24. For Vehicles equipped with the "Auto-Up" front window feature, calibrate the door module using the following procedure:

a. Turn the ignition to the "Run" position.

b. Regardless of current window position, move the driver side front window upward until the window stalls in the full up position. Allow the window motor to stall for at least 2 seconds before releasing the window switch.

c. Move the driver side front window downward until the window stalls in the full down position. Allow the window motor to stall for at least 2 seconds before releasing the window switch.

d. Move the driver side front window upward until the window stalls in the full up position. Allow the window motor to stall for at least 2 second before releasing the window switch.

e. Repeat steps 24a. through 24d. to calibrate the module for the passenger side front window.

f. Verify the windows are properly calibrated by operating the "Auto-Up" feature on the windows. Repeat this procedure if the calibration failed.

25. For Vehicles equipped with Electronic Stability Program (ESP), calibrate the Steering Angle Sensor (SAS) using the following procedure:

CAUTION:
If the vehicle is equipped with Electronic Stability Program (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 wiTECH scan tool. If the SAS is not calibrated following battery reconnection, the ESP/BAS indicator lamp will flash continuously with no Diagnostic Trouble Codes (DTC's).

a. Position the front wheels straight ahead and center the steering wheel.

b. Connect the wiTECH pod to the vehicle data link connector.
