Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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:
- Position the front wheels straight ahead and center the steering wheel.
- Connect the scan tool to the vehicle.
- Follow the directions on the scan tool.
