straight ahead and center the steering wheel.
2. Connect the scan tool to the vehicle.
3. Follow the directions on the scan tool.
